glLoadMatrixd function
The glLoadMatrixd and glLoadMatrixf functions replace the current matrix with an arbitrary matrix.
Syntax
void WINAPI glLoadMatrixd(
const GLdouble *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.
| Name | Meaning |
|---|---|
|
The function was called between a call to glBegin and the corresponding call to glEnd. |
Remarks
The glLoadMatrix function replaces the current matrix with the one specified in m. 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.
