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 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. The API was expanded with geometry shaders in OpenGL 3.2, tessellation shaders in OpenGL 4.0 and compute shaders in OpenGL 4.3. These OpenGL APIs are found in the extensions:
For example: Create an FBO and bind it. Attach the color buffer (either as a RenderBuffer or a texture) to the FBO. Attach the depth buffer (either as a RenderBuffer or a texture) to the FBO. Bind the native window FrameBuffer (id=0) Render the texture to screen with a pixel shader, dependent on both the Color information and depth information.
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 Blinn–Phong reflection model, also called the modified Phong reflection model, is a modification developed by Jim Blinn to the Phong reflection model. [1]Blinn–Phong is a shading model used in OpenGL and Direct3D's fixed-function pipeline (before Direct3D 10 and OpenGL 3.1), and is carried out on each vertex as it passes down the graphics pipeline; pixel values between vertices are ...
The ARB and Nvidia established a number of OpenGL extensions to standardize GPU programming: [1] EXT_texture_env_combine - provided a programmable method of combining textures. NV_register_combiners - GeForce 256; NV_vertex_program - GeForce 3; NV_texture_shader - GeForce 3; NV_texture_shader3 - GeForce 4; NV_vertex_program2 - GeForce FX
OpenGL for Embedded Systems (OpenGL ES or GLES) is a subset of the OpenGL computer graphics rendering application programming interface (API) for rendering 2D and 3D computer graphics such as those used by video games, typically hardware-accelerated using a graphics processing unit (GPU). It is designed for embedded systems like smartphones ...
A simple tessellation pipeline rendering a smooth sphere from a crude cubic vertex set using a subdivision method. In computer graphics, tessellation is the dividing of datasets of polygons (sometimes called vertex sets) presenting objects in a scene into suitable structures for rendering.
