glMultMatrixd,
glMultMatrixf
[New
- Windows 95, OEM Service Release 2]
The glMultMatrixd
and glMultMatrixf functions multiply the current matrix by an arbitrary
matrix.
void glMultMatrixd(
|
const GLdouble *m |
|
|
); |
|
void glMultMatrixf(
|
const GLfloat *m |
|
|
); |
|
Parameters
m
A pointer to
a 4x4 matrix stored in column-major order as 16 consecutive values.
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- or double-precision floating-point
values stored in column-major order. That is, the matrix is stored as:
{bml bm46.BMP}
