Principal direction Swirly direction Uniform direction Experiment 2: Discrimination of subtle surface shape differences, measured in a four alternative forced choice task, is possible at lower thresholds, with line and grid-like patterns, when the texture coordinate system is locally aligned with the principal directions than when it is aligned with a constant uniform direction or with a direction that turns in the surface.
