Detailed Description

This structure is intended to describe the area and/or volume represented by a ray. In the case of the "rt" program it represents the extent in model coordinates of the prism behind the pixel being rendered.

The r_pt values of the rays indicate the dimensions and location in model space of the ray origin (usually the pixel to be rendered). The r_dir vectors indicate the edges (and thus the shape) of the prism which is formed from the projection of the pixel into space.
