Texturemapping
Texture mapping is a graphic design process that involves wrapping a 2D texture map around a 3D object to give it a surface texture. This technique is commonly used in 3D graphics and film visual effects. It involves correctly positioning the texture to account for the object's 3D geometry. Avatar extensively used texture mapping to create its virtual worlds and characters. Photographers can also use texture mapping by layering texture images over photos and adjusting settings like blending modes, hue, warp tools to enhance images. Students are assigned to find textures and photos to practice applying different textures as overlays and manipulating layers.

- 2. What is texturemapping? • Texture mapping is a graphic design process in which a two-dimensional (2-D) surface, called a texture map, is "wrapped around" a three- dimensional (3-D) object. • The 3-D object acquires a surface texture similar to that of the 2-D surface. • Perspective: correct texturing accounts for the vertices' positions in 3D space
- 3. Cinematic Uses • Boxoffice record-breaking Avatar was a hugely challenging film to make with a staggering 2500 visual effects (VFX) shots that include both performance- capture characters and models of enormous scale • Textures played a critical role in creating a rich and varied set of assets • Before painting a character or asset, the texture team would look at reference material and concept art
- 4. Texture Mapping Photography •We can apply texture mapping, traditionally used for 3D graphics, to photography • We can use LAYER MASK and a layer blending modes to add a different texture to an object • To create the texture effect, you'll need at least two images
