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. To run a PS … See more WebDec 18, 2012 · Marching cubes is one of the most widely used real-time volume rendering methods. This paper describes a methodology for speeding up the marching cubes algorithm on a graphics processing unit and discusses a number of ways to improve its performance by means of auxiliary spatial data structures.
