Methods and apparatus for representing a field over a triangular mesh are disclosed. A two-dimensional (2D) triangular map may be created for each triangle of a three-dimensional (3D) triangular mesh. The triangular map may be recursively subdivided to create a plurality of sub-triangles. The sub-triangles may be sampled, and an field may be measured or calculated at each level of the recursion. The map of field values may use various compression techniques and may also employ a delayed reading technique. The map may be multi-resolution, hierarchical, and partitioned. |
