Marching cubes and dual contouring are often used for mesh generation. The Marching cubes algorithm can be described as follows: Given an object, a test to determine whether an arbitrary point is within the object, and bounds within which the object exists: Divide the space within the bounds into an arbitrary number of cubes. Other algorithms require a so-called isovalue , for which a value of 0. A volume may contain discrete integer values, often the result of segmentation. Unreal Engine 4 —— Marching Cube算法的.
