Concatenates the input matrix with the current transformation matrix. The resulting matrix becomes the new current transformation matrix. The setting of the PreMultiply flag determines whether the matrix is PreConcatenated or PostConcatenated. Transposes the current transformation matrix. Returns the current transformation matrix.
Point is expressed in homogeneous coordinates.
The setting of the PreMultiplyFlag will determine if the Point is Pre or Post multiplied. This is a special multiplication, since these are vectors. It multiplies vectors by the transposed inverse of the matrix, ignoring the translational components. This is a special multiplication, since these are normals. It multiplies the normals by the transposed inverse of the matrix, ignoring the translational components.
