Conceptually, generating a block of terrain involves two main steps. We outline the steps here and then elaborate upon them in the following subsections. 1. First, we use the GPU's pixel shader (PS) unit to evaluate the complex density function at every cell corner within the block and store the results in a large 3D … See more The generation of polygons within a cell works as follows: As shown in Figure 1-3, we take the density values at the eight corners and determine whether each value is positive or … See more Two primary lookup tables are at work here. The first, when indexed by the case number, tells us how many polygons to create for that case: The second lookup table is much larger. … See more The sole input to the density function is this: This value is the world-space coordinate. Luckily, shaders give us plenty of useful tools to translate this value into an interesting density value. Some of the tools at our disposal … See more Rendering to a 3D texture is a somewhat new idea, and it's worthy of some explanation here. On the GPU, a 3D texture is implemented as an array of 2D textures.

Reusing vertices while using marching cubes/tetrahedra

WebReusing the vertices can save you memory and save time spent sending data to the GPU. It's really only worth the trouble if you have a large number of voxels. I've done this with marching cubes, but I'm not sure the same approach would work for tetrahedra. For marching cubes, the vertices lie along the edges. Each edge is shared by up to 4 cubes.
