[PyOpenGL-Users] glTexSubImage2D data format

[Mohan G. <mg...@ca...>]

Hi,

I'm trying to port some very elementary GPGPU code (based on 
http://www.mathematik.uni-dortmund.de/~goeddeke/gpgpu/tutorial.html) to run 
with Python(+PyOpenGL+pygame). I'm running into some difficulties 
translating the following line...

glTexSubImage2D(GL_TEXTURE_RECTANGLE_ARB, 0, 0, 0, width, height, 
GL_LUMINANCE, GL_FLOAT, data)

I think the problem is that I don't have 'data' in the right format. (I've 
tried several things, including arrays and strings. In the original C code 
it's just a float*.) Would anyone be able to tell me what the appropriate 
format in Python would be?

Thank you in advance,
Mohan
