This change also requires user scripts to explicitly synchronize changes to physics state to the viewer. The Simulate class was reconfigured so that certain UI events are handled during this sync operation, outside of the render loop on the main thread. These correspond to operations that require access to the full mjModel/mjData. To support other, more interactive operations (e.g. camera movements), a new mjvSceneState struct is introduced which captures only the portion of the physics state required for scene re-rendering. The mjvSceneState is updated from mjModel/mjData during the viewer sync operation, and is significantly cheaper than a full mj_copyModel and mj_copyData.

This simplified humanoid model, introduced in [1], is designed for bipedal locomotion
|
|
behaviours. While several variants of it exist in the wild, this version is based on the model
|
|
in the DeepMind Control Suite [2], which has fairly realistic actuator gains.
