Rings on the ground = the 32 scan lines.
Dark wedges behind objects = occlusion shadows: the sensor cannot see behind things. Click the ground to move the sensor — watch the shadows move with it.

Now untick "show the world": this point cloud is ALL the car knows. No surfaces, no objects — just points.

Spin faster and the rings get sparser: the laser fires at a fixed rate, so a quicker revolution contains fewer pulses. Real sensors spin at 10–20 Hz and fire ~100× faster than this demo.
