3D textures replicate real-world textures and are commonly used with 3D models to make them look more realistic. They are square images that repeat and have three dimensions. Advances in technology have made them more common since 2011.
Three-dimensional (3D) textures are images made to replicate real-world textures, such as veins on a leaf or fur on an animal. Many 3D textures look like two-dimensional (2D) textures when viewed head-on, but there’s a big difference in how the two are created. 3D textures are square images that repeat, so they can be laid over a surface without conflict. These are most commonly used with 3D models, such as in games and animations, to make the models look more realistic or to give them a certain look. When these textures were first created, they weren’t used much, but advances in 3D technology made them a common occurrence as of 2011.
When looking at the 2D and 3D textures head-on, most people won’t be able to tell the difference. Both are made to look like they have a real world texture, and a skilled 2D artist can create textures that look 3D. The difference between the two is not so much the look, but the way the textures are made. While 2D textures have two dimensions, 3D textures are made with three dimensions, commonly known as the X, Y, and Z dimensions. This adds a new layer of information, making textures useful for more applications.
Most 3D textures are square images made to repeat. This means that if the texture image is tiled across a surface, it will appear as one large image. If done correctly, viewers will not see the tiling, because there will be no conflicts. Poorly designed textures won’t scroll, meaning one tile will look awkward next to another tile.
While 3D textures can be used as desktop wallpapers or as embellishments in an image, they are most commonly used with 3D models. When textures are tiled on the models, it will alter the look of the models. For example, if a model has a skirt and pink cotton texture is added over it, the texture will fill in the skirt and make it look more realistic.
In the early days of 3D textures, they were rarely used. This is because memory limitations have made them capable of crashing games and animations or becoming too memory heavy to play properly. Advanced compression technology allows textures to take up less memory, so they can be used without causing these problems. Adding 3D textures can produce realistic results and is usually easier than designing the textured 3D model in your modeling program, so these textures are common.
