Fixes small precision problems.

In some cases objects might have rigid bodies but aren't in the rigid
body group, just add objects to the group then.
Also allow changing the rigid body type by using the add acive/passive
buttons. This avoids having to remove objects just to change type.
|
|
Remore group notifiers, they're already sent by add/remove group operators.
Add pointcache notifiers.
Fixes UI not being updated properly in some cases.

Fixes cache not being invalidated when using change collision shape and
calculate mass operators.

Issue was caused by couple of circumstances:
- Normal Map node requires tesselated faces to compute tangent space
- All temporary meshes needed for Cycles export were adding to G.main
- Undo pushes would temporary set meshes tessfaces to NULL
- Moving node will cause undo push and tree re-evaluate fr preview
All this leads to threading conflict between preview render and undo
system.
Solved it in way that all temporary meshes are adding to that exact
Main which was passed to Cycles via BlendData. This required couple
of mechanic changes like adding extra parameter to *_add() functions
and adding some *_ex() functions to make it possible RNA adds objects
to Main passed to new() RNA function.
This was tricky to pass Main to RNA function and IMO that's not so
nice to pass main to function, so ended up with such decision:
- Object.to_mesh() will add temp mesh to G.main
- Added Main.meshes.new_from_object() which does the same as to_mesh,
but adds temporary mesh to specified Main.
So now all temporary meshes needed for preview render would be added
to preview_main which does not conflict with undo pushes.
Viewport render shall not be an issue because object sync happens from
main thread in this case.
It could be some issues with final render, but that's not so much
likely to happen, so shall be fine.
Thanks to Brecht for review!

This modules does not depend on any blender-specific data
structures or algorithms and due to our policy better be
placed to intern/
Shall be no functional changes, tested CMake and SCons on
Linux, hopefully other platforms will work as well.
P.S. SVN history shall be preserved for the files.

Also generate rigid body constraint types in py bullet code from RNA enum values (simpler than having to sync the code when something is changed here!).
Side note: RNA API about icons still needs to expose icons for enum values, and conversion funcs between icon_name and icon_value!

MEM_recallocN() doesn't allocate memory when used on a null pointer.
Just revert commit since there is no real benefit to using
MEM_recallocN() in this case.

Now all add/remove operators for rigid body objects and constraints
automatically add objects to the appropriate groups and create groups if they
don't exist yet.
This makes handling rigid bodies easier but doesn't take away functionality.
If users want to handle groups manually they just need to create them before
adding any objects.
The previous behaviour was confusing and was even considered to be a bug since
clicking on rigid body in the physics tab seemed to do nothing.

Constraints connect two rigid bodies.
Depending on which constraint is used different degrees of freedom
are limited, e.g. a hinge constraint only allows the objects to rotate
around a common axis.
Constraints are implemented as individual objects and bahave similar to
rigid bodies in terms of adding/removing/validating.
The position and orientation of the constraint object is the pivot point
of the constraint.
Constraints have their own group in the rigid body world.
To make connecting rigid bodies easier, there is a "Connect" operator that
creates an empty objects with a rigid body constraint connecting the selected
objects to active.
Currently the following constraints are implemented:
* Fixed
* Point
* Hinge
* Slider
* Piston
* Generic
Note: constraint limits aren't animatable yet).

Add operators to add/remove rigid body world and objects.
Add UI scripts.
The rigid body simulation works on scene level and overrides the
position/orientation of rigid bodies when active.
It does not deform meshes or generate data so there is no modifier.
Usage:
* Add rigid body world in the scene tab
* Create a group
* Add objects to the group
* Assign group to the rigid body world
* Play animation
For convenience the rigid body tools operators in the tools panel of the 3d view
will add a world, group and add objects to the group automatically so you only have
to press one button to add/remove rigid bodies to the simulation.
Part of GSoC 2010 and 2012.

Particle combing didn't always respond as expected. The combed effect was
depending on the center of object in view, instead of on the center of
selected hairs. That made combing in certain close ups impossible.
Same was actually true for transform tools for hairs!
And even worse - there was an optimize break in calculating center
which wasn't true even. Causing centers for transform to fail similar
in other cases.
|
|
Issue was caused by disabled particle system modifier, now connect hair
will check on that and give an error message if modifier is disabled.

caused by not projecting points behind the perspective view,
even though this worked in 2.64 the values were flipped (rotating direction was reversed and the center point was flipped).
added V3D_PROJ_TEST_CLIP_NEAR, when omitted ED_view3d_project_*** will project points from behind a perspective view plane.

Also fix:
- Fluid simulation was always lagging 1 frame behind: E.g. the 250th frame in blender showed 249th frame of the fluid simulation.
Change:
- Animated enabled/disabled property only gets counted as "on" if value >= 1
Note that this bugfix should solve many problems with timings of animated fluid sim properties.
