Preparation: Study:  Texture Synthesis over Arbitrary Manifold Surfaces

Warm-Up:  Answer some key questions about today's paper

Paper Presentation: 

Soham leads the discussion on: Texture Synthesis over Arbitrary Manifold Surfaces 

  1. What is the key problem that prevents the application of Wei and Levoy's original texture synthesis scheme
    to be applied to a smooth object of  arbitrary genus ?

  2. What are the key advantages of the new scheme ?

  3. What are the key differences between the way that Wei and Levoy put texture onto a surface
    and the way that you tried to do it on your mug ?

  4. How would you choose texture directions on you mug if you had a 2-way directional texture ?

  5. How do Wei and Levoy define a "vertex neighborhood" ?

  6. How does the "Image Pyramid" work ?

Follow-up: There is a way of combing a sphere with only a single point singularity!


Assignments for Tue. Nov. 6, 2012:

Study: DF'00:  Adaptively Sampled Distance Fields

and then try to answer the following four questions, sending me e-mail before 5pm on Monday, Nov. 5, 2012.

1.) In the top-down approach for creating subdivided ADF cells, what are the exact tests performed ?

2.) How is the gradient of the distance field computed ?

3.) In comparing the number of elements in Figures 4b and 4d, are the authors doing a fair comparison ?
     How might they be making the ADF approach look particularly good in this example ?

4.) Name a couple of application domains that profit from the ADF approach of shape representation.
