Fixed bug in generic attribute support
Written by

Snaking.
Working up the sample code for the "legacy free" section of the PyOpenGL talk for PyCon I discovered that the glVertexAttribPointer wrapper never got finished. You could pass in c_void_pointers, but other than that it just wouldn't work. Obviously not a lot of people using the generic attribute support in PyOpenGL... but then I knew ...

To try to help out with Seneca's presentation today on the Python interface to CSound I tried to create a small demonstration application. It shows the use of CSound's "real time" Python API, that is, the API that allows you to poke notes directly into the score buffer for playing.

glInterleavedArrays is deprecated...
Written by

Snaking.
Doing a bit of after-work hacking on the PyOpenGL presentation, just realized that glInterleavedArrays is deprecated. It's pretty trivial to rewrite as array pointers when you have VBO objects:
glInterleavedArrays( GL_T2F_N3F_V3F, 0, data )
Becomes:
glEnable( GL_VERTEX_ARRAY )
glEnable( GL_NORMAL_ARRAY )
glEnable( GL_TEXTURE_COORD_ARRAY )
glVertexPointer( len(data), GL_FLOAT, 32, data+20 )
glNormalPointer( len(data), GL_FLOAT, 32, data+8 ...
Presentations are Roughed Out
Written by

Snaking.
Have the basic outline for the two PyCon presentations worked out now. I'll need some more work to pull together really good sample code for the PyOpenGL one. I added the ability to load multiple profile files to RunSnakeRun as I worked on the profiling presentation (one of those, "oh, yeah, I'm describing how to ...
