On file save the mesh gets loads from the editmesh but the derived mesh caches
wer not cleared. This usually happens through the depsgraph but it needs to be
done manually here. Most changes are some refactoring to deduplicate derived
mesh freeing code.
This functios are declared in BKE_paint.h header and using
SculptSession structure which is also declared there.
Anyway, does not make sense such a splitting of header and
implementation files, better be consistent here.
Allow separate control for tex/mask/cursor overlay. This commit implements
separate overlays for mask textures and cursor curves. The user can turn on
and off separate parts of the overlay by using the appropriate widgets.
The cursor overlay widgets are located at the tool selection panel
Also fixed alpha masks not getting correctly masked and mask texture mapping
not having the correct update callback
* Fix precision overflow issue with overlay previews,
* Expose alpha mask mapping to UI (still not functional but coming soon).
* More overlay refactoring:
Overlay now does minimal checking for texture refresh.
Instead, we now have invalidation flags to set an aspect of the brush
overlay as invalid. This is necessary because this way we will be able to
separate and preview different brush attributes on the overlays, using
different textures:
These attributes/aspects are:
Primary texture (main texture for sculpt, vertex, imapaint)
Secondary texture (mask/alpha texture for imapaint)
Cursor texture (cursor texture. It involves brush strength and curves)
Modified the relevant RNA property update functions and C update callback
functions to call the relevant cursor invalidation functions instead
of checking every frame for multiple properties.
Properties that affect this are:
Image changes, if image is used by current brush,
Texture slot changes, similarly
Curve changes,
Object mode change invalidates the cursor
Paint tool change invalidates the cursor.
These changes give slightly more invalidation cases than simply
comparing the relevant properties each frame, but these do not occur in
performance critical moments and it's a much more elegant system than
adding more variables to check per frame each time we add something on
the system.
ALERT! POSSIBLE BREAKING COMMIT, ESPECIALLY FOR SCULPT!
Separate the sculpt sampling function so that it can be reused
from other paint systems. This includes updating of the relevant
coordinates for anchored and rake style brushes, which are now
being updated as part of the stroke system.
I left only code for area-style brush texture mapping in sculpt
code, since it requires a few data structures not present on other
paint systems.
This commit makes it almost as easy to support rake on other systems as
exposing the python UI for it. Also it makes it totally possible to
have texture painting capabilities in vertex paint too :) These commits
will follow very soon.
Also, even if I did my best to keep the code from breaking, (even fixed a
leftover bug from coordinate changes) this is a big change. Please test!
Issue was caused by couple of circumstances:
- Normal Map node requires tesselated faces to compute tangent space
- All temporary meshes needed for Cycles export were adding to G.main
- Undo pushes would temporary set meshes tessfaces to NULL
- Moving node will cause undo push and tree re-evaluate fr preview
All this leads to threading conflict between preview render and undo
system.
Solved it in way that all temporary meshes are adding to that exact
Main which was passed to Cycles via BlendData. This required couple
of mechanic changes like adding extra parameter to *_add() functions
and adding some *_ex() functions to make it possible RNA adds objects
to Main passed to new() RNA function.
This was tricky to pass Main to RNA function and IMO that's not so
nice to pass main to function, so ended up with such decision:
- Object.to_mesh() will add temp mesh to G.main
- Added Main.meshes.new_from_object() which does the same as to_mesh,
but adds temporary mesh to specified Main.
So now all temporary meshes needed for preview render would be added
to preview_main which does not conflict with undo pushes.
Viewport render shall not be an issue because object sync happens from
main thread in this case.
It could be some issues with final render, but that's not so much
likely to happen, so shall be fine.
Thanks to Brecht for review!
Moved the GPU function gpu_bmesh_face_visible() to BKE_paint and
inverted the test to match equivalent tests for other mesh types:
paint_is_bmesh_face_hidden().
Changed BKE_pbvh_bmesh_node_save_orig() to not save hidden faces into
the triangle array.
Modified the non-use-original branch of pbvh_bmesh_node_raycast() to
skip hidden faces.
Fixes bug #33914:
projects.blender.org/tracker/index.php?func=detail&aid=33914&group_id=9&atid=498
Some operators like curve presets, color sample and some more were using object's
mode to distinguish in which mode user is currently painting. Such approach fails
in cases when there's paint mode active in 3D viewport and Image Editor.
Changed logic here to use some context's state like active space which helps
distinguishing current paint mode more accurate.
Ported all areas which uses paint_get_active() to new paint_get_active_from_context().
There're still some calls to paint_get_active(), but that shouldn't be harmful due
to that places indeed have object's mode as priority when getting paint mode.
=========================
Documentation: http://wiki.blender.org/index.php/User:Psy-Fi/UV_Tools
Major features include:
*16 bit image support in viewport
*Subsurf aware unwrapping
*Smart Stitch(snap/rotate islands, preview, middlepoint/endpoint stitching)
*Seams from islands tool (marks seams and sharp, depending on settings)
*Uv Sculpting(Grab/Pinch/Rotate)
All tools are complete apart from stitching that is considered stable but with an extra edge mode under development(will be in soc-2011-onion-uv-tools).
Normalize, Normalize All, Invert, Clean, and Levels.
Face mask and vertex select/mask are now mutually exclusive options.
Went ahead and allowed vertex selection support and masking for vertex paint.
Weight Paint Vertex Select tweaked to act like edit mode's select and Circle select was added, but clipping is not working properly for either.
Select all was added too, but to the Q key until I look into overriding A's select all bones.
The select vertices checkbox was moved to the header, but it does not force face select mask to turn off yet--and it doesn't have the correct icon.
There will definitely be an update tomorrow to fix the problems with all or most of the issues.
- removed deprecated bitmap arg from IMB_allocImBuf (plugins will need updating).
- mostly tagged UNUSED() since some of these functions look like they may need to have the arguments used later.
- remove brush array for each Paint struct, just use a single brush pointer.
- removed rna function based template filtering.
- filter brushes using a flag on the brush and the pointer poll function.
- set the brushes using a new operator WM_OT_context_set_id().
TODO
- remake startup.blend, currently brush groupings are lost.
- rewrite WM_OT_context_set_id() to use rna introspection.
