* Mesh.add_geometry, Mesh.update and make indices editable. This
is without checking if they are valid still, no time now to
implement this.
* Also fix warnings in rna_ui.c, and a bug in CDDM_calc_edges.
Example code:
co = [0.0, 0.0, 0.0] + [1.0, 0.0, 0.0] + [0.0, 1.0, 0.0] + [1.0, 1.0, 0.0]
faces = [0, 1, 2, 0] + [1, 3, 2, 0]
mesh.add_geometry(4, 0, 2)
mesh.verts.foreach_set("co", co)
mesh.faces.foreach_set("verts", faces)
mesh.update()
(though it's not completely feature-complete yet).
I ported over the remove doubles code from the
old bmesh branch for this, and split it into two
bmops, "Weld Verts" and "Remove Doubles".
Weld verts welds specific verts together, while remove
doubles finds doubles and welds them.
I also reverted the hotkey change I made earlier.
Start of planned DerivedMesh refactoring. The mface
interfaces in DerivedMesh have been renamed to reflect
their new status as tesselated face interfaces (rather
then the primary ones, which are now stored in mpolys).
short review: mpolys store "primary" face data, while
mfaces store the tesselated form of the mesh (generally
as triangles). mpolys are defined by mloops, and each
mpoly defines a range of loops it "owns" in the main
mloop array.
I've also added basic read-only face iterators, which
are implemented for CDDM, ccgsubsurf, and the bmeditmesh
derivedmesh. Since faces are now variable-length things,
trying to implement the same interface as mfaces would not
have worked well (especially since faces are stored as
an mpoly + a range of mloops).
I figure first we can evaluate these simple read-only
face iterators, then decide if a) we like using iterators
in DerivedMesh, b) how much of it should use them, and c)
if we want write-capable iterators.
I plan to write official docs on this design after I get
it more stable; I'm committing now because there's a rather
lot of changes, and I might do a merge soon.
Attempt to make multires updating a little cleaner by
assuming that no update needs to be performed, and only
doing the update when the modified flag is set (either
by sculpting or using some other tool that needs an update.)
soc-2008-nicholasbishop branch.
Note: any old code with multires_test() or multires_level1_test() can
just be deleted, not needed by the multires modifier.
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.
* subsurf code had a lot of unused variables, removed these where they are obviously not needed. commented if they could be useful later.
* some variables declorations hide existing variables (many of these left), but fixed some that could cause confusion.
* removed unused vars
* obscure python memory leak with colorband.
* make_sample_tables had a loop running wasnt used.
* if 0'd functions in arithb.c that are not used yet.
* made many functions static
the features that are needed to run the game. Compile tested with
scons, make, but not cmake, that seems to have an issue not related
to these changes. The changes include:
* GLSL support in the viewport and game engine, enable in the game
menu in textured draw mode.
* Synced and merged part of the duplicated blender and gameengine/
gameplayer drawing code.
* Further refactoring of game engine drawing code, especially mesh
storage changed a lot.
* Optimizations in game engine armatures to avoid recomputations.
* A python function to get the framerate estimate in game.
* An option take object color into account in materials.
* An option to restrict shadow casters to a lamp's layers.
* Increase from 10 to 18 texture slots for materials, lamps, word.
An extra texture slot shows up once the last slot is used.
* Memory limit for undo, not enabled by default yet because it
needs the .B.blend to be changed.
* Multiple undo for image painting.
* An offset for dupligroups, so not all objects in a group have to
be at the origin.
----------------------------------
Small fix to derivedmesh for snapping: don't create origindex for
editmesh derivedmesh since it's not being filled correct anyway.
The following is a commit of Levi Schooley's bevel code and
the bmesh library it depends on. The current editmode bevel has
been replaced with a new per edge bevel function. Vertex beveling is
also availible.
To set weights for the modifier to use, use the ctrl-shift-e shortcut on either edges
or vertices.
Recursive beveling is turned of for the time being.
=========
Merge of the famous particle patch by Janne Karhu, a full rewrite
of the Blender particle system. This includes:
- Emitter, Hair and Reactor particle types.
- Newtonian, Keyed and Boids physics.
- Various particle visualisation and rendering types.
- Vertex group and texture control for various properties.
- Interpolated child particles from parents.
- Hair editing with combing, growing, cutting, .. .
- Explode modifier.
- Harmonic, Magnetic fields, and multiple falloff types.
.. and lots of other things, some more info is here:
http://wiki.blender.org/index.php/BlenderDev/Particles_Rewritehttp://wiki.blender.org/index.php/BlenderDev/Particles_Rewrite_Doc
The new particle system cannot be backwards compatible. Old particle
systems are being converted to the new system, but will require
tweaking to get them looking the same as before.
Point Cache
===========
The new system to replace manual baking, based on automatic caching
on disk. This is currently used by softbodies and the particle system.
See the Cache API section on:
http://wiki.blender.org/index.php/BlenderDev/PhysicsSprint
Documentation
=============
These new features still need good docs for the release logs, help
for this is appreciated.
using mface->flag for both.
Also found that the cdDM_drawMappedFaces and cdDM_drawFacesTex_common could get normals mixed up when rendering hidden faces. because hidden/invisible faces used continue without advancing to the next normal.
- edges are generated from verse faces
- no support for lose edge!
- informations about edges aren't sent to verse server (other applications
can't share edges with blender)
- better sending/receiving vertex position
These can be created and deleted in the Mesh panel in the same place as
before. There is always one active UV and vertex color layer, that is
edited and displayed.
Important things to do:
- Render engine, material support
- Multires and NMesh now lose non active layers
Also CustomData changes to support muliple layers of the same type, and
changes to layer allocation, updated documentation is here:
http://mediawiki.blender.org/index.php/BlenderDev/BlenderArchitecture/CustomData
- Curve/Nurbs/Font/MBall now all draw arrays.
- had to flip abgr to rgba in shaded drawing
- Mesh drawing can't be easily done; the indices for faces are not in
in one chunk. Also need a way to gether trias/quads, per material.
Speedup results are mixed. Something between 2-4 times. Especially for
text it seems to help.
All data layers, including MVert/MEdge/MFace, are now managed as custom
data layers. The pointers like Mesh.mvert, Mesh.dvert or Mesh.mcol are
still used of course, but allocating, copying or freeing these arrays
should be done through the CustomData API.
Work in progress documentation on this is here:
http://mediawiki.blender.org/index.php/BlenderDev/BlenderArchitecture/CustomData
Replaced TFace by MTFace:
This is the same struct, except that it does not contain color, that now
always stays separated in MCol. This was not a good design decision to
begin with, and it is needed for adding multiple color layers later. Note
that this does mean older Blender versions will not be able to read UV
coordinates from the next release, due to an SDNA limitation.
Removed DispListMesh:
This now fully replaced by DerivedMesh. To provide access to arrays of
vertices, edges and faces, like DispListMesh does. The semantics of the
DerivedMesh.getVertArray() and similar functions were changed to return
a pointer to an array if one exists, or otherwise allocate a temporary
one. On releasing the DerivedMesh, this temporary array will be removed
automatically.
Removed ssDM and meshDM DerivedMesh backends:
The ssDM backend was for DispListMesh, so that became obsolete automatically.
The meshDM backend was replaced by the custom data backend, that now figures
out which layers need to be modified, and only duplicates those.
This changes code in many places, and overall removes 2514 lines of code.
So, there's a good chance this might break some stuff, although I've been
testing it for a few days now. The good news is, adding multiple color and
uv layers should now become easy.
now, others can be added later (sticky, shape keys). Beside one small fix
for knife exact vertex group interpolation, is intended to work the same
as before.
Also fixes bug #5200, related to editmode undo and vertex groups. And
corrects the editmode to faceselect mode selection conversion, that was
broken in a previous commit.
the CustomData module from the modifier stack rewrite, but with additions
to make it also usable in edit mode. Some of the datatypes from that
module were move to a DNA header file, they are not saved to file now, but
will be soon.
The only code that wasn't abstracted is the uv collapse / merging code. It
is rather complicated, will look into that in the future.
There should be no user level changes.
