  2. Back-face culling - Wikipedia

    en.wikipedia.org/wiki/Back-face_culling

    On the left a model without back-face culling; on the right the same model with back-faces removed. Because the polygons do not form a closed solid, differences can be seen. In computer graphics, back-face culling determines whether a polygon that is part of a solid needs to be drawn.

  3. UV mapping - Wikipedia

    en.wikipedia.org/wiki/UV_mapping

    UV mapping is the 3D modeling process of projecting a 3D model's surface to a 2D image for texture mapping. The letters "U" and "V" denote the axes of the 2D texture because "X", "Y", and "Z" are already used to denote the axes of the 3D object in model space, while "W" (in addition to XYZ) is used in calculating quaternion rotations, a common ...

  4. Texture mapping - Wikipedia

    en.wikipedia.org/wiki/Texture_mapping

    Texture streaming is a means of using data streams for textures, where each texture is available in two or more different resolutions, as to determine which texture should be loaded into memory and used based on draw distance from the viewer and how much memory is available for textures. Texture streaming allows a rendering engine to use low ...

  5. Bitmap textures - Wikipedia

    en.wikipedia.org/wiki/Bitmap_textures

    They are commonly used to give texture to models, renders, or environments in animation or video games. [1] These textures are created by artists or designers using bitmap editor software such as Adobe Photoshop [ 2 ] or GIMP , [ 3 ] or simply by scanning an image and, if necessary, retouching it on a personal computer .

  6. 3D modeling software - Wikipedia

    en.wikipedia.org/wiki/3D_modeling

    The 3D model can be physically created using 3D printing devices that form 2D layers of the model with three-dimensional material, one layer at a time. Without a 3D model, a 3D print is not possible. 3D modeling software is a class of 3D computer graphics software used to produce 3D models. Individual programs of this class are called modeling ...

  7. Multiple Render Targets - Wikipedia

    en.wikipedia.org/wiki/Multiple_Render_Targets

    In the field of 3D computer graphics, Multiple Render Targets, or MRT, is a feature of modern graphics processing units (GPUs) that allows the programmable rendering pipeline to render images to multiple render target textures at once. These textures can then be used as inputs to other shaders or as texture maps applied to 3D models.

  8. Mipmap - Wikipedia

    en.wikipedia.org/wiki/Mipmap

    Rendering speed increases since the number of texture pixels being processed per display pixel can be much lower for similar results with the simpler mipmap textures. If using a limited number of texture samples per display pixel (as is the case with bilinear filtering ) then artifacts are reduced since the mipmap images are effectively already ...

  9. Texture filtering - Wikipedia

    en.wikipedia.org/wiki/Texture_filtering

    During the texture mapping process for any arbitrary 3D surface, a texture lookup takes place to find out where on the texture each pixel center falls. For texture-mapped polygonal surfaces composed of triangles typical of most surfaces in 3D games and movies, every pixel (or subordinate pixel sample) of that surface will be associated with some triangle(s) and a set of barycentric coordinates ...
