Camera tracking integration =========================== - Initial implementaiton of new ID named MovieClip. Currently it has plactically the same functionality as images, but this functionality would be widen in nearest future. - Initial implementation of SpaceClip. This space is supposed to be used for acting with MovieClips (opening, playbacking, math-moving interaction and so on). Currently you could open image sequence/movie file here, pan/zoom, use a playback here. I've added cache visualizer to this space, but it's currently more a developer's feature to see how cache system works, but it could be adopted for further artists' usage (something like cache visuzlizer for simulations). - Added new theme area for Space Clip. No special colors were defined here yet. - Implementation of basic cache system for movies. This cache system is very familiar with sequence cache system, but it supposed to be more portable: at least cache keys aren't limited with sequence-based data and current seqcache could became an interface between sequencer and moviecache without much logic (only logic related on keys handling would be necessary here). Implemented basic limitors (ab\mount of cached imbuf's), so it'll be a bit more difficult to go out of memory when playing long animations in Image Editor (this cache system could be used for images too, in the future). - Very basic tools implementation -- only sceletion added, no real tool implemented (only camera focal length added to the UI which hasn't got real affect on anything). Assorted notes: - Not sure about best behaviour for Unlink clip button: should it be imageeditor-like (with de-referencing only) or text-editor like (with removing datablock from file). - Also not sure if tools/properties should be splitted into different areas or it'll be better to have tools and settings for this tool/item/etc in the same area (tools at the top, properties are under them). Code for properties area is '#if 0'-ed. - Sound isn't supported during playback in movie clip.

Camera tracking integraiton =========================== - Corrected copyrights in my new files header. - Added debug option to dump as PNG image content of search areas tracking between which was failed. - Removed internal tracking settings like pyramid level and tolerance. Weren't useful neither for me nor for artists. - Fixed bug in BKE_tracking_get_marker which could lead to failure of getting marker for current frame when there's marker for requested frame. - Fixed bug with disappearing markers after tracking for cases when marker was added at frame different from tracking start frame and tracking start frame is equal to tracking end frame. - Stop tracking when no markers could be tracked. - Changed marker selection rules: * If marker isn't selected, all it's areas are getting selected with mouse. * If marker is selected and selection type doesn't have "extend" mode (SHIFT isn't holded down) the nearest to mouse cursor area would be selected. All the reast areas would loose selection. - Limit number of frames which would be used in "Track Markers" operator. So now you could easily track along 10/20/etc frames. - Change scene current frame after "Track Markers" operator. - Implemented speed limitors. Now tracking could happen: * As fast as possible * With reatime speed (scene FPS) * With half of realtime speed * With quarter of realtime speed. - Got rid of orig_user in MovieTrackingContext and user in TrackMarkersJob. This prevents crashes when user joins some space to SpaceClip from which tracking was started. - Made keyframes on path bigger and do not draw keyframes for non-selected markers. TODO: need to get rid of storing main, scene and screen in TrackMarkersJob. This is needed to set scene's current frame after tracking (such behavior is comfortable for artists) but this could lead to crash if scene is getting removed when tracking job is running. Render animation operator also stores scene and main, so such solution could be fine for first time before we've got something smarter.

Camera tracking integration =========================== Implemented basic structures and operators for markers manipulaiton. Markers contains: - Position of marker at frame in unified 0..1 coordinates - Relative positions of left-bottom and right-top corners of pattern area - Relative positions of left-bottom and right-top corners of search area - Selection flags New operators: - Create new maerker. It's a modal operator which creates markers at mouse position when LMB is clicking. - Delete selected markers. - Select marker using RMB. Some parts of marker (point, patter, search) could be deselected. - Select markers using rectangular selection. - Select markers using circle selection. - Marker translation (G-key). - Marker scaling (S-key). UI changes: - Added mode to space clip. Currently supported modes are: * View mode * Tracking mode This was intended to separate different categories of tools, so interface shouldn't be overheaded with plenty of tools which aren't actually using in the same time. - Created new panel when actiev tool is 'MARKER' and there's active marker where positions could be adjusted in pixel space. Internal changes: - Splitted DNA/RNA movieclip files to make separation of tracking data and movie data more clear. This could be useful in the future when we'll want to support multiplie moies for single camera tracking (to make tracking more accurate). - Added new file in blenkernel, where all tracking-related function would be stored. Not very much function here at this moment, but in the future all stuff related on converting DNA to external tracking data would be stored here.

Camera tracking integration =========================== - itasc adopted for Eigen3 library. It compiles well, but need deeper testing for regressions. - Removed Eigen2 library. - Added settings to tracker which could be changed from UI. - Pattern area is now affects on tracker. Currently libmv supports square patterns which are centered to marker's position. Maximal pattern dimensions is sending to libmv as pattern size. Would be changed when libmv would support non-centered and non-square patterns. - Fixed bug with syncing pattern's flags when tracking. - Current frame in cache line became a bit more visible. It's useful for me to when debugging. - Changed behaviour of "Add Marekr" operator: not it's non-modal and places marker on mouse position at click. - Added macro "Add Marekr and Move" which is used to place markers from toolbar button. - Added some utility functions to get image buffer under search and pattern area which also returns relative position of marker center for this images. Generated images are more "correct" from coords rounding POV, but re-calculation of marker position back to frame coords is more complicated and not implemented yet, so old not very accurate logic is still used. - Added preview widget with content of pattern area. NOTE: files saved in previous versions of this branch could easily crash on tracking. Use "Reset To Settings" button from Tracking Settings before tracking selected markers for such files. TODO: - Implement adjusting marker position from marker's preview widget. - We've got an idea of sliding marker after click before releasing mouse button.

struct ImBuf;
Camera tracking integration =========================== - Disallow moving pattern/search area in way when marker position is outside of pattern area. - MoiveClip could be set as background for 3D view. Added background source property to BGPic to switch between image and movie. Movie is a bit more complicaated entity than clip (due to displaying bundles, test objects and so) that's why i've sliptted background into two sources. - Added Layout.template_movieclip to display general clip settings. Used in Footage panel of SpaceClip and background image properties in 3d view. - Display bundles in 3D view as spheres. Selection is synchronized to markers associated with this bundle. Bundle can't be selected in 3D view. - Recoded internal DNA structures, RNA and operators to match libmv entities. Tracking data now consists of Tracks, each tracks consists of markers which are associated with frame number. Markers holds position only, pattern and search areas settings are stored in track. Such settings should be unified for all markers in track and marker should hold position and frame number only.

struct MovieTracking;
Camera tracking integration =========================== - Added missed stub for blenderplayer, so it should compile again fine. - libmv is added to extern/. Script for bundling needed subset of sourcses from libmv repo is included there. - Eigen3 is also added to extern/. libmv depends on Eigen3 (which isnt't compatible with Eigen2 from API point of view). So both of versions are going to be in worktree for time (until code which used Eigen2 would be ported to Eigen3). - Added some functions to libmv-capi, so some things from this library could already be used. - Added the very basic implementation of 2D tracking. It should be treated as draft for tracking architecture which probably would be cleaned up, changed or whatever else. Current implementation was supposed to demonstrate that our structures and understading is correct to interact with libmv easily.

void BKE_tracking_track_flag(struct MovieTrackingTrack *track, int area, int flag, int clear);
void BKE_tracking_insert_marker(struct MovieTrackingTrack *track, struct MovieTrackingMarker *marker);
Camera tracking integration =========================== - Internal changes: * Fixed bundle.sh script to bundle libmv: it was generating incorrect CMakeLists header. * Rename CLIP_OP_delete to CLIP_OT_delete_track. * Fixed crash when BKE_movieclip_acquire_ibuf is called with NULL user. * Made MovieTrackingMarker structure 8-bytes aligned * Use writestruct rather than writedata for track markers. This allows to change MovieTrackingMarker safely. - Added "Delete Marker" operator which deletes marker for current frame only. Hotkey is Shift-Del. - Added MovieClip.size and MovieClip.resolution RNA properties. Use last accessed frame number to get ImBuf from sequence. - Added different actions for "Clear Path" operator: * Clear path up to current frame. * Clear the whole path. * Cleat remained part of path (for frames after current). - Changed buttons order and icons for tracking. New order is: * Track frame backwards. * Track sequence backwards. * Track sequence forwards. * Track frame forwards. NOTE: this breaks compatibility with existing .blend files again, but it should be much easier to change data structures without breackaged in the future.

struct MovieTrackingMarker *BKE_tracking_get_marker(struct MovieTrackingTrack *track, int framenr);
Camera tracking integration =========================== - Fixed "sliding" when panning footage in high zoom. This was most noticeable near right top corner of footage. - Fixed 1px flickering of marker during playback with "Lock to Selection" toggled on. This was caused by precision errors. Used UI_view2d_to_region_no_clip-like offsets calculations, but in float values. Maybe there could be something smarter.. - Implemented tarcking along single frame. Hotkey is ALT+left/right array. Also changed a bit tracking tools buttons in Tools panel. - Fixed "Lock to Selection" during tracking -- tracks synchronization should happen before centering view. - Approximate marker's position for frames, which haven't got marker for them. Use the nearest marker from left side for approximation. For frames above first marker's framenr sue first marker position. - Markers now could be disabled. Added checkbox to "Active Marker" panel. - Changes in cache line: * Bright line means active track has marker for frame. * Dark line means marker's position is approximated. * Yellow-less line means marker is disabled for that frames. NOTE: .blend files which are saved with previous tomato version would fail to work properly. I don't want to spend time on making that files work properly atm, so don't blame on this.

It should be treated as draft for tracking architecture which probably would be cleaned up, changed or whatever else. Current implementation was supposed to demonstrate that our structures and understading is correct to interact with libmv easily.

struct MovieTrackingTrack *BKE_tracking_copy_track(struct MovieTrackingTrack *track);
Camera tracking integration =========================== - Internal changes: * Fixed bundle.sh script to bundle libmv: it was generating incorrect CMakeLists header. * Rename CLIP_OP_delete to CLIP_OT_delete_track. * Fixed crash when BKE_movieclip_acquire_ibuf is called with NULL user. * Made MovieTrackingMarker structure 8-bytes aligned * Use writestruct rather than writedata for track markers. This allows to change MovieTrackingMarker safely. - Added "Delete Marker" operator which deletes marker for current frame only. Hotkey is Shift-Del. - Added MovieClip.size and MovieClip.resolution RNA properties. Use last accessed frame number to get ImBuf from sequence. - Added different actions for "Clear Path" operator: * Clear path up to current frame. * Clear the whole path. * Cleat remained part of path (for frames after current). - Changed buttons order and icons for tracking. New order is: * Track frame backwards. * Track sequence backwards. * Track sequence forwards. * Track frame forwards. NOTE: this breaks compatibility with existing .blend files again, but it should be much easier to change data structures without breackaged in the future.

void BKE_tracking_clear_path(struct MovieTrackingTrack *track, int ref_frame, int action);
Camera tracking integration =========================== - Disallow moving pattern/search area in way when marker position is outside of pattern area. - MoiveClip could be set as background for 3D view. Added background source property to BGPic to switch between image and movie. Movie is a bit more complicaated entity than clip (due to displaying bundles, test objects and so) that's why i've sliptted background into two sources. - Added Layout.template_movieclip to display general clip settings. Used in Footage panel of SpaceClip and background image properties in 3d view. - Display bundles in 3D view as spheres. Selection is synchronized to markers associated with this bundle. Bundle can't be selected in 3D view. - Recoded internal DNA structures, RNA and operators to match libmv entities. Tracking data now consists of Tracks, each tracks consists of markers which are associated with frame number. Markers holds position only, pattern and search areas settings are stored in track. Such settings should be unified for all markers in track and marker should hold position and frame number only.

void BKE_tracking_free(struct MovieTracking *tracking);
Camera tracking integration =========================== - Initial implementaiton of new ID named MovieClip. Currently it has plactically the same functionality as images, but this functionality would be widen in nearest future. - Initial implementation of SpaceClip. This space is supposed to be used for acting with MovieClips (opening, playbacking, math-moving interaction and so on). Currently you could open image sequence/movie file here, pan/zoom, use a playback here. I've added cache visualizer to this space, but it's currently more a developer's feature to see how cache system works, but it could be adopted for further artists' usage (something like cache visuzlizer for simulations). - Added new theme area for Space Clip. No special colors were defined here yet. - Implementation of basic cache system for movies. This cache system is very familiar with sequence cache system, but it supposed to be more portable: at least cache keys aren't limited with sequence-based data and current seqcache could became an interface between sequencer and moviecache without much logic (only logic related on keys handling would be necessary here). Implemented basic limitors (ab\mount of cached imbuf's), so it'll be a bit more difficult to go out of memory when playing long animations in Image Editor (this cache system could be used for images too, in the future). - Very basic tools implementation -- only sceletion added, no real tool implemented (only camera focal length added to the UI which hasn't got real affect on anything). Assorted notes: - Not sure about best behaviour for Unlink clip button: should it be imageeditor-like (with de-referencing only) or text-editor like (with removing datablock from file). - Also not sure if tools/properties should be splitted into different areas or it'll be better to have tools and settings for this tool/item/etc in the same area (tools at the top, properties are under them). Code for properties area is '#if 0'-ed. - Sound isn't supported during playback in movie clip.
2011-05-30 04:18:02 +00:00
Camera tracking integration =========================== - Fixed bug with swapped width/height used for per-pixel cycle when disabling color channel to be used for tracking. - Marker preview is now using sub-pixel precision. - Tracking stuff uses the same imbug generation function as preview area does. Sub-pixel precision should be ok now here too.

struct ImBuf *BKE_tracking_acquire_search_imbuf(struct ImBuf *ibuf, struct MovieTrackingTrack *track,
struct MovieTrackingMarker *marker, int margin, float pos[2], int origin[2]);
Camera tracking integration =========================== - itasc adopted for Eigen3 library. It compiles well, but need deeper testing for regressions. - Removed Eigen2 library. - Added settings to tracker which could be changed from UI. - Pattern area is now affects on tracker. Currently libmv supports square patterns which are centered to marker's position. Maximal pattern dimensions is sending to libmv as pattern size. Would be changed when libmv would support non-centered and non-square patterns. - Fixed bug with syncing pattern's flags when tracking. - Current frame in cache line became a bit more visible. It's useful for me to when debugging. - Changed behaviour of "Add Marekr" operator: not it's non-modal and places marker on mouse position at click. - Added macro "Add Marekr and Move" which is used to place markers from toolbar button. - Added some utility functions to get image buffer under search and pattern area which also returns relative position of marker center for this images. Generated images are more "correct" from coords rounding POV, but re-calculation of marker position back to frame coords is more complicated and not implemented yet, so old not very accurate logic is still used. - Added preview widget with content of pattern area. NOTE: files saved in previous versions of this branch could easily crash on tracking. Use "Reset To Settings" button from Tracking Settings before tracking selected markers for such files. TODO: - Implement adjusting marker position from marker's preview widget. - We've got an idea of sliding marker after click before releasing mouse button.
2011-06-14 16:22:06 +00:00
Camera tracking integration =========================== - libmv's sources would now be added to qtcreator project. - Fixed compilation with blenderplayer enabled and cmake. - Fixed bug when tracking was done from frame different from initial marker's frame number. - Implemented backwards tracking. - Added option to draw track's path. Would be enabled by default for new scenes. Could be enabled on "Display" panel for files saved in previous version. - Added operator to clean track path so it could be easily tracked form scratch. - Added hotkeys for tracking, backwards tracking and cleaning track path (Ctrl-T, Ctrl-Shift-T and Alt-T). - Fixed crash when setting clip as a footage. - Small optimization when trying to track without selected markers.

struct MovieTrackingContext *BKE_tracking_context_new(struct MovieClip *clip, struct MovieClipUser *user, int backwards);
Camera tracking integration =========================== - Added missed stub for blenderplayer, so it should compile again fine. - libmv is added to extern/. Script for bundling needed subset of sourcses from libmv repo is included there. - Eigen3 is also added to extern/. libmv depends on Eigen3 (which isnt't compatible with Eigen2 from API point of view). So both of versions are going to be in worktree for time (until code which used Eigen2 would be ported to Eigen3). - Added some functions to libmv-capi, so some things from this library could already be used. - Added the very basic implementation of 2D tracking.

void BKE_tracking_context_free(struct MovieTrackingContext *context);
void BKE_tracking_sync(struct MovieTrackingContext *context);
Camera tracking integraiton =========================== - Corrected copyrights in my new files header. - Added debug option to dump as PNG image content of search areas tracking between which was failed. - Removed internal tracking settings like pyramid level and tolerance. Weren't useful neither for me nor for artists. - Fixed bug in BKE_tracking_get_marker which could lead to failure of getting marker for current frame when there's marker for requested frame. - Fixed bug with disappearing markers after tracking for cases when marker was added at frame different from tracking start frame and tracking start frame is equal to tracking end frame. - Stop tracking when no markers could be tracked. - Changed marker selection rules: * If marker isn't selected, all it's areas are getting selected with mouse. * If marker is selected and selection type doesn't have "extend" mode (SHIFT isn't holded down) the nearest to mouse cursor area would be selected. All the reast areas would loose selection. - Limit number of frames which would be used in "Track Markers" operator. So now you could easily track along 10/20/etc frames. - Change scene current frame after "Track Markers" operator. - Implemented speed limitors. Now tracking could happen: * As fast as possible * With reatime speed (scene FPS) * With half of realtime speed * With quarter of realtime speed. - Got rid of orig_user in MovieTrackingContext and user in TrackMarkersJob. This prevents crashes when user joins some space to SpaceClip from which tracking was started. - Made keyframes on path bigger and do not draw keyframes for non-selected markers. TODO: need to get rid of storing main, scene and screen in TrackMarkersJob. This is needed to set scene's current frame after tracking (such behavior is comfortable for artists) but this could lead to crash if scene is getting removed when tracking job is running. Render animation operator also stores scene and main, so such solution could be fine for first time before we've got something smarter.

int BKE_tracking_next(struct MovieTrackingContext *context);
Camera tracking integration =========================== - Removed unneeded checking of marker==NULL - Tracks could be named now. - Implemented "Follow Track" constraint to "parent" objects to tracks from movie clip. - Added operator to create such constraint for active object using clip and track from current context.

Camera tracking integration =========================== Implemented basic structures and operators for markers manipulaiton. Markers contains: - Position of marker at frame in unified 0..1 coordinates - Relative positions of left-bottom and right-top corners of pattern area - Relative positions of left-bottom and right-top corners of search area - Selection flags New operators: - Create new maerker. It's a modal operator which creates markers at mouse position when LMB is clicking. - Delete selected markers. - Select marker using RMB. Some parts of marker (point, patter, search) could be deselected. - Select markers using rectangular selection. - Select markers using circle selection. - Marker translation (G-key). - Marker scaling (S-key). UI changes: - Added mode to space clip. Currently supported modes are: * View mode * Tracking mode This was intended to separate different categories of tools, so interface shouldn't be overheaded with plenty of tools which aren't actually using in the same time. - Created new panel when actiev tool is 'MARKER' and there's active marker where positions could be adjusted in pixel space. Internal changes: - Splitted DNA/RNA movieclip files to make separation of tracking data and movie data more clear. This could be useful in the future when we'll want to support multiplie moies for single camera tracking (to make tracking more accurate). - Added new file in blenkernel, where all tracking-related function would be stored. Not very much function here at this moment, but in the future all stuff related on converting DNA to external tracking data would be stored here.
