Technique implemented:

Technique	Requirements	Implement at
Texture Mapping	Add texture mapped polygonal objects to the environment. Each "object" for grading purposes consists of at least 5 polygons all texture mapped. Different objects require different maps.	House, road
Hierarchical Animated Model	Add a hierarchical, animated model. The model must combine multiple components in a transformation hierarchy. Different models need different hierarchies.	Ferris Wheel
Paramatric Instancing	Add an object described by parameters. You must create multiple instances with different parameters, and each class of model counts for separate points, not each instance.	Trees (cones on sticks)
Sweep Objects	Add an object created as a sweep, either an extrusion or a surface of revolution. The important thing is that it be created by moving some basic shape along a path. The overall object must use at least three different uses of the swept polygon. In other words, something like a cylinder isn't enough, but something like two cylinders joined to form an elbow is.	Trees
Subdivision	An object defined using the modified butterfly scheme or the subdivision rules for Bezier patches. You must include a key press that refines the model, so that we can see the improved quality. This is a special case for extra points. You get 50 for modified butterfly, and another 50 for Bezier. The sphere example from class can help, somewhat, with this.	Small mountain, the stand
Change the Navigation System	The navigation system now is not great. Change it to something better. To get all the points, you must have a mode where the viewer rides the roller-coaster.	Ride the roller coaster, hotkeys to jump to spcific views (good for demos), many possibilities.
