    Re: ray casting

    OpenGL is raster, however you can either write a raytracer which outputs to a texture to display in OpenGL, or you can do it using Shaders http://www.daimi.au.dk/~trier/?page_id=98 or more specifically http://www.daimi.au.dk/~trier/raycasting_shader.cg for an example

    Regards
