struct varjo_Matrix |
Double precision 4x4 matrix.
The matrix usage convention is that they are stored in column-major order and transforms are stacked before column-vector points when multiplying. That is, a pure translation matrix will have the position offset in elements 12..14.
Unless otherwise specified, the coordinate system is right-handed: X goes right, Y goes up and negative Z goes forward.
