weighted normals as the render engine, and the render engine will copy
normals from the mesh rather than always recalculating them.
Subsurf/multires still use regular vertex normals, but they are expected
to be sufficiently high resolution to not need this.
This means that normal maps displayed in the viewport actually match the
render engine exactly and don't have artifacts due to this discrepancy.
It of course also avoids unexpected surprises where your render normals
look different than your viewport normals.
Subversion bumped to 4 for version patch to recalculate normals.
Patch by Morten Mikkelsen, with some small changes.

the two files mikktspace.h and mikktspace.c. These are standalone files
which can be redistributed into any other application and regenerate the
same tangent spaces. The implementation is independent of the ordering
of faces and the vertex ordering of faces.

==========================
Removed limitation of armatured-only objects for sculpting -- now all
deformation modifiers are allowed in sculpt mode. Use crazyspace corrections
like from transformation modules was used to support all deformation modifiers.
Internal change: all crazyspace-related functions were noved to crazyspace.c
P.S. Brush could make quite unexpected deformation for meshes which are
deformed in specified way. Got patch for this and discussing with Brecht
if it's really needed or maybe it could be done in better way.
|
|
Some naming changes to make naming more uniform. No functional changes.
It's necessery for further crazyspace changes and improvenments.
|
|
Used a crazyspace approach (like in edit mode), but only modifiers with
deformMatricies are allowed atm (currently shapekeys and armature modifiers only).
All the rest modifiers had an warning message that they aren't applied because
of sculpt mode. Deformation of multires is also unsupported.
With all this restictions users will always see the actual "layer" (or maybe
mesh state would be more correct word) they are sculpting on.
Internal changes:
- All modifiers could have deformMatricies callback (the same as deformMatriciesEM but
for non-edit mode usage)
- Added function to build crazyspace for sculpting (sculpt_get_deform_matrices), but it
could be generalized for usage in other painting modes (particle edit mode, i.e)
Todo:
- Implement crazyspace correction to support all kinds of deformation modifiers
- Maybe deformation of multires isn't so difficult?
- And maybe we could avoid extra bad-level-stub for ED_sculpt_modifiers_changed
without code duplicating?

physically, fixes bug #24942 and #25286.
Support for physics is done by skiping the modifiers that
don't support mapping to original mesh. This mapping is
required to report the hit polygon to the application
by the rayCast() function.
Support for graphics is done by using the same render
function that blender uses for the 3D view. This guantees
equal result.
Limitation: there is still a known bug if all these conditions are met:
- Display list enabled
- Old tex face with a several textures mapped to the same material
- no armature or shape keys
- active modifiers
In this case, only a part of the mesh will be rendered
with the wrong texture. To avoid this bug, use the GLSL
materials or make sure to have 1 material=1 texture in
your old tex face objects.

This is a more general problem that drawing functions would skip faces when the original index could not be found, screw result for example wasnt visible in editmode too.
Fixed by adding a material set argument to DerivedMesh->drawMappedFaces(), this was already being done in some of the other drawing functions.

basically just some things that needed to be done before trunk (and some things that needed to be started, but can be finished much later).
|
|
- vertex normals were not being flipped (though faces are)
- rim faces didnt influence edge vertex normals
apply solidify on top of solidify modifier now works correctly

Used approach with creating DerivedMesh for curves whet they've got such modifiers.
Available modifiers are: array, edge split, mirror, solidify, subsurf.

I've removed editmesh altogether (other then scanfill, which is
seperate code that happens to reuse the editmesh structures).
The compatibility layer I had written for old editmesh tools
was more trouble then it was worth, though it did help in the
early stages of this project.
There's a fair amount of breakage, and there's bunches of tools
(mostly minor ones) I need to port over still. Biggest ones are
join triangles and loop to region, and spin/screw.
This probably isn't really testable, I'll hopefully have more
work done on this soon, but might not be before next week.

levels, child particles, and shadow/SSS/AO quality.. Now also works on what
is displayed in the 3d view instead of only rendering, see panel in the scene
properties.
Most file changes were to make scene available in the isDisabled modifier
callback function.

Fix #20516: subsurf modiefier+pressing add for smoke sims results in crash.
Fix retopo not working correct on subsurf mesh.
Various deforming modifiers were not correctly taking into account that a
derivedmesh is not necessarily a CDDerivedMesh, made utility functions for
this now.

Most likely will not compile for others, I'd appreciate any build errors
and missing files reports (I can never seem to get everything committed
and all the build systems working without help).
Porting over the sculpt/multires tools was a breeze,
thanks goes to brecht for a design that didn't exclude
ngons and was easy to port.
Note that I've not tested externally-backed multires
file support yet. Also, I still need to write version
patch code for some cases.
Some notes:
* Like trunk, topological changes don't update multires right,
so e.g. subdivide will duplicate multires data on the new faces,
instead of subdividing it.
* If you set the debug value (ctrl-alt-d) to 1 it'll turn on
my experiments in speeding up sculpting on higher-res multires
meshes (but note it makes partial redraw not completely accurate).
* There's a bug where you have to go through editmode to get out
of sculpt mode, not sure if I inherited or created this myself.
|
|
* Fix #20482: grab brush + size pressure sensitivity don't work
together, disabled the pressure sensitivty for that case now.
* Fix for smooth brush messing up mesh sometimes, smooth factor
is now clamped to reasonable range.
* Fix #20449: smooth brush + mirror modifier could crash.

* Multithread parts of multires and subsurf. Only loops working on
face grid data and do no memory allocation have been multithreaded,
others would be more complicated.
* Force some CCGSubsurf functions to be inlined, gives a small overall
speedup in subsurf code.
* Fix sculpting not working correct with transformed objects.
* Fix a few cases of "spikes" on lower level multires levels. There's
still cases where it happens, usually on boundary cornders. The
problem is that in such cases the limit surfaces can be very different
from the low res surface, so the tangent space is very different too..
* Fix crash deleting multires higher levels with level set to 0.
* Fix crashes that happened sometimes when adding faces in editmode.

level when rotating/panning/zooming the viewport, and only draw the full thing
at the end, to make the viewport more interactive.
|
|
* Now uses the CCG DerivedMesh also in object mode, used to be edit mode only.
* Create CD_ORIGINDEX layer on demand, to save memory.
* Removed ss_to_cdderivedmesh function, and instead create ccgdm and then
convert that to cddm, to avoid code duplication.
* Added and implement DerivedMesh interface functions to obtain face grids.
* Store edge/face flags more memory efficient.
* Export CCGDerivedMesh struct in BKE_subsurf.h

Rather than applying the modifier to the object data, it will create a new shape
with the deformed vertices in there. Only mesh at the moment, other object
types on the todo.

* Multires sculpting appears to work now
* PBVH gets recalculated in some cases where it shouldn't, haven't looked into this yet

#ifdef'd out on release builds. also did little bit of work on subsurf. and face select can now deselect again, and fixed some other bugs with it (and subsurf).
|

issues left, and for some reason textured objs aren't displaying properly in object mode.

(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.

Notes:
* Game and sequencer RNA, and sequencer header are now out of date
a bit after changes in trunk.
* I didn't know how to port these bugfixes, most likely they are
not needed anymore.
* Fix "duplicate strip" always increase the user count for ipo.
* IPO pinning on sequencer strips was lost during Undo.

replaced with bmesh. this is not usable by any means. for those who read through this, note the design is still fairly messy in places, and fyi BMTessMesh is the replacement for EditMesh, I need to rename it to BMEditMesh.
