glLoadMatrix — replace the current matrix with the specified matrix
void glLoadMatrixd( | const GLdouble * | m) ; |
void glLoadMatrixf( | const GLfloat * | m) ; |
m
Specifies a pointer to 16 consecutive values, which are used as the
elements of a
glLoadMatrix
replaces the current matrix with the one whose elements are specified by
m
.
The current matrix is the projection matrix,
modelview matrix,
or texture matrix,
depending on the current matrix mode
(see glMatrixMode).
The current matrix, M, defines a transformation of coordinates.
For instance, assume M refers to the modelview matrix.
If
m
points to an array of
Projection and texture transformations are similarly defined.
While the elements of the matrix may be specified with single or double precision, the GL implementation may store or operate on these values in less than single precision.
GL_INVALID_OPERATION
is generated if glLoadMatrix
is executed between the execution of glBegin
and the corresponding execution of glEnd.
