glScale, glScaled, glScalef - multiply the current matrix by a general
GLdouble z ); void glScalef(
GLfloat z );
Specify scale factors along the x, y, and z axes, respectively.
DESCRIPTIONglScale() produces a nonuniform scaling along the x, y, and z axes. The
three parameters indicate the desired scale factor along each of the
The current matrix (see glMatrixMode()) is multiplied by this scale
matrix, and the product replaces the current matrix as if glScale()
were called with the following matrix as its argument: x 0 0 0 0 y 0 0
0 0 z 0 0 0 0 1
If the matrix mode is either GL_MODELVIEW or GL_PROJECTION, all objects
drawn after glScale() is called are scaled.
Use glPushMatrix() and glPopMatrix() to save and restore the unscaled
If scale factors other than 1 are applied to the modelview matrix and
lighting is enabled, lighting often appears wrong. In that case, enable
automatic normalization of normals by calling glEnable() with the argu‐
GL_INVALID_OPERATION is generated if glScale() is executed between the
execution of glBegin() and the corresponding execution of glEnd().
