TīmeklisCasting rays You can see the problem here : when we use a fixed angle, the only thing guaranteed to be constant are those arcs of circle between two rays. But what should be constant are the segments on the projection plane. We can see by using a fixed angle, that the segments get longer the farther from the center. TīmeklisRay casting is not the same as ray tracing! Raycasting is a fast semi-3D technique that works in realtime even on 4MHz graphical calculators, while raytracing is a realistic rendering technique that supports reflections and shadows in true 3D scenes, and only recently computers became fast enough to do it in realtime for reasonably high ...
