More globals discovered; lattice deform stored static
deform array and a matrix. Tsk!
|
|
From the anti-globalization department:
G.obedit terminated!
Wherever possible, use CTX_data_edit_object(C) to get this
now. It's stored in scene now, and the screen context has
it defined.

In a quick glance: (temp image)
http://www.blender.org/bf/rt.png
Main reason is that Lattices are useful a lot for Armature deformation.
Lattices just provide much more precise and interesting control. However,
with only bone envelopes it's very hard to use.
Working with Lattice vertex groups is nearly identical to Mesh:
- on CTRL+P 'make parent' you can choose the deform option now
- In editmode, the buttons to control vertex groups are available
- In outliner you can select vertexgroups too
- Deforming Lattices with Armatures has all options as for Mesh now.
Note:
- No WeightPaint has been added yet. To compensate, the editmode
drawing for a Lattice with vertex group shows weight values for the active
vertex group.
- Lattice editmode doesn't undo/redo weight editing yet.
- Softbody for Lattice still uses own vertex weights
Implementation notes:
- derivedmesh weight_to_rgb() is now exported to drawobject.c
- been doing cleanups in code (order of includes, var declarations, etc)
- weightpaint button handling now is generic
I've checked on Brecht's proposal for Custom Element data;
http://mediawiki.blender.org/index.php/BlenderDev/CustomElementData
It could have been used, but that would mean the existing code for
vertexgroup handling and armature deform couldn't be re-used. I guess this
is really a later todo.

- new feature, twiddled with lattice resizing to try to maintain
existing vertex changes... much nicer than just resetting the
lattice if you decide you need more detail in the lattice.
- modifiers work with lattices now. yes, that does mean you
can make a chain of lattices effecting each other 8 miles
long.
- some cleanup of softbody code, was rather splintered and call
path was twisted and confusing. reworked main object step
routine to do things in a more obvious and consistent manner
and without duplicate code
- added ob->softflag OB_SB_RESET instead of sbObjectReset
call
- modifier changes reset softbody now
- moved curve_getVertexCos/curve_applyVertexCos into curve.c
- update curve modifier eval to work with virtual modifiers
- update modifier apply to work with curves/surfs
- update make parent to also recalc object data
NOTE: Although you can turn SB on for curve/font objects at the
moment it doesn't really work because they call deform in
multiple steps and this confuses SB. Not sure how to deal with
atm.

different objects shouldn't share flags this way (still sharing of
other mesh flags in renderer... ickity pickity, but I'm not fixing now)
- removed some unnecessary uses of DNA_mesh_types.h

So we should be all set now :)

(adding)
#ifdef HAVE_CONFIG_H
#include <config.h>
#endif
also the Makefile.in's were from previous patch adding
the system depend stuff to configure.ac

little minor spacing issues.
