The clip coordinate system is a homogeneous coordinate system in the graphics pipeline that is used for clipping. [1]Objects' coordinates are transformed via a projection transformation into clip coordinates, at which point it may be efficiently determined on an object-by-object basis which portions of the objects will be visible to the user.
The computer graphics pipeline, also known as the rendering pipeline, or graphics pipeline, is a framework within computer graphics that outlines the necessary procedures for transforming a three-dimensional (3D) scene into a two-dimensional (2D) representation on a screen. [1]
The objects in 3D computer graphics are often referred to as 3D models. Unlike the rendered image, a model's data is contained within a graphical data file. A 3D model is a mathematical representation of any three-dimensional object; a model is not technically a graphic until it is displayed.
Beyond projection of vertices & 2D clipping, near clipping is required to correctly rasterise 3D primitives; this is because vertices may have been projected behind the eye. Near clipping ensures that all the vertices used have valid 2D coordinates. Together with far-clipping it also helps prevent overflow of depth-buffer values.
These APIs for 3D computer graphics are particularly popular: ANGLE, web browsers graphics engine, a cross-platform translator of OpenGL ES calls to DirectX, OpenGL, or Vulkan API calls. Direct3D (a subset of DirectX) Glide a defunct 3D graphics API developed by 3dfx Interactive. Mantle developed by AMD. Metal developed by Apple.
In 3D computer graphics, normal mapping, or Dot3 bump mapping, is a texture mapping technique used for faking the lighting of bumps and dents – an implementation of bump mapping. It is used to add details without using more polygons . [ 1 ]
Texture mapping [1] [2] [3] is a term used in computer graphics to describe how 2D images are projected onto 3D models. The most common variant is the UV unwrap, which can be described as an inverse paper cutout, where the surfaces of a 3D model is cut apart so that it can be unfolded into a 2D coordinate space (UV Space).
3Dc (FourCC : ATI2), also known as DXN, BC5, or Block Compression 5 is a lossy data compression algorithm for normal maps invented and first implemented by ATI.It builds upon the earlier DXT5 algorithm and is an open standard. 3Dc is now implemented by both ATI and Nvidia.
