Procedural Texture Matching and Transformation
We present a technique for creating a smoothly varying sequence of procedural textures that interpolates between arbitrary input samples of texture. This texture transformation uses a library of procedural shaders and selects the correct shaders and associated parameters to accomplish the task. In general, selecting a procedural texture from a library, or finding the correct parameters to produ...
متن کاملTransformation texture of allotriomorphic ferrite in steel
Many aspects of the crystallographic texture which develops when austenite transforms into martensite or bainite are well established because the process by which the parent lattice is transformed into that of the product is mathematically defined. This is not the case when the ferrite forms by a reconstructive mechanism. The allotriomorphic ferrite nucleates heterogeneously at austenite grain ...
متن کاملDauphiné twinning and texture memory in polycrystalline quartz. Part 3: texture memory during phase transformation
Samples of quartz-bearing rocks were heated above the a (trigonal)–b (hexagonal) phase transformation of quartz (625–950 C) to explore changes in preferred orientation patterns. Textures were measured both in situ and ex situ with neutron, synchrotron X-ray and electron backscatter diffraction. The trigonal–hexagonal phase transformation does not change the orientation of cand a-axes, but posit...
متن کاملThe Transformation between Positional Space and Texture Space
computer graphics, transformations, texture mapping In a 3D graphics application, a common operation is the binding of a 2D texture onto a triangle in a 3D positional space. For light-dependent or view-dependent texture mapping, a need may arise in the graphics pipeline to transform the light or view direction vector into texture space. The affine transformation is unique within the plane of th...
متن کاملTexture Transfer Using Affine Transformation Groups and Patch Boundary Matching
An algorithm for performing texture transfer based on an affine transformation model is presented. Image textures are modelled by placing a single patch of texture, a prototype patch, from which the texture is derived using a set of affine transformations. Overlapping target patches covering the entire image are used and a corresponding set of transformations are found to map the prototype patc...
