Also add depsgraph & physics

This assert happens all the time for character physics in debug mode.
In release mode, the assert is skipped but the code is still incorrect
although it does not cause any crash strangely.
|
|
Noticed this while looking into something else.
The change is trivial, but gives a rather nice preformance improvement,
so why not.
Theres's actually a lot one can do to improve collision performance if
one wanted to, the triangle-triangle check alone has a lot of room for
improvement.

obsolete compileflag magic

-ffast-math is evil, not sure why it was enabled...
I seems to work better on OSX but it's still not a good idea.
The SConscript for bullet is a mess, I don't understand why
we use different flags for different platforms in the first place.
Seems to be a historical artifact but I don't know enough about scons
to try and clean it up.

bullet, according cmake ( less speed penalty )
|
|
stricter to reduce speed penalty
|
|
I overlooked in cmake my fix same time changed the optimization level to 0,
so not use optimization is the real fix ( postponed for after 2.70 ).
I appears we should investigate scons anyway: compileflags does not apply to c and c++ same time as expected.

This was caused by static variables used in plNearestPoints().
For now solved by making the solvers allocated in the stack,
seems no noticeable affect on the simulation speed so far.
|
|
CXXFLAGS start empty also in “Release”
|
|
|
|
are in sync for OSX
|
|
|
|
also remove gcc 4.6 workaround, i don’t think its needed any longer.
!!! pls check if this would be right thing todo for othere OS too !!!

Fixes part of T37905, fixed constraint didn't work correctly.
|
|
|
|
Can't actually test here so hope this is enough.
|

Remove patch that has been applied upstream.
Fixes several bugs.
|
|
Remove stray BT_USE_SSE_IN_API definitions.
Was causing problems especially for 32 bit windows.
It's not quite clear why they were added in the first place since
this should be defined in btScalar.h, needs further investigation.
Thanks to Francisco De La Cruz (xercesblue) for looking into this.
Should fix [#35071] Bullet Convex Hull Crashes on Win32 with SSE
|
|
Sent patch upstream.
Fixes [#35115] Character physics type fails collision with static type with an action on 2.67 rc
|

|
|
Apply patches in patches directory, remove patches that were applied
upstream.
If you made changes without adding a patch, please check.
Fixes [#32233] exporting bullet format results in corrupt files.

This commit is an attempt to improve collisions between moving Bullet rigid bodies using (concave) triangle mesh bounds.
Instead of using Gimpact, this we create a btCompoundShape with child shape tetrahedra derived from the surface triangles.
For each triangle, we add a fourth vertex using the centroid, shifting inwards using the triangle normal.
If the centroid hits an internal triangle, we stop. The default depth could be exposed as 'advanced' setting in the user interface.
This solution will be a slower than the original/gimpact solution, but a bit more reliable.
In the future, it is better to add HACD, convex decomposition to Blender, for moving concave meshes.
See http://kmamou.blogspot.com and the Bullet SDK's Demos/ConvexDecompositionDemo.

* Add access to the original indices for vertices
* Add a very simple C API for convex hull
* Add this patch to the patches folder and update readme.txt

by Daniel Stokes (kupoman) by applying a patch found in this Bullet bug report: https://code.google.com/p/bullet/issues/detail?id=525
|
|
Remove Jamfiles and other unused files that stuck around during previous updates.
Add patches for local changes to the patches directory.
Update readme.txt, it had outdated infromation.
|

===============================================
This patch adds a new "Character" BGE physics type which uses Bullet's btKinematicCharacter for simulation instead of full-blown dynamics. It is appropiate for (player-controlled) characters, for which the other physics types often result unexpected results (bouncing off walls, sliding etc.) and for which simple kinematics offers much more precision.
"Character" can be chosen like any other physics type in the "Physics" section of the properties window. Current settings for tweaking are "Step Height" (to make the object automatically climb small steps if it collides with them), "Fall Speed" (the maximum speed that the object can have when falling) and "Jump Speed", which is currently not used.
See http://projects.blender.org/tracker/?func=detail&atid=127&aid=28476&group_id=9
for sample blends and a discussion on the patch: how to use it and what influences the behavior of the character object.
Known problem: there is a crash if the "compound" option is set in the physics panel of the Character object.

- Remove strict flags from files, which are using FFmpeg stuff
We're still using some symbols which are marked as deprecated.
Ideally, we shall switch to new API, but it's a bit larger challenge
because we don't want to break compatibility withotu actual need.
- Replace MAKE_ID with BT_MAKE_ID in bullet library.
This is needed to prevent re-definition of MAKE_ID in bullet library.
Seems it's only used to read blender files, so should be quite safe
change.

and looks like -fpermissive is used in linux too
|
|
to ints. All cases found were harmless and the error behaviour could be turned off by the -fpermissive flag but I'd rather keep that off to detect any real problems should they arise.
|

slight modifications.
Thanks!

extern/bullet2, it will propagate to the Bullet soon from here:

Thanks to Campbell for letting me know

fix in Bullet. I will also report the fix to Erwin so that it can be added to next Bullet version.

Change OURPLATFORM from "linux<major_version>" to simple "linux".
Since new policy for linux kernel versions that major version in
platform doesn't make much sense for building rules so the same
rules could be used for both of linux2 and linux3 now/
Tested on both of linux2 and linux3 systems.

list.

blender_add_lib now takes a separate include argument to suppress warnings in system includes (mostly ffmpeg & python).
also only build wm_apple.c on apple+carbon configuration.
