Ray tracing height fields
WebCiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): 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. Our algorithm exploits the 2.5D nature of the elevation data and the regularity of the rect … 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…

Cameras have depth-of-field because they are not really a pinhole model. Instead, they have an aperture that allows light in within a certain diameter. This is equivalent to taking a pinhole camera and taking a lot of pictures within that ...

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 … WebJul 11, 2003 · We present a novel surface reconstruction algorithm which can directly reconstruct surfaces with different levels of smoothness in one framework from height …
