glMultMatrixf function

The glMultMatrixd and glMultMatrixf functions multiply the current matrix by an arbitrary matrix.

Syntax

void WINAPI glMultMatrixf(
   const GLfloat *m
);

Parameters

m

A pointer to a 4x4 matrix stored in column-major order as 16 consecutive values.

Return value

This function does not return a value.

Error codes

The following error code can be retrieved by the glGetError function.

Remarks

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-precision or double-precision floating-point values stored in column-major order. That is, the matrix is stored as shown in the following image.
