1) glCopyTexImage2D - www.opengl.org/sdk/docs/man/xhtml/glCopyTexImage2D.xml
2) dome post_draw. Now dome mode can also use scene.post_draw. It only runs for the last scene. It's really useful. I'm working on a nice showcase for this (a dome visualizer for the dome mode running with bgl. In the mean time this is a (lame) example of both working together (the buffer is being copied and draw on top of the window):

unrelated changes that ended up being more trouble to commit separate...
- removed BLI_split_dirfile(), was nasty, occasionaly modifying the source string, it could create directories and used the $CWD in some cases. was only used in 2 places in filesel.c, if this gives problems can address without bringing back this function.
renamed BLI_split_dirfile_basic --> BLI_split_dirfile
- view3d_operator_needs_opengl was being called for offscreen render when it wasnt needed.
Originally we had 2DFilters (m_filtermanager) stored in RenderTools. That way filters were stored globally and were being called once per each scene. This was producing two big problems: (1) performance and (2) flexibility of use.
(1) Performance - To run the filters 2X == 2X slower
(2) flexibility of use - Very often we want the filter in the scene but not in the UI for example.
For those reasons I believe that 2DFilters with multiple scenes was very useless or unpredictable. I hope they work fine now.
To make it work as before (2.4) you can simply recreate the 2dfilter actuators across the scenes.
* * * * *
Imagine that we have:
(a) Main Scene
(b) Overlay Scene
in Main Scene the Z Buffer and RGB will be from the main scene.
in Overlay Scene the Z Buffer will be from the Overlay Scene and the RBG buffer is from both [(a + 2D Filter) + b].
So in pseudo code if we have a,b,c,d,e scenes we have: (2DFilterE(2DFilterD(2DFilterC(2DFilterB(2DFilterA(a) + b) + c) + d) + e)
... what lead me to wonder if we should remove obj.setAngularVelocity, obj.setLinearVelocity, obj.getLinearVelocity and obj.getAngularVelocity.
* this was so Copy and Paste ... anyways tests are welcome (I never used those methods in python myself).
- recode of the whole sequencer audio handling
- encode audio flag removed, instead you choose None as audio codec, added None for video codec too
- ffmpeg formats/codecs: enabled: theora, ogg, vorbis; added: matroska, flac (not working, who can fix?), mp3, wav
- sequencer wave drawing
- volume animation (now also working when mixing down to a file!)
- made sequencer strip position and length values unanimatable
act.time can set the sound position (float in seconds)
act.is3D RO gives you the dimension of the audio
act.minGain3D, maxGain3D ... set the 3D parameters of the sound
** PyDoc to be done. Jörg Müller (NeXyon) do you want to document them? The file is here:
//source/gameengine/PyDoc/GameTypes.py
+ adding a missing \n to KX_Scene.cpp. (kind of typo)
A btBvhTriangleMeshShape object is created when converting
a mesh to physics, also in case of Soft body although the
soft body will not use it (it only uses the mesh interface).
This patch keeps this system for compatibility with the
KX converter but avoids the creation of the BVH structure,
which consumes a lots of CPU. This should speed up
significantly the conversion of large mesh to softbody.
A secondary optimization is that the sharing of shapeInfo
is extended to rigid body using gImpact. Before it was
only active between static body and soft body.
Assignment to KX_GameObject localOrientation and
worldOrientation matrices was assuming row-major matrix
although reading these matrices was returning a column-major
MathUtils object.
The faulty function (PyMatTo) is fixed and all matrices
in python are now assumed column-major.
This function is also used in the following methods:
BL_Shader.setUniformMatrix4()
BL_Shader.setUniformMatrix3()
(No change in scripts if you didn't specify the optional
transpose parameter: the default value is changed so
that column-major matrices are assumed as before.)
KX_Camera.projection_matrix
(assignement to this attribute now requires a column-major
matrix and you must fix your script if you were setting
a value to this attribute.)
Even a static mesh can be used as replacement: the mesh
will be instantiated with the soft body settings of the
object. The position and orientation of the soft body
is preserved after the replacement.
Known limitation: the velocity of the soft body is reset
aftet the replacement. This is because soft body don't
have a well defined velocity.
patch from Mitchell Stokes (moguri)
simple use case
scene.post_draw = [pyOpenGLFunc]
this only needs to be set once, then the funcion runs each redraw.
note, this patch also changes how python scripts run (not modules): Dont clear the namespace after running a script, since functions still use the namespace, BGE API is now better when dealing with stale data.
made some changes to this patch.
- assigning a list didnt decrement the existing list.
- initialize as NULL rather then a blank list
- dont use string comparisons for the callbacks, pass the python list to use instead.
- dont check the list items are callable. python will display an error if they are not.
- use python list macros that dont do any type checking sine blender does this when assigning the list
---- from tracker, edited since an updated patch changes some things.
Here is a patch to be able to draw to the screen with BGE Python. This will be very handy for GUI stuff. This patch
works by having the user register a callback in the scene. Two options are available KX_Scene.pre_draw
and KX_Scene.post_draw. The difference between these is when Python draws to the screen (before or after the BGE).
Each can take a list of functions. Here is an example that draws a blue semi-transparent
GLEW update to version 1.5.1 [11-03-08]
this opens room for Geometry Shader support.
* - Brecht, Campbell told me you did some local changes in order to make it right in Linux. I get to you in order to know what those changes are (or feel free to commit them directly)
* Convert all code to use new functions.
* Branch maintainers may want to skip this commit, and run this
conversion script instead, if they use a lot of math functions
