Bill Turner's CPSC 3710 Project


The following picture was drawn using POV-Ray 3.6.

I decided to model the wind farms in the south western part of alberta because I drive past them every time I go to Fernie which is as often as possible in the winter.


One thing I found difficult about modeling this scene was getting the windmill blades to look similar to the picture I found of a turbine on the internet.

I ended up doing it by creating a single blade first. At first this was just a rectangle, however, I was able to use the difference command to cut away pieces of the rectangle so it looked more and more like the blade. I then defined the blade as it's own object so that recreating them would be simple and I would only have to adjust thier positionings. I then created an object composing 3 blades centered around the origin that would display the blades of a turbine so that I could merely translate and rotate the blades anywhere on the screen. I then created the base of the turbine which was fairly simple composing 2 cylinders for the long pole piece and the small front piece that is connected to the blades, and a rectangle for the main structure at the top. I centered the middle of the cylinder at the top of the turbine around the origin so that when I added the blades they would look connected to the main structure without having to do any modifications. That made it easier to make copy's of the turbines and move them around the screen.

Another interesting problem I found was creating and texturing the mountains. I looked at a few textures that people had provided on the web but I couldn't get any of them to look like what I wanted my mountains to look like. In the end I decided to create my own texture for them. This proved difficult as the online material on texture properties isn't easily available and required some digging to find. I still don't think it's as good as I could have made it but time restraints halted any further progress.

The ground and sky were definitely the easiest part of the project. Partly because I found a website that had a good grass texture and sky texture. The sky is just a simple plane with the sky texture added where the ground is slightly more complex. I didn't want the ground to look like just a flat plane as that would be boring and less realistic so I started with a plane and then added a blob object to add some rounding to the plane to look a bit like rolling hills. I was pretty pleased with how it came out in the end.

Some things I would like to change about this project are the turbineblades and the mountains. The turbine blades to me look kind of chunky and not as long as they should be, but I had worked on them for so long and I didn't really notice until I had put the whole picture together that I just didn't have time to go back and fix them up. Also, the mountain range could look a little better, the texture could be improved as well as the shape of the mountain. I think if I had a better program to create the original image that the mountains are created out of then I could have made them look a little more like the mountains we have in the rocky's.

In the end I am quite pleased with how my picture turned out and I had a lot of fun doing it.
