Glmultmatrix - HP b2600 Reference Manual

glMultMatrix

glMultMatrixd, glMultMatrixf: multiply the current matrix with the specified
matrix.
C Specification
void glMultMatrixd(
void glMultMatrixf(
Parameters
m
Description
glMultMatrix 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.
Examples
If the current matrix is C, and the coordinates to be transformed are, v = (v[0], v[1], v[2],
v[3]. Then the current transformation is C
Calling glMultMatrix with an argument of m = m[0], m[1], . . ., m[15] replaces the
current transformation with (C

Notes
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.
