TAILIEUCHUNG - Lecture Computer graphics - Chapter 6: Texture

This chapter presents the following content: Texture mapping, adding visual detail, parameterization, varieties of projections, opengl texture mapping, how to map object to texture? Texture mapping and the opengl pipeline,. | Texture Mapping 1 An Interactive Introduction to OpenGL Programming 1 Texture Mapping Important topic: nearly all objects textured Wood grain, faces, bricks and so on Adds visual detail to scenes Meant as a fun and practically useful lecture Polygonal model With surface texture 2 Adding Visual Detail Basic idea: use images instead of more polygons to represent fine scale color variation 3 Parameterization Q: How do we decide where on the geometry each color from the image should go? 4 geometry + = image texture map Option: Varieties of projections [Paul Bourke] 5 Option: unfold the surface [Piponi2000] 6 Option: make an atlas [Sander2001] charts atlas surface 7 Option: it’s the artist’s problem 8 OpenGL Texture Mapping 9 OpenGL Texture Mapping Apply a 1D, 2D, or 3D image to geometric primitives Uses of Texturing Simulating materials Reducing geometric complexity Image warping Reflections 10 An Interactive Introduction to OpenGL Programming 10 In this section, we’ll discuss texture ( .
