WebSep 1, 1999 · It has been shown that height field ray tracing efficiency can be improved by traversing rays in steps across evenly spaced inverted cones of empty space centered … WebOnce we have transformed the viewing ray into tangent space, the algorithm proceeds exactly as in the planar case. Now that we know how to use a distance map for ray tracing, we need to know how to efficiently compute a distance map for an arbitrary height field. 8.4 Computing the Distance Map.

WebAug 10, 2024 · The ray-tracing method developed in our group is employed for calculating received fields. The 30,000 transmitting points are divided into 2 groups: one with 25,000 points for training purposes and the one with the remaining 5,000 signals for determining the prediction accuracy. 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.
