Outdated docs? btGimpactTriangleMeshShape does not exist!

[elethiomel]

I want to collide some moving concave meshes together. By following the diagram on page 16 of the manual, I find that I am supposed to use btGimpactTriangleMeshShape. This does not exist in 2.77! Has it been renamed or replaced?

What is the preferred way of dealing with colliding concave meshes now? For long complicated reasons, I'd rather not go into, I don't want to use convex decompositions.

As I understand it, it's not really possible. Concave meshes can only be static and not dynamic. (i.e. your static environment)

But any concave shape can be split into a number of convex ones?

It's called: btGImpactMeshShape, and you can find it here:

Code: Select all

#include <BulletCollision/Gimpact/btGImpactShape.h>

P.S: It supports moving concave shapes (and supports deformations).
See: http://bulletphysics.org/Bullet/phpBB3/ ... 59&start=0, and http://bulletphysics.org/Bullet/phpBB3/ ... 10&start=0 (by changing the definitions inside the code, you can turn the demo in the second link into a deformation demo like the one in the first link).

Excellent! Thanks for the pointers

Moving as in animated (still 0 mass) or moving as in it has mass and can be a dynamic object? Doesn't elethiomel want dynamic concave objects?

Doesn't elethiomel want dynamic concave objects?

Yes.

Yes.

How very friendly of you.
