Ray tracing height fields Abstract: 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 rectangular grid from ...

There have been lots of papers over the years on different techniques for drawing height-field terrain in a ray-tracer. Some algorithms ray-march the grid directly (or via a quadtree); others transform the terrain into a polygon mesh and use a standard ray-triangle intersection test.

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 height field is calculated.
Height Fields in Povray (Ray Tracing Elevation Data, Part II)
https://shallowsky.com/blog/mapping/height-fields-in-povray.html
Height Fields in Povray (Ray Tracing Elevation Data, Part II) This is Part II of a four-part article on ray tracing digital elevation model (DEM) data. (Actually, it's looking like there may be five or more parts in the end.) The goal: render a ray-traced image of mountains from a digital elevation model (DEM).
