Ray marching vs voxel

Webas commonly done with the marching cube algo-rithm [LC87] for rendering on rasterization devices. With ray tracing the necessary ray-surface intersec-tions are computed on the fly at all relevant voxels, which allows for instantly changing the iso-value without the need for a costly re-computation of an iso-surface representation. WebAnswer (1 of 2): It's probably more useful to compare ray *casting* and ray marching. Ray tracing is more typically used to refer to the algorithm that generates the canonical rendered images using ray casting. The core component for a rendering algorithm is to evaluate how much light is coming...
