ed338da8c9 - WITH_CXX_GUARDEDALLOC working again
- CMake building without python or fluidsim working again (broke in recent commit)
- remove BLI_short_filename(), it wasnt used anywhere.

14d33b3c1f BGE guardedalloc, Uses WITH_CXX_GUARDEDALLOC but gives a string to MEM_mallocN for better tracking memory usage.
* off by default.
* new/delete are at the bottom of each class
* python BGE objects have the new/delete in the Py_Header macro.

c8b4cf9206 2.50:
svn merge https://svn.blender.org/svnroot/bf-blender/trunk/blender -r19820:HEAD

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* Game and sequencer RNA, and sequencer header are now out of date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.

51b4145841 BGE Scenegraph and View frustrum culling improvement.
This commit contains a number of performance improvements for the
BGE in the Scenegraph (parent relation between objects in the
scene) and view frustrum culling.

The scenegraph improvement consists in avoiding position update
if the object has not moved since last update and the removal
of redundant updates and synchronization with the physics engine.

The view frustrum culling improvement consists in using the DBVT
broadphase facility of Bullet to build a tree of graphical objects
in the scene. The elements of the tree are Aabb boxes (Aligned 
Axis Bounding Boxes) enclosing the objects. This provides good
precision in closed and opened scenes. This new culling system
is enabled by default but just in case, it can be disabled with
a button in the World settings. There is no do_version in this
commit but it will be added before the 2.49 release. For now you
must manually enable the DBVT culling option in World settings
when you open an old file.

The above improvements speed up scenegraph and culling up to 5x.
However, this performance improvement is only visible when
you have hundreds or thousands of objects.

The main interest of the DBVT tree is to allow easy occlusion
culling and automatic LOD system. This will be the object of further
improvements.

5e2ee19187 BGE patch: support for partial hierarchy in dupligroup instantiation; removal of links that point to inactive objects during group instantiation.
This situation corresponds to a group containing only a portion
of a parent hierarchy (the Apricot team needed that to avoid
logic duplication). The BGE will instantiate only the
children that are in the group so that it follows the 3D view
more closely.
As a result, the logic links to the objects in the portion of the
hierarchy that was not replicated will point to inactive objects
(if the groups are stored in inactive layers as they should be). 
To keep the logic system consistent, these links are automatically
removed.
This last part of the patch is a general fix that could go in
2.47 but as this situation does not normally occurs in pre-2.47
games, it is not needed.

a6a4b78417 Fix BGE bug #7532: TrackTo Actuator does not work correctly if it has a Vertex Parent. This is only a partial fix: the user must put the parent vertex at the center of the parent object and disable the physics on the tracking object (use empty or collision free object). 2008-05-14 20:22:57 +00:00

5d0a207ecb Patch from GSR that a) fixes a whole bunch of GPL/BL license
blocks that were previously missed; and b) greatly increase my
ohloh stats!

22ef0daefd This is patch #6825 (The patch missed a couple of them but
this should get it all.

recurse was spelled resurse in a couple of places.

3dd18c5c34 Added an UpdateTransform callback from SceneGraph -> Physics.
Profiling revealed that the SceneGraph updated every physics object, whether it moved or not, even though the physics object was at the right place.  This would cause SOLID to go and update its bounding boxes, overlap tests etc.
This callback handles the special case (parented objects) where the physics scene needs to be informed of changes to the scenegraph.

Added Python attributes (mass, parent, visible, position, orientation, scaling) to the KX_GameObject module.
Make KX_GameObject use the KX_PyMath Python <-> Moto conversion.

f1c4f705a1 Removed the config.h thing from the .h's in the source dir.
So we should be all set now :)

b9a19f1ea7 Did all of the .h's in source
(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
