Glazing is achieved by unmarking positions and coloring points above a threshold with the type of glazing. Pig s head is a blobby model. Muscles were more ellipsoids. Gloves were tapered cylinders. Trees were 5 slightly different bump-maps of tree bark that were folded to cylinders of varying radii.
Sky is a texture map.
Far background is also a texture map. Ammunition wings and nose were made using parametric surfaces and quadric surfaces. 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.
