PROBLEM. UV Texture mapping is less flexible due to its tight coupling with the geometry.. Defining UV coordinates for mesh is daunting.. SOLUTION. Projection Texture mapping to the rescue.. What we Know. We can open image files for reading. We can load them into texture buffers. We can link that texture buffer to a variable in the fragment . shader. We can access the texture in the fragment . Obtained from a July, 2014 Summer workshop in Guildford County . Texture Mapping. Texture Mapping. Surfaces may have single colors or they may have multiple color patterns, which are commonly referred to as . Bump Mapping. Many textures are the result of small perturbations in the surface geometry. Modeling these changes would result in an explosion in the number of geometric primitives.. Bump mapping attempts to alter the lighting across a polygon to provide the illusion of texture.. Figure 1. The 3D reconstruction pipeline 4.1Data acquisition We selected the Minolta VIVID 910 as laser scanner, given the scanning precision (up to 0.0008 mm in the fine mode) and flexibility (three
