Problem 1 Our texbook gives a function stripe that generates a stripe texture (see also the lecture notes on texture mapping). Adapt this function to generate a tile texture, giving square tiles any plane that is orthogonal to the X-, Y -, or Z-axis. The size of the square tiles must be controllable.
Problem 2 For planes that are not orthogonal to the X-, Y -, or Z-axis, the texturing function from the previous problem will create non-square (but rectangular) tiles. What can we do to create a square tile texture for such planes?
Problem 3 Explain what bilinear interpolation is (in the context of texture mapping), and explain why we would want to use it.
Problem 4 What is mip-mapping?
Problem 5 Explain the principles of Perlin noise.
Problem 6 How do we map a rectangular image (of, say, a map of the world in mercator projection) onto a sphere?
Problem 7 A 3D triangulated model can be represented by a triangle soup (i.e., a collection of individual triangles), or by a triangle mesh (in which case neighboring triangles share their common vertices). What is the advantage for texturing of the latter representation?
Problem 8 What is the relation between bump mapping and displacement mapping?

Problem 2 We are clipping the polygon above again, but this time with the Weiler-Atherton algorithm. (a) Explain how the graph used by this algorithm is constructed. (b) Give the graph for the polygon and clipping region in the image above. (c) Expla
Problem 1 Our model has an object centered at the point (7, 16, 18). Instead of looking at it from the origin, we want to look at it from behind and above, so we place the origin of our camera at. (10, 20, 30). What is the gaze vector we should speci
2007/2008 Graphics Tutorial 6. Problem 1 The scene below consists of 8 line segments, and the center of projection COP (i.e., the camera view point). The normal vectors of the segments point to the visible side. The dotted lines are not part of the i
