Added occlusion culling capability in the BGE.
More info: http://wiki.blender.org/index.php/Dev:Ref/Release_Notes/2.49/Game_Engine#BGE_Scenegraph_improvement
MSVC, scons, cmake, Makefile updated.
Other minor performance improvements:
- The rasterizer was computing the openGL model matrix of the objects too many times
- DBVT view frustrum culling was not properly culling behind the near plane:
Large objects behind the camera were sent to the GPU
- Remove all references to mesh split/join feature as it is not yet functional
* Copying objects with animation data now works correctly. Previously, actions were not getting copied correctly, leading to loss of data in some cases.
* Action and Graph editors now display the name of the Action concerned (for 'Action' folder channels), making it easier to tell which AnimData blocks are sharing the same actions
* Added some code to make relative KeyingSets (converted from absolute ones) work better.
* Invalid drivers are now tagged accordingly and are not evaluated until they are manually refreshed using the 'Update Dependencies' button
* Drivers with errors have a error warning shown in their UI
* Rearranged the UI buttons a bit for drivers, adding support for a 'remove' driver button.
- Most mesh particle effectors can now have their effection point taken per particle as the nearest point on the mesh surface.
- This is activated with the "surface" button in the effector field panel.
- Activating the option adds a "surface" entry to the modifier stack where the state of the mesh is read from.
For an example of usage see http://www.youtube.com/watch?v=3XkO1EAmJks.
* Fix to make python panels callbacks get the actual
blender Panel as an argument, instead of any instance.
* Fix for callback validation in python 2.5, worked OK
in python 3.0 but gave error in 2.5 because it's a
method instead of a function there.

This commit contains a number of performance improvements for the
BGE in the Scenegraph (parent relation between objects in the
scene) and view frustrum culling.
The scenegraph improvement consists in avoiding position update
if the object has not moved since last update and the removal
of redundant updates and synchronization with the physics engine.
The view frustrum culling improvement consists in using the DBVT
broadphase facility of Bullet to build a tree of graphical objects
in the scene. The elements of the tree are Aabb boxes (Aligned
Axis Bounding Boxes) enclosing the objects. This provides good
precision in closed and opened scenes. This new culling system
is enabled by default but just in case, it can be disabled with
a button in the World settings. There is no do_version in this
commit but it will be added before the 2.49 release. For now you
must manually enable the DBVT culling option in World settings
when you open an old file.
The above improvements speed up scenegraph and culling up to 5x.
However, this performance improvement is only visible when
you have hundreds or thousands of objects.
The main interest of the DBVT tree is to allow easy occlusion
culling and automatic LOD system. This will be the object of further
improvements.
- Explode didn't use the dmcache index for getting the particles emitter position.
- One "tri or quad"-comparison tested the wrong index. Leading to one quad converting into a tri.
If the density texture was taken into account with hair parent particles there were cases when there weren't any parents left to interpolate children from. Now a density texture is only taken into account for hair child particles.
-Virtual parents were not randomly selected due to optimization in child particle distribution code.
-Wave-kink had a wrong matrix multiplication.
-Amount of virtual parents wasn't scaled properly to the amount of children rendered.
-Calculating virtual parents is now thread safe.
- I key over a button inserts a keyframe.
- Alt+I removes a keyframe.
- With right mouse button a menu with these options pops up.
- Buttons are colored green if the property is animated, yellow
if it is on a keyframe. I followed the colors from the UI
mockups, but the flicker on keyframes seems too distracting in
practice?
- This only works for properties on the ID itself at the moment,
path callbacks need to be filled in for all structs but mesh
still.
- It doesn't work when you're over a related label, that needs to
be made to work.
- I made it insert keyframes outside of any keyingset. Not sure
how this is supposed to integrate?
- Register python panels
- Added a generic class checking function BPY_class_validate() for panels/operators.
- No button drawing yet
Brecht, Added RNA_enum_value_from_id() and RNA_enum_id_from_value() to rna_access.c to do lookups between identifiers and values of EnumPropertyItem's, Not sure if these should go here.
When inserting keyframes in the 3D-View (support will be extended to other editors in due course) using the IKEY hotkey, the menu which appears will now consist of 3 parts:
* 'Active Keying Set' - this option allows you to use the user-defined KeyingSet which is active for the current scene (i.e. the one seen in the TimeLine/Outliner headers)
* User defined Keying Sets - a list of all such available KeyingSets is included, and entries can be chosen from there
* Built-In Keying Sets - see later...
To achieve this, several changes needed to be made first:
* Added support for 'relative' in addition to 'absolute' Keying Sets. Relative Keying Sets are Keying Sets which operate on data from the current context (i.e. a 'location' KeyingSet will add location keyframes for selected objects/bones/nodes as opposed to location keyframes for some particular object). The is a tentative 'templates' requirement system here, which still needs to be fully fleshed out.
* Added support for builtin Keying Sets (i.e. 'Location', 'Rotation', 'Scaling', and 'LocRot' as a few initial demonstrations), which replaces the temporary Insert Keyframe operator for the 3D-View (IKEY). These are effectively relative Keying Set definitions which are included in Blender by default and stored in a list separate from user-defined ones. Volunteer help in defining a few more of these for other editors will be welcome soon.
* Removed/replaced much of the crappy temporary Keyframing operator code, though a few tweaks could still be done.
ffmpeg format switched from RGBA32 to BGR32, it's no longer needed to swap color planes.
NOTE: this commit also attempts to fix the big endian case, but since I don't have a machine to test it, I'd appreciate if someone else would.
own fault, broke rev16702.
Curves created by fonts didnt have their radius set. Forgot do do this when making radius calculated with the curve (like tilt)
EditMesh *EM_GetEditMesh(Mesh *me);
void EM_EndEditMesh(Mesh *me, EditMesh *em);
as discussed on the mailling list, this is to facilitate migration to bmesh.
next step is to merge this this to the bmesh branch. this was done in the 2.5
branch to prevent too great a divergance.
also, made makesdna/makesrna work on cygwin/msvc2008/scons.
* Added a PanelType and HeaderType for registering panels
and headers in regions. When the region draws, it will
then automatically draw the ones that were registerd with
poll and draw callbacks.
Used for text header, properties and object buttons now.
this can be brought back as a new space if someone decides to
work on it.
This also fixes remaining issues with the outliner tree open
and close buttons not working sometimes.
This setting means that instead of blindly replacing the existing values, the generator modifier will instead apply its effects on top of any existing modifiers (and/or curve data).
Thus, it is now possible to apply effects such sin/cos-based oscillations on top of keyframed motion.
* Screen level regions created for menus are now a separate
CTX_wm_menu in the context, so they don't interfere with
existing regions.
* Fix context in popup menus to always come from the area
and region the popup was opened from.
* Removed some unused context stuff: tasks and reports.
The places that were using context reports were using it
wrong anyway.
* Fix F6 closing immediately after editing a button, by
making uiBlockSetFlag not clear existing flags anymore.
* Don't use ":" in boolean X/Y/Z buttons.
TEX and CMP to follow.
Also, renumbered the texture nodes because when I first wrote them I thought
they could share ID numbers with the SH and CMP nodes. D'oh!
* Envelope modifier now works correctly. Previously, the mapping was being done in the wrong order.
* Extra controls for modifiers now only draw when the F-Curve is the active one, so the view will be less cluttered in other cases.
Got the basic envelope modifier code working, including primitive drawing of relevant helper info in the graph view. It doesn't work in a very intuitive way yet, so I will recode it soon.
[18429] Typo in IPO Actuator
[18377] Crash fo yofankie (G.curscreen==NULL)
/* No screen, happens when saving a blendfile in background mode,
* then loading in the game engine
* just assume we need the mesh info */
* Made it based on string lookups rather than fixed enum, to make
it extensible by python scripts.
* Context callbacks now also have to specify RNA type when returning
pointers or collections. For non-RNA wrapped data, UnknownType can
be used.
* RNA wrapped context. The WM entries are fixed, for data context
only main and scene are defined properties. Other data entries have
to be dynamically looked up.
* I've added some special code in python for the dynamic context
lookups. Tried to hide it behind RNA but didn't find a clean way to
do it yet. Still unused/untested.
* Also minor fix for warning about propertional edit property in
transform code, and fix for usage of operator poll with checking if
it was NULL.
Notes:
* Sequence transform strip uses G.scene global, this is commented
out now, should be fixed.
* Etch-a-ton code was most difficult to merge. The files already in
2.5 got merged, but no new files were added. Calls to these files
are commented out with "XXX etch-a-ton". editarmature.c and
transform_snap.c were complex to merge. Martin, please check?
* Game engine compiles and links again here for scons/make/cmake
(player still fails to link).
* Added GUI and fixed bugs in the Cycles Modifier. This replaces the old Cyclic Extrapolation settings, giving more fine-grained control over the results. You can now specify whether the keyframes are repeated before and/or after the range independently, also, the maximum number of cycles on either side can be controlled.
* TODO: it would be nice to have the last value held for cyclic+offset.
* Deleting modifiers now works
* Finished code for Expanded Polynomial and Factorised Polynomial UI's.
* Started UI code for 'Builtin Function' mode. There are still 4 controls to add there to use something other than simple mapping
* Finished/fixed up verification code for these so that values get initialised ok.
