Objective

• Test the impact that many overlapping cubes, all within the camera frustum, have on visibility/occlusion calculations, especially with continuous rotation and shadows enabled.

Solution

• Add a dense cube layout using a static camera, and a toggle for individual cube rotation.

Testing

• I ran the test in several stages, each causing a considerable performance drop.
  • Stage 1: using just the dense layout.
  • Stage 2: using the dense layout with rotation or shadows enabled.
  • Stage 3: using the dense layout with both rotation and shadows enabled.

cargo run --release --example many_cubes -- --layout dense --rotate-cubes --shadows
