Hey,
I wanted to start a small project which has 2D softbodies(e.g. a wobbly ground in a sidescroller). Since the common libraries like box2d and chipmunk don't support softbodies, my decision has fallen towards bullet, since it has 2D support.
Well I worked through the Planar2D example and saw that only 2d boxes and convex shapes are supported(btBox2dShape, btConvex2dShape), this leads to the first question:
Are concave 2d objects(e.g. polygons) supported?
And the second question: is it possible to use the 3d softbodies in a 2d environment?
best regards
Philipp
