Ray tracing height fields
WebMar 31, 2024 · Under the Paraxial Ray Trace Data, the Y-height at the stop (surface #12) is reported as being 0.424804 and - under the Real Ray Trace Data - 0.432259. This difference between the real and paraxial marginal ray height is much larger for field #2 as evident from the ray trace calculation and the 2D layout above.

WebAn alternative to classic ray-tracing is ray-marching, in which we take a series of finite steps along the ray until we strike an object or exceed the number of permitted steps. Also sometimes called ray casting Scene objects only need to answer, “has this ray hit you? y/n” Great solution for data like height fields Unfortunately…
