This method loads a matrix.
- Parameters
-
MatrixMode | The matrix mode for which the matrix should be loaded (MODELVIEW, PROJECTION, TEXTURE, MATRIX0, ...). |
Matrix | The matrix that is to be loaded. The matrix must be up-to-date already, i.e. Matrix.Update() must have been called by the caller! Note that individual matrices are discriminated by their ID(!), not by their actual content value. Also, the age of a matrix should increase whenever the matrix is modified. |
