ray casting

[muster]

Hello all,

can someone explain how can i make a ray casting rendering in opengl?

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
