Sorry If this was asked for before but today im kinda lazy to search the forums. Rolling Eyes

I would like a traingulation option that tries to make the brush convex. No Idea how hard that is to do.
A simple example is if you move one vertex of a cube and triangulate it should create the edge so that the two triangles are convex.
Admittedly it wont work in every case especially when you go wild modelling a lot of weird shapes, but at the moment I manually make the edges on such cubes and similar to get the convex version.
Also this primarily pertains to the Torque exporter, but I figure triangulation is a DeleD feature so I put it here.

Thanks for the consideration

Marc

Normally, totally convex bodies are the vast minority. If you look at any object in a random scene, you will find that most objects are somehow convex.
I think such a feature would be ambiguous and not worth the effort.

Also, did you know what the turn edge command does? Select two neighbouring triangles that share one edge and see what happens!

No I dint find that command, thanks Ill try. Yeah like I said I dunno how much effort/payoff the feature would be, its more like a nice to have.
And yeah in normal modeling I want concave models, but the dif format only eats convex shapes, hence the idea of adding a check.

If a 3D model is concave (which most models are), making it convex means splitting it up into multiple convex shapes. That's a very complicated process and is exactly what the Torque Exporter currently does. Have you tried it?

Btw, triangles are always convex. Wink
