Geometric Deformation-Displacement Maps
Texture mapping, bumpmapping, and displacement maps are central instruments in computer graphics aiming to achieve photo-realistic renderings. In all these techniques, the mapping is typically oneto-one and a single surface location is assigned a single texture color, normal, or displacement. Other specialized techniques have also been developed for the rendering of supplementary surface detail...
متن کاملSubpixel displacement and deformation gradient measurement using digital imageÕspeckle correlation „DISC..
Peng Zhou Kenneth E. Goodson Stanford University Mechanical Engineering Department Stanford, California 94305-3030 E-mail: [email protected] Abstract. Experimental solid mechanics relies heavily on surface displacement and deformation gradient measurements. Digital image/ speckle correlation (DISC) uses digital image processing to resolve displacement and deformation gradient fields. The ...
متن کاملLaser Doppler Displacement Measurement
Existing precision displacement-measuring devices are primarily based on linear encoders (optical or magnetic) or laser interferometers. Most encoders use grating scales and frequency counters, while most interferometers use stabilized lasers and fringe counters. In general, interferometers are more expensive and more accurate than linear encoders. However, there are large gaps in price and per...
متن کاملSliding Deformation: Shape Preserving Per-Vertex Displacement
We present a novel algorithm for deforming a locally smooth polygonal mesh by sliding its vertices over the surface. This sliding deformation creates the visual appearance of texture animation without requiring an explicit global surface parameterization or the overhead of storing texture coordinates. The proposed deformation algorithm can also be employed to slide vertices over the surface to ...
متن کاملParametric Surfaces with Displacement and Deformation
Parametric surfaces are widely used for modeling in CAD systems. However, they pose problems when representing complex macrogeometric features. In order to solve these problems we introduce an extension to parametric surface models that incorporates displacements and deformations. Our extended model retains its original parametric properties, thus allowing easy texture mapping together with a b...
