Gravity - 1mil particles - hands are gravity points - color is determined by last velocity direction controls - joystick y-axis is attraction (up to repel, down to attract) - grab with one hand (middle finger grip) to rotate and move environment - grab with two hands and move hands closer and further apart to zoom - hold B and Y buttons to make that controller's velocity affect nearby particles Swarm - 60k particles - 3 flocking forces: alignment, cohesion, separation - hands are force-fields that can capture particles controls - joystick y-axis temporarily changes forcefield radius - holding down trigger (index) and moving joystick permanently changes forcefield radius - grab with one hand (middle finger grip) to rotate and move environment - grab with two hands and move hands closer and further apart to zoom - B and Y buttons toggle forcefield for that hand - A button pauses and plays the flocking simulation
