Hi Danny, PMJI, but I was curious about your metaballs routine if you can comment: 1) Have you considered providing some type of quick preview of the blobbed surface within the routine ? 2) As above, but *AS* the composite surface is *being* created ? (perhaps by showing a 2D cross-section of the isosurface formed by the interaction of one or more spheres from a selected viewport ? (rubber-band line style to help in placing spheres) 3) Will assigned surface color/attributes for a given sphere be blended with it's neighbor sphere(s) as well ? 4) I'm assuming since triangles will have to be created/dumped into the renderer, one can texture map this type of metaball. Is this correct ? 5) Have you considered using other geometric primitives along with spheres ? (I've only seen one other program do this) Sorry for buggin' you, and if you can't answer any/all questions, I understand….but please keep the above in mind. BTW, does your Bezier Patch modeling IPAS create *RATIONAL* patches ? Regards, BILL
