The glScaled and glScalef functions multiply the current matrix by a general scaling matrix.
void WINAPI glScaled( GLdouble x, GLdouble y, GLdouble z );
Scale factors along the x axis.
Scale factors along the y axis.
Scale factors along the z axis.
This function does not return a value.
The following error code can be retrieved by the glGetError function.
||The function was called between a call to glBegin and the corresponding call to glEnd.
The glScaled function produces a general scaling along the x, y, and z axes. The three arguments indicate the desired scale factors along each of the three axes. The resulting matrix is
The current matrix (see glMatrixMode) is multiplied by this scale matrix, with the product replacing the current matrix. That is, if M is the current matrix and S is the scale matrix, then M is replaced with M S.
If scale factors other than 1.0 are applied to the modelview matrix and lighting is enabled, automatic normalization of normals should probably also be enabled (glEnable and glDisable with argument GL_NORMALIZE).
The following functions retrieve information related to glScaled:

glGet with argument GL_MODELVIEW_MATRIX
glGet with argument GL_PROJECTION_MATRIX
glGet with argument GL_TEXTURE_MATRIX
