As part of the early phase of experimentation in a potential project, I started fiddling with creating custom geometry in pv3d, rather than tweaking the vertices of existing primitives. The results so far aren’t perfect, but they’re looking good:
I’m not sure whether this is re-creating functionality that other people have already put into papervision, but it was a lot of fun! There are some issues with shaded materials, but so far I have bitmap- and colour materials displaying and it’s looking good. You can try it for yourself! Like the pale text says – click in the window to add a vertex, press space to close the shape. It seems to work even on pretty low-powered machines, so give it a try!
