Effective computer graphic applications should accurately convey three dimensional shape. Previously, we investigated the contributions of shading and contour, specular highlights, and light source direction to three dimensional shape perception. Our experiments use displays of convex solid objects based on the superquadric parameterization, permitting(More)
Three-dimensional computer graphic displays contain the information that viewers use to understand the shapes of depicted objects. We have devised techniques for carrying out experiments that examine the factors that influence the accuracy of this shape understanding. We construct simple convex objects using the superquadric equation. The objects are(More)
