Warm-up Questions:
What are the novel contributions from a designer's point of view ?
What can you do with T-splines / T-NURCCs that you could not do before ?
Discuss these questions with your neighbors.
Test-questions:
What is a local knot insertion ? What are the requirements on the surroundings to make this possible ?
What is a "standard" T-spline ? What are its "building blocks"?
Why would one want to render a T-spline as a set of Bézier patches ? How big are those patches ?
What construction motivated the creation of T-splines ? How do T-splines solve the original problem ?
Do you foresee any user-interface issues in those tasks ?
What is a T-NURCC ? What can it do that a Catmull-Clark subdivision surface cannot do ?
Reading Assignments:
Creating Generative Models from Range Images
Hierarchical Mesh Decomposition using Fuzzy Clustering and Cuts
Programming Assignment:
It is time to wrap up your genus-4 texture mapping assignment. Show me what you have been able to accomplish.
Here are some results I have received so far ...
If you can tell where the triangle boundaries are, then the real design objective has not been reached yet.
COURSE PROJECTS:
Acquire background information, plan your path of implementation, try to get some quick and dirty tests going ...
and always keep the overall schedule in mind!
