Parameters
| Name | Description |
|---|---|
| Mesh | Surface mesh to consider |
| TriangleIndex | The triangle whose interior angle is considered |
| VertexIndex | The vertex whose interior angle gradient is computed (note this a global mesh vertex index, not [0,1,2]) |
| WRTVertexIndex | The gradient is computed with respect to this vertex's position |
