Travelling Through the Winter Prairies
This picture, drawn from imagination, attemps to represent the cold winters in the Prairies.
A highway, covered with a thin layer of blowing snow particles, cuts through the snow covered
field on both sides (and middle).
Design & Implementation Details
POV-Ray was used to implement this picture. No external image files or processing software
was used. After two days of reading the first few chapters of the POV-Ray manual, and example
code, I was able to start working on this picture.
The picture was build in many stages, each exploring a new feature. I started with adding a basic
camera and source light and a plain representing my world! The following list enumerates the different
stages of implementation:
I did not need to borrow any outside source, except that provided by the POV-Ray 3.6 Macintosh
templates and standard include files.
- road with basic color pigment
- white stipes on road, using a while loop
- fields and higway land seperator (submerged cylinder), with basic colors
- texture (snow and bumps) for road and fields
- atmosphere with cloud texture
- fences (wedges) on both sides, using a while loop
- light posts on both sides, using a while loop
- better lighting (the hardest part, essential step to make things look more realistic)
The POV-Ray source file is available here
