texture mapping

texture mapping

In computer graphics, the application of a type of surface to a 3D image. A texture can be uniform, such as a brick wall, or irregular, such as wood grain or marble. The common method is to create a 2D bitmapped image of the texture, called a "texture map," which is then "wrapped around" the 3D object. An alternate method is to compute the texture entirely via mathematics instead of bitmaps. The latter method is not widely used, but can create more precise textures especially if there is great depth to the objects being textured. See texel, point sampling, bilinear interpolation, trilinear interpolation, MIP mapping, procedural texture and volumetric texture.


Bitmap Texture Mapping
Each pixel in the 3D object is mapped to a corresponding texel in the 2D texture map. (Original illustration courtesy of Intergraph Computer Systems.)

The application is mapping and navigation, 3D mobile mapping, 3D projection mapping, 3D laser mapping, 3D texture mapping, 3D video mapping, and others.
These steps can be performed manually on a given photoset within open-source software, such as Visual SFM (Changchang Wu, Seattle, Washington), for camera alignment and dense point cloud generation (Figure 1, B through D); and MeshLab (CNR-ISTI, Pisa, Italy), using Poisson surface reconstruction for mesh rendering and projection of active raster colors for texture mapping (Figure 1, E).
Each block contains a group of cores, a scheduler, a register file, instruction cache, texture and L1 cache, and texture mapping units.
The software has recently been upgraded to version 3.0, which includes 14 new toots for fabrication, 3-D printing, NURBS modeling, shape editing, texture mapping, and component management.
In addition to the historical research there is a detailed technical investigation into Rembrandt's methods and materials, using infrared reflectography, polynomial texture mapping, dendrochronology and x-radiography, allowing a clearer path for the interpretation of the painting, in whose 'making' there were evidently a number of stages.
"I needed the ZPrinterA[R], <http://www.zcorp.com/en/Products/3D-Printers/spage.aspx> which not only accommodates large sizes but, because of its unique color capability, is the only way to accurately reproduce the highly detailed texture mapping used in these computer models.
VISI Modeling is the base application and delivers CAD enhancements that include an updated GUI, new blending capabilities, support for the widely adopted JT Open format, improved 3D annotation, advanced profile offset, graphical texture mapping and a new 'Assembly Tool Manager' to handle multi-level tool structures.
Among the topics are modeling and analyzing an arc weld inverter based on double closed-loop control, an interface based on mouth open/close motions, dynamic responses for viscoelastic shock absorbers to protect a finger under impact force, laser Doppler velocimetery using integrated waveguide technology, a novel technique for detecting triboelectricity under perfect non-contact conditions, erecting building facades in urban space and texture mapping to a three-dimensional polygon map using an in-vehicle camera, recovering the shape of a specular object in the presence of inter-reflection, and the integral and direct representation of nonlinear inverse mapping.

Paint 3D is also the original development ground and authoring tool for Ptex, Disney's revolutionary open source texture mapping system that eliminates the need for UV mapping and efficiently stores hundreds of thousands of images in a single file.
Other subjects include a new clustering methodology for group photos taken by multiple travelers, a method for locating road intersections in aerial images, a probabilistic model for automatic image annotation and retrieval, and low-overhead texture mapping on 3D models.
Using the available techniques, the HXN can also perform crystallographic phase determination, crystallographic texture mapping, and speckle interferometry.
