VIEWING RECOMMENDATIONS: Tested in Windows Media Player and mpeg_play DESCRIPTION OF HOW THIS ANIMATION WAS CREATED: All frames were rendered at 320x240 with anti-aliasing. The full source is in the zip file. The main elements are as follows: - Scene The salt-flats are a plane with a random texture. As things speed-up, the texture is scaled larger in the direction of motion to simulate motion blur. The track markings on the flats are polygons and text objects placed just above the surface. The surrounding hills are height fields which have been rendered into a separate file. - Car The body is made from cylinder blobs with scaled spheres for the nose cone and the canopy. The 'wings' and tail plane are cones which are scaled and then cropped. The rocket flame is media with a random density pattern which is translated to give a flickering effect. The image distortion when it first starts up is done by using the ripples normal pattern in the camera normal. The exhaust trail is a line of spheres with a random transparent pattern, with the sphere sizes set by a random walk (ie. each size is the previous size plus a small random change). The tyres are scaled spheres which are transparent and filled with dense media to give a solid look. This allows the density to be reduced to give a softer 'motion blur' look to the tyres at speed. - Cockpit Forwards view The cockpit is made from standard primitives. The arms and hands are made using a limb macro which creates a line of randomly displaced spheres with random textures which almost looks like cloth if you stand far enough back. - Cockpit Backwards View The body and arms are made using the limb macro described above. The helmet is two cropped spheres with a cut out and an image map for the face.
