Re: [pygame] pygame - writing over existing window information

["Ian Mallett" <geometrian@xxxxxxxxx>]

To copy the screen contents to a texture, do something like:

screentexture = glGenTextures(1)

def copy_screen_to_texture():

    glBindTexture(GL_TEXTURE_2D,screentexture)

    glCopyTexImage2D(GL_TEXTURE_2D,0,GL_RGB,0,0,screenwidth,screenheight,0)

    glTexParameterf(GL_TEXTURE_2D,GL_TEXTURE_MIN_FILTER,GL_NEAREST)

    glTexParameterf(GL_TEXTURE_2D,GL_TEXTURE_MAX_FILTER,GL_NEAREST)

Completely untested, but should work without too much trouble.

Cheers,

Ian
