The glMultMatrixd and glMultMatrixf functions multiply the current matrix by an arbitrary matrix.
void glMultMatrixd( const GLdouble *m ); void glMultMatrixf( const GLfloat *m );
- A pointer to a 4x4 matrix stored in column-major order as 16 consecutive values.
The glMultMatrix function multiplies the current matrix by the one specified in m. That is, if M is the current matrix and T is the matrix passed to glMultMatrix, then M is replaced with M • T.
The current matrix is the projection matrix, modelview matrix, or texture matrix, determined by the current matrix mode (see glMatrixMode).
The m parameter points to a 4x4 matrix of single- or double-precision floating-point values stored in column-major order. That is, the matrix is stored as:
The following functions retrieve information related to glMultMatrix:
glGet with argument GL_MATRIX_MODE
glGet with argument GL_MODELVIEW_MATRIX
glGet with argument GL_PROJECTION_MATRIX
glGet with argument GL_TEXTURE_MATRIX
