I'm using gb.sdl and gb.opengl. I load an image into RAM like this:
Public tTest As Image
tTest = Image.Load("test.png")
and want to upload it to video memory with this:
How do I obtain an ID (id) from the image loaded in RAM? From what I've
read, you need to load the image as an SDL surface, then use a property
of that surface to obtain the "handle" which is then passed to OpenGL
via BindTexture. I don't think the current SDL implementation supports
creating surfaces, and other than a pointer (tTest.Data) there appears
to be no property that returns the number required byBindTexture.
So far the OpenGl tutorials I've been reading are pretty
straightforward, but I can't get past this. tommyline, if you're out
there please hook me up with your example apps which are dead on
