glutWireOctahedron -- Draw a wireframe octahedron.
OpenGLUT - geometry
This function draws a regular wireframe 8-sided polyhedron centered at the origin. The vertices are at (+/-1, 0, 0), (0, +/-1, 0), (0, 0,
We visit the same vertices the same number of times as for the solid octahedron, but the order is different.
Draws every edge twice.
The lines have normals, but the normals are from the facets, rather than upon the edge. If you squint too hard, the lighting on a wireframe
octahedron does not look quite right.
It may be faster (and look better) to draw each edge once, setting the Normal at each edge. (I don't think that this matters all that much,
but a lineloop was proposed for the wire Cube for speed.)

glutSolidTeapot, glutWireTeapot - render a solid or wireframe teapot respectively.
void glutSolidTeapot(GLdouble size);
void glutWireTeapot(GLdouble size);
size Relative size of the teapot.
glutSolidTeapot and glutWireTeapot render a solid or wireframe teapot respectively. Both surface normals and texture coordinates for the
teapot are generated. The teapot is generated with OpenGL evaluators.
The teapot is greatly over-tesselated; it renders way too slow.
OpenGL's default glFrontFace state assumes that front facing polygons (for the purpose of face culling) have vertices that wind counter
clockwise when projected into window space. This teapot is rendered with its front facing polygon vertices winding clockwise. For
OpenGL's default back face culling to work, you should use:
Both these bugs reflect issues in the original aux toolkit's teapot rendering routines (GLUT used the same teapot rendering routine).
