Texture

Texture – is a bitmap ( many color points ) , they give the 3d- models of color , detail and other tangible properties of the surface . Textures are applied to the surface of the landfill . Using textures can create scars on the skin , folds in clothing , small stones and other objects on the surface of walls and soil.
The surface quality of the texture is determined by the minimum number of unit pixels of the texture. The quality of the texture, its solution depends largely on the result of the work on the 3d- scene.
Textures come in different formats , there are RGB, there are alpha (RGBA), monochrome and others.

Creating textures for 3D-model
Currently , there are two basic ways to create texture :
- Production of textures in raster graphics editor (Adobe Photoshop, Gimp, Painter , etc.) from scratch or using pre- raster images ( photographs, drawings , etc.).
- Production of textures in specialized program for drawing textures directly on the surface of three-dimensional model.
Both methods are now widely used . And one , and the second method can obtain high quality texture models
An example of software solutions , which can immediately create textures are packages : MARI, Mudbox, Zbrush, 3DCoat, BodyPaint 3D. These programs address the seams and allow the artist to fully concentrate on the creative process . Also a plus is that these programs not only allow you to create different types of textures , but also instantly see how this or that affects the texture model .

Texture and geometry
Except for procedural textures all other options for the texture (created by 3d- skilled or ready ) is necessary to impose on the object , observing certain rules . Just as virtual tags or labels are applied to the surface texture of the three-dimensional model using a coordinate system.Although the two-dimensional images based on the coordinate system XY, texture superimposed on the object based on the coordinate axes U ( horizontal) and V ( vertical) spanning the surface of the object. Texture mapping method will depend on the type of geometry of your object .

Overlay (texture mapping) and projecting
Texture mapping allows detailing the simplest objects without undue complication of the model geometry .
Texturing (texture mapping) determines the way in obtaining the image texture connects to the surface 3d - model. Overlay depends on the position of an object in space . You can not just apply a texture to the surface, without taking into account the distance to the object and its orientation relative to the viewer. Such a scene would look bad .
The most common method of applying are as follows:
•  Planar imposition-of a direct projection texture from a certain point in three-dimensional space . This method is widely used for applying the texture map to flat surfaces (books, flooring, wall);
•  Cylindrical overlay - texture wraps around the geometry of the model about the same as the label is wrapped around a tin can . This method is used for texturing cylindrical objects
•  spherical overlay - like somewhat cylindrical , but the top and bottom of the structure is closed in some cases, distorting the image. Often have to hide this seam for some secondary object . This method is most suitable for texturing persons , balls , balls , planets, and other similar facilities;
•  The cube overlay -image is projected onto an object with six different directions, each of which corresponds to the plane of symmetry. This method is suitable for texturing objects such as buildings, boxes or interior room.

Tiling (tiling)
To impose on the model of a repeating pattern can create a small image, and then overlay it with a tile placement. This method is much easier and more productive to create a great texture to the entire surface of the object. Furthermore, the mosaic images are small as the memory stores only one element of the mosaic . However, tiling has its disadvantages . It turns out that the images look too uniform , and created , for example, thus more closely resemble grass carpet. In addition, between the elements of the mosaic will seams that need something close . ( But this can be a minus and plus if you, for example , you create a tile in the kitchen. )
In such cases, topical application of a so-called seamless texture. They have a picture with an infinitely repeating pattern , which combined with no defects even if duplicated many times.

Working with layers
To perform complex tasks is not enough alone overlay texture on the surface of the object - then apply multiple textures . For example, you need to create an old log. As the base material can be used tree by assigning appropriate parameters . Then you can add a level showing the rough surface areas , with another layer of moss , third and fourth with cobwebs with dirt and dust. Combining individual textural layers , you can create an infinite variety of options the appearance of your facility.

There are many websites where you can download the texture. One of them is render911.ru
