A texture map [5] [6] is an image applied (mapped) to the surface of a shape or polygon. [7] This may be a bitmap image or a procedural texture.They may be stored in common image file formats, referenced by 3D model formats or material definitions, and assembled into resource bundles.
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 ...
UVW mapping is a mathematical technique for coordinate mapping. [1] In computer graphics, it most commonly maps an object's surface in to a solid texture with UVW coordinates in , in contrast to UV mapping, which maps surfaces in to an image with UV coordinates in .
Polynomial texture mapping (PTM), also known as Reflectance Transformation Imaging (RTI), is a technique of imaging and interactively displaying objects under varying lighting conditions to reveal surface phenomena.
Texture units in a video card take a texture and 'map' it to a piece of geometry. That is, they wrap the texture around the geometry and produce textured pixels which can then be written to the screen. Textures can be an actual image, a lightmap, or even normal maps for advanced surface lighting effects.
It can use any external image for the basis of the bump map or alternatively the user can pick out the hue, saturation, luminance or red, green, or blue channel of the current image. It can then offset, scale and rotate the texture map, control its lighting, and even blend in a reflection map.
[circular definition] By using the map as a guide when creating a new 2-D image, the colors of the 2-D image can be applied to the original 3-D model. LSCM is used in computer graphics as a method of producing a UV map from a polygonal mesh to a texture map such that the shape of the polygons as mapped to the texture is relatively undistorted.
Projective texture mapping is a method of texture mapping that allows a textured image to be projected onto a scene as if by a slide projector. Projective texture mapping is useful in a variety of lighting techniques and it is the starting point for shadow mapping .
