3D Transformations

All OpenGL transformation functions are 3D; we can now use the Z coordinate

glTranslatef(x, y, z)

Moves objects by (x, y, z) units.

glRotatef(angle, x, y, z)

Rotates objects around the axis (x, y, z), by angle degrees.

Note that "the axis (x, y, z)" means a line that from the origin (0, 0, 0) through the point (x, y, z)

glScalef(x, y, z)

Resizes objects by the factor x in the X direction, y in the Y direction, and z in the Z direction.
