WebJun 15, 2004 · In this paper we apply a run--based ray--traversal algorithm to accelerate the ray tracing of height fields. To intersect the ray and the height field three processes occur: the ray is traversed through the grid that underlies the height field, an intersection between each cell and the ray is sought and if found the intersection point between the ray and the … WebNov 13, 2014 · The first step in our ray trace procedure is to compute a gridded refractivity field that can be used for the ray tracing. For the work reported in this paper, we used the GSFC GMAO GEOS 5.9.1 model. This model is a terrain-following model from which we have extracted surface pressure, pressure level thickness, geopotential heights, temperature, … WebA run-based line digitizing algorithm is applied to accelerate the ray traversal process when ray tracing height fields.

WebM.: Ray Tracing Height Fields by Huamin Qu, Feng Qiu, Nan Zhang, Arie Kaufman, Ming Wan - In: Procedings of Computer Graphics International , 2003 We present a novel surface reconstruction algorithm which can directly reconstruct surfaces with different levels of smoothness in one framework from height fields using 3D discrete grid ray tracing. 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.
