* <s>Remove ss->fmap need for normals</s><br />
* <s>Don't use active verts list but nodes</s><br />
** <s>Grab brush still needs to be converted</s><br />
* <s>Separate undo stack for sculpt mode</s><br />
* <s>Only create DM origindex layer when needed.</s><br />
* <s>Only create sculpt face normals when needed.</s><br />
* <s>Store anchored original normals per node</s><br />
* <s>Store multires displacements outside .blend in a texture file</s><br />
* <s>Use more compact multires/subsurf DM</s><br />
* Remove ss->fmap need for smooth brush<br />
<br />
Drawing<br />
* <s>Show multires base resolution when navigating view</s><br />
* <s>Sometimes wrong partial redraw rect is generated, messing up window draw</s><br />
* <s>Sometimes normals are not updated in some places (on node boundaries?)</s><br />
* <s>Fall back to vertex arrays if VBO allocation fails.</s><br />
* <s>Make sculpt VBOs work with object mode VBOs, currently mesh disappears.</s><br />
* Support multiple partial redraws (for symmetry)<br />
* PBVH drawing working for more draw modes<br />
* Respect per face smooth/flat shading flags in sculpt mode.<br />
* Some graphics card still have [http://www.vimeo.com/7832867 issues with partial redraw].<br />
<br />
Multires<br />
* <s>Change storage format so we have n grids for a polygon with n verts</s><br />
* <s>Store multires displacements outside .blend</s><br />
* <s>Add separate render level</s><br />
* <s>Add separate sculpt level</s><br />
* <s>Simple subdiv does not work well currently.</s><br />
* <s>Make smooth brush work again for multires.</s><br />
* Multires could do partial updates based on what changed when changing levels<br />
* Make layer brush work again for multires.<br />
* Grab brush can tear gaps in mesh sometimes (how to reproduce?).<br />
* Restore old multires conversion code.<br />
* Make interpolation work again in edit mode.<br />
* Brush sometimes punches through to the other side with multires (need intersection epsilon?).<br />
<br />
Performance<br />
* <s>Multithreading for sculpting</s><br />
* <s>Multithreading for multires/subsurf code.</s><br />
* <s>Move PBVH to DM</s><br />
* <s>Reduce PBVH build time</s><br />
* <s>Take advantage of subsurf/multires structure for PBVH build</s><br />
* Low level optimizations for functions like brush drawing or normal updates (e.g. SSE)<br />
* When sculpting can't keep up with the user, it would be good if Blender did not lock up but rather kept redrawing the brush and show intermediate results. A simple time limit to force an extra redraw + delay stroke updates could solve most cases.<br />
<br />
Tools<br />
* <s>Partial Refresh and Show Brush seem to not do anything</s><br />
* <s>Clicking outside of the mesh seems to lead to getting stuck in sculpting somehow.</s><br />
* <s>Make default falloff curve smooth instead of sharp (also nicer for paint).</s><br />
* <s>Shortcut keys for switching multires level</s><br />
* Falloff curve is not smooth enough. Could use bspline rather than cardinal interpolation (but only internally so user doesn't see it doesn't exactly go through points).<br />
* Support maximum brush strength clamping, instead of always adding on top like airbrush?<br />
* Hiding could use editmode flags? (especially for multires)<br />
* Brush datablock management:<br />
** One brush datablock for each type with own strength size<br />
** Nicer list widget for browsing brushes, with previews?<br />
** Shortcut keys for brushes<br />
<br />
External File Storage<br />
* <s>Integrate better with object remove/duplicate/.. .<s/><br />
* <s>Make it work with library linking.</s><br />
* Free memory after exiting lowering levels (e.g. exiting sculpt).<br />
* Support loading only lower levels.<br />
<br />
Other<br />
* <s>Make sculpting shape keys work.</s></div>wiki>Brecht
