The structure can then be probed to smoothly choose the appropriate level of detail required for the situation. A significant advantage of this technique is the ability to locally vary the detail; for instance, the side of a large object nearer to the view may be presented in high detail, while simultaneously reducing the detail on its distant ...
OpenGL (Open Graphics Library [4]) is a cross-language, cross-platform application programming interface (API) for rendering 2D and 3D vector graphics.The API is typically used to interact with a graphics processing unit (GPU), to achieve hardware-accelerated rendering.
Tessellation can also be used for implementing subdivision surfaces, level of detail scaling and fine displacement mapping. [5] OpenGL 4.0 uses a similar pipeline, where tessellation into triangles is controlled by the Tessellation Control Shader and a set of four tessellation parameters. [6]
The libpf library includes functions for the generation and manipulation of hierarchical scene graphs, scene processing (simulation, intersection, culling, and drawing tasks), level-of-detail management, asynchronous database paging, dynamic coordinate systems, environment models, light points, and so on. This library also provides transparent ...
Level of detail may refer to: Level of detail (writing), the level of abstraction in written works; Level of detail (computer graphics) ...
OpenGL Shading Language (GLSL) is a high-level shading language with a syntax based on the C programming language. It was created by the OpenGL ARB (OpenGL Architecture Review Board) to give developers more direct control of the graphics pipeline without having to use ARB assembly language or hardware-specific languages.
The official OpenGL and OpenGL ES shading language is OpenGL Shading Language, also known as GLSL, and the official Direct3D shading language is High Level Shader Language, also known as HLSL. Cg , a third-party shading language which outputs both OpenGL and Direct3D shaders, was developed by Nvidia ; however since 2012 it has been deprecated.
Typically used for generating lightmaps, normal maps, or low level of detail models. [6] Barycentric coordinates Three-element coordinates of a point inside a triangle. Beam tracing Modification of ray tracing which instead of lines uses pyramid-shaped beams to address some of the shortcomings of traditional ray tracing, such as aliasing. [7]
