2D polygon collision test with convex meshes - other proposals?

Hi all,

we’d like to perform collision tests for 2D polygons against other scene objects (and are not interested in any collision response). So far, our plan is to split up the polygons into convex parts and to create convex meshes as trigger shapes.

To use convex mesh objects for this purpose seems like cracking a nut with a sledgehammer.

Do you have other proposals? We didn’t find any shapes directly representing 2D polygons in PhysX.
