Hi again! For a while I've been running in to an issue with seemingly random crashes when allocating or freeing memory. I think I've finally tracked it down to having...

Are different dworlds threadsafe?

Can I use two different dworlds from the same PhysicsCommon on different threads with no mutexing?

Get all objects overlapped by sphere

1

I'd like to find all objects within a sphere in the dworld. Best way I've found is to PhysicsWorld::testOverlap but that involves adding a CollisionShape to a Body to get...

Convex mesh creation and collisions

Here is my code for creating a convex mesh: ```cpp void Entity::createConvexMesh() { reactphysics3d::Transform transform = reactphysics3d::Transform::identity(); body = scene_p->physicsWorld->createRigidBody(transform); vec3 *evertices = (vec3 *)(*this).operator()(EntityQuanta::Vertex); ivec3 *eindices = (ivec3 *)(*this).operator()(EntityQuanta::Indice);...

Physics world scaling

Hey, my question is a bit of an odd one. Is it possible to, for example, vertically scale all physics objects? I'm trying to recreate physics of a fairly old...
