Richard, I'm not getting it. I am running the "shapes" demo with a cube, a tetrahedron, and a torus (all solid) and enabling "GL_CULL_FACE" and not seeing anything improper. What am I missing?

Subject: [Freeglut-developer] og_geometry.c John Fay has been going through OpenGLUT to get some of the OpenGLUT bug fixes copied into freeglut. He didn't mention which bugs he saw fixed in OpenGLUT that he would be fixing in freeglut, but his post reminded me of a fairly big one I saw early on with OpenGLUT and fixed months ago. In freeglut, several of the geometry objects are drawn with reversed winding on the solid-shaded objects. All of these were identified and fixed in OpenGLUT in March, give or take a month I think. freeglut at last word still draws several solid-shaded objects incorrectly. In fact, I think that about the only solid-shaded objects that freeglut gets correctly are the ones that Nigel fixed (and the cylinder that he added?) in Fall of 2003. This is readily apparent if you have the objects animated with back faces culled. Just a FYI. -- "I probably don't know what I'm talking about." http://www.olib.org/~rkr/ |

Nigel, I believe you did get those fixes into "freeglut" ahead of the fork. I'm not finding serious problems with the geometry functions. John F.

Richard, I've been using the "freeglut" "shapes" demo with slight modifications to look at other shapes. If the "freeglut" powers that be say it's okay, may we import the OpenGLUT "shapes" demo and use it as a "freeglut" demo? John F.

Subject: [Freeglut-developer] og_geometry.c John, The freeglut "shapes" demo only included the shapes that Nigel reworked last year, as I recall. Are you using the OpenGLUT shapes demo, or the freeglut one? (The two are vastly different.) As for the geometry: Well, try some of the others. I recall the octahedron in particular was a 50-50 mix of CW and CCW windings. Maybe the cube and tetrahedron were right. Nigel fixed the torus a year ago in freeglut. -- "I probably don't know what I'm talking about." http://www.olib.org/~rkr/ |

Richard, The OpenGLUT "shapes" demo is indeed a very good thing. I looked at the shapes and apparently the only one still with problems is the octahedron. I'll be taking a look at it later. John F.
