big spacing. Not sure if it's the best solution or it should be fixed when
calculating new areas.
It'll be cool if somebody else familiar with this area will check this.
- Added option "Fixed Texture" to the UI. Because of strange reason,
this feature was implemented but hidden from users.
Would be cool, if somebody familiar with 2d texture paiting check.
- Fixed some issues in existing code of fixed texture paiting.
It now handles brush radius and curve correct.
- Also fixed issue with paiting with texture from node tree - it used
to be painted with regular brush color instead of texture.
- rename rna collection structs Main prefix to BlendData: eg, MainObjects --> BlendDataObjects
- printing python collection now prints its type (when available)
- renamed shadowed vars in bpy_rna.c.
- when making functions static I also made debugging/test functions static, reverse and add definitions to headers instead.
- use NULL rather then 0 where possible (makes code & function calls more readable IMHO).
- set static variables and functions (exposed some unused vars/funcs).
- use func(void) rather then func() for definitions.
Manually disable jitter usage for anchored and drag dot brush stroke metdhods.
Jitter slider is hidden in UI for this strokes so users can't set it to 0 by hand
and even if this slider would be visible in UI jitter gives wierd result for
this stroke methods.
the brush system matches the brush mode with the object mode, but this doesn't work for 2D image view paint.
since the poll() function doesnt have access to the context, for now just check if no paint modes are active, default to texture paint.
- 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.
Fixed by adding a 'slope' parameter to curvemap_reset() to mirror curve presets around Y axis.
Also removed curve preset with 'random' icon, wasn't doing what it looked like it should,
this was intended only for hue correct node anyway.
Added a brush reset operator so that a user won't need to reload the default blend to get back default brush settings
* New brush.reset operator, resets a brush based on the currently-selected tool
* Added UI button in the tools panel
TODO:
* Only resets sculpt brushes right now, other paint modes should be added
* Sculpt polish tool exists only as a Brush, not as a tool; I'd suggest we make it a tool so it can be reset to defaults too
More icon work
* Added icon defines for all the brushes
* Load all the brush icons after loading regular Blender icons
* Added the brush icons to their respective tool enums in RNA
* Fixed a couple unused-variable warnings
* Fix: unify strength and size did work consistently with other paint modes
* Fix: If [ and ] keys were used to resize a brush it was not possible to increase the size of the brush if it went under 10 pixels
* Fix: Made interpretation of brush size consistent across all modes, Texture/Image paint interpreted brush size as the diameter while all the other modes interpret it as radius
* Fix: The default spacing for vertex paint brushes was 3%, should be 10%
* Fix: due to fixes to unified strength, re-enabled 'Unify Size' by default
* Fix: Unified size and strength were stored in UserPrefs, moved this to ToolSettings
* Fix: The setting of pressure sensitivity was not unified when strength or size were unified. Now the appropriate pressure sensitivity setting is also unified across all brushes when corresponding unification option is selected
* Fix: When using [ and ] to resize the brush it didn't immediately redraw
* Fix: fkey resizing/"re-strength-ing" was not working consistently accross all paint modes due to only sculpt mode having full support for unified size and strength, now it works properly.
* Fix: other paint modes did expose the ability to have a custom brush colors, so I added the small bit of code to allow it. Note: I made all of the other paint mode brushes white. Note2: Actually, probably want to make the paint modes use the selected color for painting instead of a constant brush color.
* I had removed OPTYPE_REGISTER from some Sculpt/Paint operators but in this commit I add them back. I'm not completely sure what this option does so I don't want to disturb it for now.
* Default icons can be selected from a menu
* Option to make a custom icon from a file is present but the UI is disabled because of a mysterious crash
* New startup.blend that has the appropriate icons selected
* First, try to load the file from the given filename. This is either absolute or relative to the current .blend
* If file is found using the given filename directly then look for the file in the datafiles/brushicons directory (local, user, or system).
* Note: This commit does not update the .blend to reference the default icons
* Note: This commit does not make sure that the build system copies the default icons to the 2.52/datafiles/brushicons directory
See the bugreport comments for full breakdown of the fix.

The change in brush.c is to get blender compiling again, after my previous commit which tried to fix a compiler warning related to this (but in the header file instead).
This changes how textures are accessed from Brushes, with the intention of simplifying
the workflow, and reducing the amount of clicking. Rather than the previous texture slots
(which didn't work as a stack anyway), brushes now have a single texture linked. Rather
than taking time having to set up your slots in advance, you can now select and change
textures directly as you sculpt/paint on the fly. For complex brushes, node textures can
be used, or for fast access, it's easy to make a duplicate of your brush with the texture
you like and assign a hotkey.
Brush textures can now be chosen from a new Textures panel in the brush tool
properties - click on the thumbnail to open a texture selector. This is done using a new
variation on the ID template - the number of rows and columns to display in the popup
can be customised in the UI scripts.
* Added tablet pressure support (size/strength) for weight paint and vertex paint
* Added tablet eraser support for weight paint and vertex paint (inverts the effect of the current tool)
* Removed the old 'soft' option, now weight paint and vertex paint use the influence curve
* Made the default brush use a smooth influence curve, rather than sharp
* Convert all code to use new functions.
* Branch maintainers may want to skip this commit, and run this
conversion script instead, if they use a lot of math functions
in new code:
http://www.pasteall.org/9052/python
* Draw/Inflate/Layer now keep working on the original mesh coordinates and
normals from when the stroke started. This helps avoid the mesh blowing
up, but can still be better. The old behavior is still available as
"Accumulate" in the UI.
* This requires some more memory usage for the BVH, would like to find a
way to avoid that.
* Smooth falloff is now the default.
* Spacing is now enabled by default, with a value of 7.5.
* Anchored now stores normals per node to save some memory.
* Sculpting, normal update and bounding box code is now multithreaded
using OpenMP.
* Fix a number of update issues: normals on node boundaries, outdated
bounding boxes, partial redraw, .. . There's probably still a few
left, but should be better now.
* Clicking once now does a single paint instead of two (was also
painting on mouse up event).
* Smooth shading now is enabled for the full mesh when the first face
uses it (so it can be tested at least).
Implementation Notes:
* PBVH search can now be done either using a callback or bt gathering the
nodes in an array. The latter makes multithreading with OpenMP easier.
* Normals update code is now inside PBVH, was doing it per node before but
should do all faces first and only then vertices.
* Instead of using search modes + 1 modified flag, now nodes get 4 flags
to indicate what needs to be updated for them, found that this makes it
easier for me to understand the code and fix update bugs.
* PBVHNode is now exposed as an abstract type, I think this makes it more
clear what is happening than having it's data passed as part of callback
functions.
* Active_verts list was replaced by looping over nodes and the vertices
inside them. However the grab brush still uses the active_verts system,
will fix that later.
* Some micro-optimizations, like avoiding a few multiplications/divisions,
using local variables instead of pointers, or looping over fewer vertices
to update the bounding boxes.
