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* Game and sequencer RNA, and sequencer header are now out of date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

0b8661ab4d BGE: Occlusion culling and other performance improvements.
Added occlusion culling capability in the BGE. 
More info: http://wiki.blender.org/index.php/Dev:Ref/Release_Notes/2.49/Game_Engine#BGE_Scenegraph_improvement
MSVC, scons, cmake, Makefile updated.

Other minor performance improvements:
- The rasterizer was computing the openGL model matrix of the objects too many times
- DBVT view frustrum culling was not properly culling behind the near plane:
  Large objects behind the camera were sent to the GPU
- Remove all references to mesh split/join feature as it is not yet functional

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.

becd467be8 BGE patch: KX_GameObject::rayCast() improvements to have X-Ray option, return true face normal and hit polygon information.
rayCast(to,from,dist,prop,face,xray,poly):

The face paremeter determines the orientation of the normal: 
  0 or omitted => hit normal is always oriented towards the ray origin (as if you casted the ray from outside)
  1 => hit normal is the real face normal (only for mesh object, otherwise face has no effect)
The ray has X-Ray capability if xray parameter is 1, otherwise the first object hit (other than self object) stops the ray.
The prop and xray parameters interact as follow:
    prop off, xray off: return closest hit or no hit if there is no object on the full extend of the ray.
    prop off, xray on : idem.
    prop on,  xray off: return closest hit if it matches prop, no hit otherwise.
    prop on,  xray on : return closest hit matching prop or no hit if there is no object matching prop on the full extend of the ray.
if poly is 0 or omitted, returns a 3-tuple with object reference, hit point and hit normal or (None,None,None) if no hit.
if poly is 1, returns a 4-tuple with in addition a KX_PolyProxy as 4th element.

The KX_PolyProxy object holds information on the polygon hit by the ray: the index of the vertex forming the poylgon, material, etc.

Attributes (read-only):
 matname: The name of polygon material, empty if no material.
 material: The material of the polygon
 texture: The texture name of the polygon.
 matid: The material index of the polygon, use this to retrieve vertex proxy from mesh proxy
 v1: vertex index of the first vertex of the polygon, use this to retrieve vertex proxy from mesh proxy
 v2: vertex index of the second vertex of the polygon, use this to retrieve vertex proxy from mesh proxy
 v3: vertex index of the third vertex of the polygon, use this to retrieve vertex proxy from mesh proxy
 v4: vertex index of the fourth vertex of the polygon, 0 if polygon has only 3 vertex
     use this to retrieve vertex proxy from mesh proxy
 visible: visible state of the polygon: 1=visible, 0=invisible
 collide: collide state of the polygon: 1=receives collision, 0=collision free.
Methods:
 getMaterialName(): Returns the polygon material name with MA prefix
 getMaterial(): Returns the polygon material
 getTextureName(): Returns the polygon texture name
 getMaterialIndex(): Returns the material bucket index of the polygon. 
 getNumVertex(): Returns the number of vertex of the polygon.
 isVisible(): Returns whether the polygon is visible or not
 isCollider(): Returns whether the polygon is receives collision or not
 getVertexIndex(vertex): Returns the mesh vertex index of a polygon vertex
 getMesh(): Returns a mesh proxy

New methods of KX_MeshProxy have been implemented to retrieve KX_PolyProxy objects:
 getNumPolygons(): Returns the number of polygon in the mesh.
 getPolygon(index): Gets the specified polygon from the mesh.

More details in PyDoc.

8a8a12ed84 BGE patch: logic optimization part 2: remove inactive sensors from logic manager.
With this patch, only sensors that are connected to 
active states are actually registered in the logic
manager. Inactive sensors won't take any CPU,
especially the Radar and Near sensors that use a
physical object for the detection: these objects
are removed from the physics engine.

To take advantage of this optimization patch, you
need to define very light idle state when the 
objects are inactive: make them transparent, suspend
the physics, keep few sensors active (e,g a message
sensor to wake up), etc.

28bbf2d616 - added support for generic 6DOF constraint
- only 6DOF constraint shows buttons for limits
- added python support for rigidbody constraint (untested, but required for COLLADA Physics support)

6f3e593105 more graphics patches from Snailrose,
remove constraint fixed,
Bullet timestep now subdivides Blender game engine timestep, so it runs 60 hertz,
SphereShape reverted to old style, so no support for non-uniform scaled spheres for now,

38b993f787 Speed up the physics engine: hook the SOLID broad phase, so we can either reject the test or request the penetration depth test as necessary. Previously we were doing the penetration depth test, as well as SOLID's intersection test. 2004-11-06 04:58:10 +00:00

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
