Abstract
A method is provided for calculating edge normals when transformingD geometric data (e.g., polygon mesh data) to voxel data, which includes four steps. First, each geometric unit (e.g., each polygon) in theD geometric data is mapped to a voxel grid. Second, edge voxels are detected in the voxel grid. As used herein, an edge voxel means a voxel forming an edge of an object to be rendered. Third, for each edge voxel, one or more normals of the one or more geometric units that intersect with that edge voxel are calculated and stored. Fourth, for each edge voxel, an edge normal is obtained by combining (e.g., equal-weight-averaging) the one or more normals stored in association with that edge voxel.
