Notes: TBA
Slides: .ppt file
Further reading:
There is no required reading for this lecture. The notes will be available shortly. The following papers are there for people that are looking to get more advanced material that will not be covered in class.
Interpolation
Geodesic-loxodromes... This is the fancy interpolation for diffusion tensors I mentioned in class.
Bernstein polynomials These are the polynomials used for cubic Bezier curves that I mentioned in class.
Separability
Extensions of the Zwart-Powell Box spline... This is a recent paper that shows a class of trivariate reconstruction techniques that are not separable.
Tensors
Visualization and Analysis of Diffusion Tensor Fields Gordon Kindlmann's PhD. thesis, with everything you ever wanted to know about DTI. Section 2.1 has a good primer in tensor algebra.
8/30: Modeling Data for Visualization
Lecturer: Carlos
Topics: Geometry Processing: Reconstruction and meshing; Simplification; Smoothing; Other Filtering algorithms
Notes: .pdf file. If you want to print these, you might want to wait for a week or two, until I finish polishing them.
Slides: .ppt file These slides include simplificatin algorithms, which I'll talk about next week.

Further Reading: There is no required reading for this lecture. For those interested in more depth, the following books are very useful:
- The Elements of Graphing Data. William S. Cleveland, Hobart Press, 2nd Edition, 1994.
- Visualizing Data. William S. Cleveland, Hobart Press, 1993.
- The Visual Display of Quantitative Information. Edward R. Tufte, Graphics Press, 2001.

Notes:
Slides: Plotting2.pdf
Vistrails: PlottingVistrails.zip - Unzip this file in the examples directory of your VisTrails installation and it will add the vistrails along with their data sets (in the data directory). If you don't have permission to write to this directory (CADE users), then unzip the file where you want. Just be aware that in this case the paths for the data files may not be correct for most vistrails and will need to be fixed before they will execute properly.
