Optimizing Texturing of Layered Surfaces.
Possible uses for layered surface visualization:
Geology
Medical
Meteorology
Oceanography
GIS
Architecture
Experimental setup:
The following 6 images are from the current experiment comparing different grid styles.
Grids have been shown to be a good texture for single surface
visualization, so we use them here.
The actual experiment is run on 3240x2400 resolution screens with
stereo and motion.
Subjects are asked to align direction probes with the top and
bottom surfaces.
Probe accuracy tests how well the subjects can see both surfaces
under different grid conditions.

0) Single Surface

1) Two surfaces, no textures
|
2) Medium grid textures
|
3) Small top grid, big bottom grid
|
4) Big top grid, small bottom grid
|
5) Thin top grid with a translucent background

Follow-up experiment (not finished yet):
We will use what we learn about texture style (relative size, transparency)
to compare two texture types: Projected lines and Principle-curvature lines.
