Constructor & Destructor Documentation
Member Function Documentation
Builds a matrix that maps the given local space forward direction vector to point towards the given target direction, and the given local up direction towards the given target world up direction.
Generates a lookat matrix.
|modelForward ||The forward direction in the local space of the object. |
|targetDirection ||The desired world space direction the object should look at. |
|modelUp ||The up direction in the local space of the object. This vector must be perpendicular to the vector localForward. |
|worldUp ||The global up direction of the scene in world space. The worldUp and targetDirection vectors cannot be collinear, but they do not need to be perpendicular either. All the parameters MUST be normalized.|

Inverts a matrix in place.
This function avoid having to do generic Gaussian elimination on the matrix by assuming that the top-left 3x3 part of the matrix is orthonormal (columns and rows 0, 1 and 2 orthogonal and unit length). See e.g. Eric Lengyel's Mathematics for 3D Game Programming and Computer Graphics, p. 82.
