Shaders can be created on the fly from within an application, or read-in as text files, but must be sent to the driver in the form of a string. The set of APIs used to compile, link, and pass parameters to GLSL programs are specified in three OpenGL extensions, and became part of core OpenGL as of OpenGL Version 2.0.
A vertex buffer object (VBO) is an OpenGL feature that provides methods for uploading vertex data (position, normal vector, color, etc.) to the video device for non-immediate-mode rendering. VBOs offer substantial performance gains over immediate mode rendering primarily because the data reside in video device memory rather than system memory ...
The shader assembly language in Direct3D 8 and 9 is the main programming language for vertex and pixel shaders in Shader Model 1.0/1.1, 2.0, and 3.0. It is a direct representation of the intermediate shader bytecode which is passed to the graphics driver for execution.
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.
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. OpenGL and the OpenGL Shading Language; OpenGL ES 3D API for embedded devices.
Perl OpenGL (POGL) is a portable, compiled wrapper library that allows OpenGL to be used in the Perl programming language.. POGL provides support for most OpenGL 2.0 extensions, abstracts operating system specific proc handlers, and supports OpenGL Utility Toolkit (GLUT), a simple cross-platform windowing interface.
The different rendering styles are based on "style modules" that are written in Python programming language. [1] The stand-alone program, which uses OpenGL and the Qt widget toolkit, can render images based on .3ds files. The stand-alone version of Freestyle is not under active development anymore, since 2008.
OpenSceneGraph is an open-source 3D graphics application programming interface (library or framework), [2] used by application developers in fields such as visual simulation, computer games, virtual reality, scientific visualization and modeling.
