Wow! Talk about a no brainer! If that's what a raycaster is, than I need source code for my microwave oven! Or my laser pen! Or my monitor! Or perhaps the sun! Because all of them cast rays, and according to parksie's literalistic nonsense, they would all be raycasters! DUH!!!!


OK-- ray tracer: follows rays of light along their paths and waits for them either to die or hit the viewing plane. If an intersection with the view plane is detected, the corresponding pixel is set with the appropriate color based on what mediums etc the ray has dealt with in its short life.

Now -- ray caster: a foward looking ray tracer that works based on geometric constraints; for each pixel in the view region, a ray caster follows an imaginary "ray" along its path until the ray hits something or reaches some boundary, e.g. a clip plane or a world edge. When the ray ceases to travel, the engine calculates what the ray has hit or why it stopped and assigns its corresponding pixel a color.

So you ask why do I want code if I already know all this? Because I want code!! Don't ask stupid questions.

So now that we all are completely confused, why don't we just give up because none of you should be posting answers in this thread as none of you have a clue what you're talking about.
