The good news is that our volume is static. The voxels are generated when we create our 3D texture (section Generating a Volume). It’s thus possible to pre-compute all the gradients and save them into another 3D texture. ipswich v barrow

WebJul 1, 2016 · Raymarching with Constant Step. The first implementation of raymarching introduced in Volume Rendering used a constant step. Each ray is extended by STEP_SIZE in the view direction, until it hits something. If that’s the case, we draw red pixel, otherwise a white one. Raymarching with constant step can be implemented with the following code:
