* 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.
- remove falloff setting now the curve is used.
- bugfix for airbrush & tablet, with no movement it would assume 1.0 pressure.
- rna, use the use_* prefix for brush options.
* Changed the non-projection paint code to use the brush falloff curve, rather than a predefined falloff. This makes non-projection painting in the 3d view, and image editor painting much more consistent with other brush usage.
* Added UI for brush stroke. Contains for now spacing and smooth stroke
* Removed Sculpt UI for airbrush -- doesn't do anything in sculpt mode
* Improved smooth stroke by using float instead of int precision, so smooth stroke is even smoother now
* Added a new Paint type in scene DNA. This is now the base struct for Sculpt.
* The Paint type contains a list of Brushes, you can add or remove these much like material and texture slots.
* Modified the UI for the new Paint type, now shows the list of brushes active for this mode
* Added a New Brush operator, shows in the UI as a list of brush tool types to add
* Made the sculpt tool property UI smaller and not expanded, expectation is that we will have a number of preset brushes that will cover the basic sculpt brush types
TODO:
* Vertex paint, weight paint, texture paint need to be converted to this system next
* Add brush presets to the default blend
* Made texture paint object-localized too.
Note for Brecht: gpu_draw.c had three uses of G_TEXTUREPAINT that I was not able to cleanly fix, so commented out for now. Can you take a look and see what should be done here?
* Weightpaint is now object-local like sculpt and vertexpaint.
* Fixed a bug spotted by DingTo, going from editmode to sculptmode didn't fully leave editmode
* Made sculpt mode local to object.
* This also fixes loading files from 2.4x saved in sculptmode
Touched a lot of things here, let me know if anything breaks
TODO:
* The other paint modes should be converted as well
* Moved the brush texture settings to MTex/TextureSlot. The mapping settings now show up in the texture panel, pretty much like they do for textures used with materials.
TODO:
* Tiled mode should not show Z size setting
* Add a locked mode so that texture size can be changed uniformly like in 2.4x
Assorted smaller fixes:
- Fix: modal keymaps for editmode in view3d were not set again
when you copy areas or go fullscreen.
- Improved "redo last op" (F6) to search back in history for
a redoable operator. Operator also used wrong pupmenu type.
- On creating new FCurve editor, the channel rainbow colors are
set correct.
- EditMesh: fixed code for Spin/Screw, correct props, init and
error reporting. (Spin hotkey ALT+R temporary)
- recompiled all to check for uninitialized variable warnings.
(compile flag should be -O for this). Fixed some proto's.
* Means that full object recalc isn't done, so multires works more as expected now
* Moved mesh element cache back to sculpt session (from sculpt cache), really makes more sense there
