Why, thanks for asking... I've used Mesh_Obj a number of times, so I've trod this path before. Last time I used it was to make a little animated GIF of a 3-D rendering of my business logo for my home page (www.d-jackson.com). In case anyone's curious, I just added a link to the source code for djsclogo.pro, here using types 4, 5 and 6 to make spheres, cylinders and tori. Fun stuff! (I used the XObjView routines to arrange the snapshots for the animation frames, but that part could equally be done using Coyote or Function graphics)

Cheers,d
