| Class | |
| Foam::BarycentricTensor | |
| Description | |
| Templated 4x3 tensor derived from VectorSpace. Has 12 components. Can | |
| represent a barycentric transformation as a matrix-barycentric inner- | |
| product. Can alternatively represent an inverse barycentric transformation | |
| as a vector-matrix inner-product. | |
