Think global, act local!
The old favorite G.scene gone! Man... that took almost 2 days.
Also removed G.curscreen and G.edbo.
Not everything could get solved; here's some notes.
- modifiers now store current scene in ModifierData. This is not
meant for permanent, but it can probably stick there until we
cleaned the anim system and depsgraph to cope better with
timing issues.
- Game engine G.scene should become an argument for staring it.
Didn't solve this yet.
- Texture nodes should get scene cfra, but the current implementation
is too tightly wrapped to do it easily.
*removed commented code about the dropped shrinkwrap options
*Removed references to "cut plane", "limitMesh".. its now called "auxiliar target"
*Added option to shrinkwrap over an selected axis
*"Normal projection" mode is now called "projection" since it can now project over "normal, and any combination X, Y, Z"
*the options "remove faces", "merge" points were removed
*made shrinkwrap work with CVs (curves and nurbs surfaces)
*cleanup shrinkwrap code.. (removed bruteforces and raytree methods)
*Made nearest surface also use "quad" bvh tree (instead of splitting quads in 2 bvh nodes).
Again that leaded to improvements in build and query time.
*BLI_bvhtree_find_nearest api is now following the same concept as BLI_bvhtree_ray_cast
removed code relative to bvhtree_from_mesh_tris.
Changed code to remove faces (now quad faces that got one vertice projected are turned on tri)
Merge option is still not very usefull since shrinkwrap does not yet moves unprojected vertices
+added option to remove faces where all vertices got unprojected
Nearest surface point
+15% faster closest point on point-tri function
(archived by projecting the point on tri-plane and solving the problem on 2D)
(its still using bruteforce on triangles.. I'll add the right data structure later)
+vertex weights supported
+target object now saves to file: load/save works :)
for now simple moves objects vertexs to the nearest vertexs on target object
(so that I can test if its working correctly with the modifier API)
