Three-Dimensional Shape Optimization

by J. W. Hou, S. L. Twu
"... Internal strain-gage balances are often applied to measure the aerodynamic loads acting on the aircraft model in the wind-tunnel test. The balance system consists essentially of one main body and two shoulders elastically interconnected by multibar cages. Designing the cross-sectional geometry of su ..."

model to analyze the stress distribution in the elastic cage and the other is to adopt a three-dimensional shape optimization scheme to design the cross-sectional geometry of the internal strain-gage balance. The design procedure has been completely automated in a computer program. Numerical examples

Three-Dimensional Shape . . .

by Peter Janssen, Rufin Vogels, Guy A. Orban , 2000
"... Neurons in the rostral lower bank of the superior temporal sulcus (TEs), part of the inferior temporal cortex, respond selectively to three-dimensional (3D) shapes. We have investigated how these neurons represent disparity-defined 3D structure. Most neurons were selective for either first-order (di ..."

Multiresolution Modeling of Three-Dimensional Shapes

by Leila De Floriani, Paola Magillo
"... INTRODUCTION Manipulation of models of complex three-dimensional shapes is common in computer graphics and virtual reality, computer-aided-design, geographic information systems, medicine, etc. In this chapter, we deal with geometric models based on spatial decompositions, also known as geometric ..."

Conveying three-dimensional shape with texture

by Sunghee Kim - In APGV ’04, ACM , 2004
"... Studies have shown that although shading can give an image a ”natural” look and is an important shape cue, visual perception of surface shape from shading only is severely limited when the surface is viewed locally without other visual cues such as occluding contours [Mamassian and Kersten 1996; Ere ..."

Three-dimensional shape rendering from multiple images

by Alberto Bartesaghi A, Guillermo Sapiro A, Tom Malzbender B, Dan Gelb
"... A paradigm for automatic three-dimensional shape and geometry rendering from multiple images is introduced in this paper. In particular, non-photorealistic rendering (NPR) techniques in the style of pen-and-ink illustrations are addressed, while the underlying presented ideas can be used in other mo ..."

Directional histogram model for three-dimensional shape similarity

by Xinguo Liu, Robin Sun, Sing Bing, Kang Heung-yeung Shum - Proc. of Conf. on Computer Vision and Pattern Recognition , 2003
"... In this paper, we propose a novel shape representation we call Directional Histogram Model (DHM). It captures the shape variation of an object and is invariant to scaling and rigid transforms. The DHM is computed by first extracting a directional distribution of thickness histogram signatures, which ..."
