glMultMatrix
Chapter 11
290
In many computer languages, 4 × 4 arrays are represented in row-major order. The
transformations just described represent these matrices in column-major order. The
order of the multiplication is important. For example, if the current transformation is a
rotation, and glMultMatrix is called with a translation matrix, the translation is done
directly on the coordinates to be transformed, while the rotation is done on the results of
that translation.
Errors
• GL_INVALID_OPERATION is generated if glMultMatrix is executed between the
execution of glBegin and the corresponding execution of glEnd.
