Tris vs Quads
« on: May 04, 2008, 11:05:36 AM »
I would like to see the ability to output to quads because this is a lot more useful in real terms

I can see Shapeshop being a really useful tool if it exported to quads

Now i know tris are probably used because you cant have a non planar tri

Actually, tris are used because automatically quad-meshing an implicit surface is extremely difficult. Basically, there are no algorithms to go directly from the internal representation in ShapeShop to a quad mesh. So, the best that I could do is try to convert the triangle mesh to a quad mesh. This is a highly active area of research in computer graphics, because it is so difficult. Even implementing the known algorithms are really tricky to implement, and still have no real guarantees about producing a sensible quad mesh.

I will add it to the list, and keep a look out for code or algorithms that might be applicable. But it's not something that is going to happen quickly...

thanks for the feedback

and to add my two thoguths
1. blender3d has tri to quad as a included script (but its a long painfull proscess)
2. hamdling quads by order of proscessing power is much worse than working with tris
