ABSTRACT
In this paper, we take a new look at the problem of texturing surfaces so that they can be displayed layered over each other but remain clearly visible. Finding optimal textures that solve this problem is complex because of the perceptual interactions between the visual effects of parameters controlling texture generation. Instead of using controlled experiments to investigate this problem, we use a genetic algorithm based human-in-the-loop parameter space search to build a large database of human-rated textures. This database is then analyzed with a varity of datamining techniques, including clustering, principle component analysis, neural networks, and histogram analysis. We detail this analysis, concluding with a set of guidelines for building strong layered surface textures, and a display of a number of example textures.

Texturing of Layered Surfaces for Optimal Viewing
This paper is a contribution to the literature on perceptually optimal visualizations of layered three-dimensional surfaces. Specifically, we develop guidelines for generating texture patterns, which, when tiled on two overlapped surfaces, minimize ...
Factors influencing the choice of projection textures for displaying layered surfaces
APGV '09: Proceedings of the 6th Symposium on Applied Perception in Graphics and VisualizationWe report on an experiment designed to examine the effect of type and size of projection textures on the ability of human subjects to correctly estimate the surface normal on each of two terrain-like layered surfaces. Normal estimation was determined by ...
Synthesis of progressively-variant textures on arbitrary surfaces
SIGGRAPH '03: ACM SIGGRAPH 2003 PapersWe present an approach for decorating surfaces with progressively-variant textures. Unlike a homogeneous texture, a progressively-variant texture can model local texture variations, including the scale, orientation, color, and shape variations of ...
