To create the propeller s motion blur, we added more rotors and a semi-transparent flattened ellipsoid. Pig s breathing motion is based on a rectified sine wave that is damped after the second breath. Donut changes to explosion color and opacity goes to zero to simulate incineration. Bruce is introduced in the background at about the same time the bushes get hidden by the flame and vanishes to reveal a clearing in the forest. Flowery shirt is a parametrically defined Texture Map.
Slashes are parametrically altered cones that changed intensity as the slash lengthened.
These cones are also color-mapped.
