Modeling telescopic heliostat arrays with Povray

Computer-generated view of a telescopic heliostat array with the secondary mirrors represented by spheres.

I am starting on 3D modeling telescopic heliostat arrays using the povray software. This is an early result with the locations of the secondary mirrors represented by spheres. The heliostats are 6x and f-3.0; the sun is at 45° elevation.

A telephoto view of the same array from the direction of the sun, but a mere 50 primary focal lengths away. From the sun the entire field would look like the dark center of this view.

View from under the gimbaled primaries of a telescopic heliostat field. Sun is at zenith. These primaries are mirrored on their reverse side as well.
