Now a boundary and corner patch remains aligned with its underlying parametric orientation. This simplifies both the gathering of patch vertices and downstream evaluation of patches. Added a method to Vtr::Level which gathers the 16 patch points for a B-spline patch even if the patch has boundary or corner edges. The undefined patch vertex index values along boundary and corner edges are assigned Vtr::INDEX_INVALID. In order to simplifiy the process of drawing B-spline patches with boundary or corner edges, the Far::PatchTablesFactory will replace any invalid vertex indices with a known good value, i.e. the index of the first patch face vertex. Single-crease patches are still a slightly special case, which will be resolved later. |
