Unigine::Math::dmat4 Struct

The dmat4 matrix is used for world transformations only (translation, scaling, rotation). This matrix isn't used for 3D projection, so its last row is skipped (that's why its size is 3x4 not 4x4). It allows avoiding high memory usage and performance loss when using the double precision coordinates.

The first, the second and the third columns of the matrix represent the rotation and the scale of the origin. The last column contains the translation of the origin relatively to the world origin.

For any other purposes, the mat4 matrix can be used.
