Replica-Dataset + Bullet Physics crashes

Open soumith opened this issue 4 years ago • 2 comments

🐛 Bug

Any environment from https://github.com/facebookresearch/Replica-Dataset fails to work when enabling Bullet physics.

It works with:

  • not enabling physics
  • using regular kinematic physics, i.e. not Bullet

The exact spot in the logs that fails is:

E0502 04:55:08.508623   972 BulletPhysicsManager.cpp:84] Invalid primitive: Points
E0502 04:55:08.508630   972 BulletPhysicsManager.cpp:101] Cannot load collision mesh, skipping

Sometimes it's Invalid primitive: Points, sometimes BulletPhysicsManager.cpp:99] Invalid primitive -2101531424, etc. It looks like some kind of overflow or stack corruption from a quick glance.

Command

The paths I use:

  • "scene_path": "/remote/Replica-Dataset/data/apartment_0/habitat/mesh_semantic.ply"
  • "physics_config": "/remote/habitat-sim/data/default.phys_scene_config.json"

Expected behavior

The scene loads without crash

We likely need to decimate replica meshes for them to work with physics. We should (if possible) fix whatever bug is causing this but I would be surprised if Bullet was useable with replica meshes in their current form (I think the one you are loading has ~14 million vertices). We had started working on adding a mesh decimation tool here: https://github.com/facebookresearch/habitat-sim/pull/468

@erikwijmans I tried to decimate the room_2 semantic mesh to <500000 vertices but it still doesn't work (roughly same error as OP):

were you able to figure out what is causing this?
