Problem Set 6

This assignment is due 18 October 2022.

This is intended to be an INDIVIDUAL exercise. Please, no assistance from other students.

1. (10 points) Do exercise 7.1 on page 427 of your text.

   How is an image produced with an environment map different from a ray-traced image of the same scene?

2. (15 points) Do exercise 7.3 on page 428 of your text.

   We can attempt to display sampled data by simply plotting the points and letting the human visual system merge the points into shapes. Why is this technique dangerous if the data are close to the Nyquist limit?

3. (15 points) Do exercise 7.9 on page 428 of your text.

   Consider a scene composed of simple objects, such as parallelepipeds, that are instanced at different sizes. Suppose you have a single texture map and you are asked to map this texture to all the objects. How would you map the texture so that the pattern would be the same size on each face of each object?
