Test#3: Open-book programming test.

1. No collaboration with others online or not during the test.

2. You can use your own code and/or adapt code from the book, but you are not allowed to borrow code from the internet.

Part I: Texture mapping: Reuse what you have for the modeling of the bus scene in Test #2 earlier this semester to make the following things happen:

1. Examine the texture mapping in Plate 30 in the appendix of OpenGL red book. It appears that 4 texture patterns are mapped onto the 4 quads (rectangles) to represent the grass in the foreground, the lower part of the mountain in the background, the higher part of the mountain in the background, and the sky on the top of the scene. Make similar things happen in your modeling of the bus scene by using texture mapping onto 4 quads (rectangles) to create grass on the ground, the lower part and the higher part of the mountains with different plant vegetation patterns, and the sky.

2. Add a keyboard toggle such that when the user presses the key t the texture mapping done above is toggled on and off.

Part II: Fog:

1. Incorporate fog around the mountain of the bus scene to create an effect somewhat similar to Plate 31 in the appendix of OpenGL red book.

2. Add a keyboard toggle such that when the user presses the key f the foggy effect done above is toggled on and off.

Part III: Blending (not needed for the 1^st submission, only required for the 2^nd submission):

1. Think about the sail of a windmill. Incorporate at least 2 translucent/transparent rotating sails close to the camera in the bus scene to create so that theuser can partially see through the sails by using the blending techniques as you have seen in in alpha.cpp.

2. Add a keyboard toggle such that when the user presses the key b the blending effects of the sails done above is toggled on and off.

· 1st submission: By the end of the class, submit the source code file(s) and your test report under Canvas to show what you are able to accomplish in 75 minutes.

· 2nd submission: By 11:50pm Saturday 05/09/2015, submit the final version of the source code file(s) and your test report under Canvas to show what you are able to accomplish in the end.
