Translating the essence of cave painting to the rapid prototyping machine.
• Thesis defense at 9:20 in Lubrano
• Process overview
• What worked?
• Complete models made of the guitarrista
• What didn’t work?
• Depth Fields. Many strokes are dropped.
• Thesis defense at 9:20 in Lubrano
• Where could this eventually live?

Graphic designers exhibit similar results as previous users in the computerized TYPE ID task:
Can you determine the type of a given critical point (attracting focus, repelling focus, attracting node, repelling node, saddle)?

Graphic designers also critiqued and ranked the visualization methods w.r.t. their ability to accurately and quickly enable a user to perform the TYPE ID task
The table shows that these rankings (1=“good”...6=“bad”) are not precise predictors of user performance
This lack of a solid correlation between the designer rankings and actual user performance on the TYPE ID task may have several explanations:
Lack of any variance on user performance between the 6 visualization methods
Designers were forced to rank-order methods that actually do not elicit different user behaviors
Designers noticed differences in the methods that were not apparent to the user
The TYPE ID task was so simple that it did not force subjects to utilize the full potential of the visualization methods
Designers are not good at predicting how well 2D vector visualization methods facilitate users’ understanding of the underlying data
Had to put this in for thoroughness, but I do not think this is the case

Idea #1
We could generate a 3D model of the source stroke by scanning or Computer Vision, then analyze its statistics to derive a new 3D brushstroke model for the resulting strokes.
Idea #2Simulate real paint and brushstroke using Fluid Dynamics….
How to get a real, nice-looking brushstroke?
