Landscape of the week 2

Landscape of the week 2, generation 48, scene 14

This page contains more details on this particular image. Due to the large number of scenes most of them get only rendered at relatively low resolution and quality settings (512x384, no aa). The original image therefore looks a bit jaggy and you might find the scaled down version below better suited to rate the image. The original render is available through the link.

Render time: 0h 8m 27s

POV-Ray source:

This is the source code for the above image, to render you need to have the following tools:

This source code is provided for rendering larger versions of the image for personal use and for enjoyment and education. Commercial use of the source or renders is not allowed.
