GLUCYLINDER(3G) | GLUCYLINDER(3G) |
Note that if top is set to 0.0, this routine generates a cone.
If the orientation is set to GLU_OUTSIDE (with gluQuadricOrientation), then any generated normals point away from the z axis. Otherwise, they point toward the z axis.
If texturing is turned on (with gluQuadricTexture), then texture coordinates are generated so that t ranges linearly from 0.0 at z = 0 to 1.0 at z = height, and s ranges from 0.0 at the + y axis, to 0.25 at the +x axis, to 0.5 at the - y axis, to 0.75 at the -x axis, and back to 1.0 at the + y axis.
