Supervising geometry from two information sources:
From vision: dense, affected by occlusion
From physics: sparse, can be hypothesized anywhere
known environment
known robot location

Desired controller properties:
- contact-implicit
- real-time
- globally effective
At every control loop, our algorithm does:
- Sample starting locations for our robot.
- Compute local CI-MPC plan from each location.
- Choose whether to run CI-MPC now or move elsewhere.
