This submission improves upon the demo submitted here:
See the associated demo to see how to get started building the wind turbine in VRML from scratch.
To add realism to the scene, the terrain was modeled in Blender, a free 3D tool for authoring powerful 3D scenes:
The tutorial that was referenced for creating the mountains is available here:
Use the Export to VRML feature to bring the Blender file into the VRML format.
The sky was modeled as a half-hemisphere with texturing. The images used for the textures were photographed by the author. It is highly recommended that you explore with your camera to get better texture images.
Also, observe the position of the lighting to create the effect of shadows on the landscape (effect created due to light not reaching the leeward side)
