glMultTransposeMatrixf

glMultTransposeMatrix: man2/glMultTransposeMatrix.xml

glMultTransposeMatrix multiplies the current matrix with the one specified using m, and replaces the current matrix with the product. The current matrix is determined by the current matrix mode (see glMatrixMode ). It is either the projection matrix, modelview matrix, or the texture matrix.

glMultTransposeMatrix is available only if the GL version is 1.3 or greater. While the elements of the matrix may be specified with single or double precision, the GL may store or operate on these values in less-than-single precision. The order of the multiplication is important. For example, if the current transformation is a rotation, and glMultTransposeMatrix is called with a translation matrix, the translation is done directly on the coordinates to be transformed, while the rotation is done on the results of that translation.
