Texture Assignment

Required Figure

• Texture-map some textures on the walls and roof of the barn. Use wood or brick or some kind of reasonable "wall-like" material for the sides, and similarly for the roof.
• Note that the front and back of the barn are pentagons. You'll have to figure out the best way to deal with that.
• Use the "modulate" mode for the surfaces and put a light in your scene so that you can see the interaction of lighting with texture-mapping.
• Don't forget the surface normals for the faces of the barn!
• If you'd like, you can texture-map, using "decal," on one face of the barn, just for fun. You won't have to worry about surface normals on this unlit face.

Your target is:

~cs307/pub/assignments/texture-barn

Things to note about the barn:

• You can toggle texture-mapping to see the underlying shading by using the "t" key.
• If you like my textures, you can use the ones in that directory (siding*.ppm and roofing*.ppm). I just found them online using a Google search for images; you can probably find better ones.

Please name your finished program texbarn.cc and drop it using the "drop" command.

Remember: When you drop this assignment, you must also drop the textures you used, unless you use ones from the tw/textures/ directory.

Creative Figure

Create a scene, or modify some existing scene from your semester project, so that there are some texture-mapped surfaces. I'd like you to use material and lighting and I'd like to see examples of both decal and modulate, since the latter is pretty interesting to try to control. A really good project would also load several textures and use binding.

Remember: When you drop this assignment, you must also drop the textures you used.
