How to load a Texture in Ruby-Opengl

[onionblossom]

Hi,

I don't get it working in Ruby. I try to load a texture which works
pretty easy in other languages like c++ and there are plenty of
examples in other languages but none for Ruby.

The file could be any format but I like to keep it simple: ppm or raw.
Can anyone give me a hint or a snippet how to do it?

thanx ahead

It works the same way as in C or other languages, you need library (like
RMagick/ImageMagick,SDL_image etc.) that decodes the image format to raw
pixel data in memory (in ruby it's represented as string), then pass it to
the opengl functions (glTexImage*).

Thanx, I solved the problem by using the sdl library
