The input to render consists of a single text file containing everything necessary to prepare the image of a scene consisting of coloured spheres, cylinders and triangles. The header records contain information global to the scene being rendered. The header records are followed by individual object records containing coordinate and color specification for the objects in the scene. The required header records of a render input file are described below. Except where noted, each item is on a line by itself in free format.
