Photorealistic TexturePrinciples of Photo-real 3D IIIn 3D computer graphics, a texture is a digitalimage applied to the surface of a 3D model bytexture mapping to give the model a morerealistic appearance.Often, the image is a photograph of a "real"texture, such as wood grain.


Photorealistic TexturePrinciples of Photo-real 3D IIStochastic textures look like noise (color dots),that are randomly scattered over the image,barely specified by the attributes minimumand maximum brightness and average color.Many textures look like stochastic textureswhen viewed from a distance.Structured textures. These textures look likesomewhat regular patterns.

Photorealistic TexturePrinciples of Photo-real 3D IINothing makes an objectlook more artificial that aflawless surface. Even brandnew objects haveoccasional subtle flaws.Computer graphics havemade it far too easy tocreate perfect objects. Theproblem is that reality isn'tperfect. It's important thatyou add a little wear andtear to your objects to makethem realistic.

Photorealistic TexturePrinciples of Photo-real 3D IIIt's not that we are lazy anddon't clean our houses. It's justa fact of life, dirt is everywhereand we can't escape it -- unlesswe live in a plastic bubble.


Photorealistic TexturePrinciples of Photo-real 3D IIAs you can see, aging is a critical aspect of aphoto realistic 3D scene. Before you add theaging, take some time to explore your sceneto find out what kind of aging to add.Where it is coming from?How it's being spread.It may seem like a lot of work but it's actuallya lot of fun. How often do you get theopportunity to make a mess without having toclean it up?
