MotrixSim Backend

motrix-env-motrixsim binds the backend-neutral sim boundary of motrix-env-core to the MotrixSim simulator:

  • MotrixSimSceneCompiler — compiles a declarative SceneCfg into a MotrixSim model;
  • MotrixSimBackend — the live SimBackend (reads, writes, stepping, reset, rendering);
  • TorchEnv — the torch-tensor environment frontend for MotrixSim.

Installing the package registers the backend under the name "motrixsim" through the motrix_env.sim_backends entry-point group, and marks it as the default simulator. Importing motrix_env_motrixsim is cheap; the native motrixsim module loads only when a deep module is imported.

from motrix_env_motrixsim.compiler import build_scene_model

model = build_scene_model(scene_cfg)
