PPT-CS 4363/6353 Texture Mapping Part II

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 . Fashion. Texture. Blindfold activity. Was it easy or hard to guess what type of fabric it was?. Why? What clues did you have?. Texture. Where is texture found?. In the thickness and appearance of fabric.. 4371.001. Procedural . Animation. Introduction . to Procedural Methods in 3D Computer . Animation. Dr. Midori Kitagawa. In class. Pay attention.

To create models and textures for even fairly small worlds takes ages, if you do it by hand.. Idea: write down the rules of the world, and a program can create the content.. Texture Rubbing . - Fold a sheet of paper into six squares. . - -Make 6 texture rubbings by placing your paper over a surface and rubbing it with a crayon. . -. REMEMBER the object of each texture rubbing AND think of adjectives used to . 2. Basic Stragegy. Three steps to applying a texture. specify the texture. read or generate image. assign to texture. enable texturing. assign texture coordinates to vertices. Proper mapping function is left to application. . . Texture. Texture is an innate property of all surfaces (clouds, trees, bricks, hair etc…). It refers to visual patterns of homogeneity and does not result from the presence of a single color. . To understand and apply the design. elements Color & Texture. . Color. Color is . the quality of an object or substance with respect to light reflected by the object, usually determined visually by measurement of hue, saturation, and brightness of the reflected light; saturation or .

Week 10: . Mapping. Texture mapping. Texture coordinates (UV coordinates). CSS 552 – TOPICS IN RENDERING. 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.. Lead line mapping. Lead line mapping was the earliest form of seafloor mapping; this technique was used in ancient Egypt.. A rope with a weight on the bottom was marked at different “fathoms” and dropped overboard until it hit the sea floor.. 1. Texture Mapping. Applying an image (or a . texture. ) to geometry. 2D images (rectangular). 3D images (volumetric – such as a CAT scan). Adds realism to the scene. A vertex can have:. A 3D position (x, y, z) – 3 floats. 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
