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.. 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 . 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:.
