WebJan 22, 2016 · MORTAL, Yeah, I was thinking of adding sky and floor similarly. Though I'd also like maybe adding floor and ceiling textures as in the second tutorial.However, the way he does it there is very CPU-focused and would require me to render differently then the line-based rendering I'm doing now. WebRaycasting 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 resolutions and complex scenes.
