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 ...
OpenGL ES 1.1 added features such as mandatory support for multitexture, better multitexture support (including combiners and dot product texture operations), automatic mipmap generation, vertex buffer objects, state queries, user clip planes, and greater control over point rendering. [3]
Vertex buffer A rendering resource managed by a rendering API holding vertex data. May be connected by primitive indices to assemble rendering primitives such as triangle strips. Also known as a Vertex buffer object in OpenGL. Vertex cache A specialised read-only cache in a graphics processing unit for buffering indexed vertex buffer reads ...
A vertex (plural: vertices) is a point in the world. Many points are used to join the surfaces. ... OpenGL prefers column vectors, ... This buffer often has only a ...
Automatic management of Vertex Buffer Objects. Extensive framebuffer objects support. Provided scene managers: generic hierarchical volume tree, KdTree, portal-based scene graph. High quality unicode text rendering and text manipulation functions and classes. GLSL based C++ advanced vector/matrix library.
To draw a triangle strip using immediate mode OpenGL, glBegin must be passed the argument GL_TRIANGLE_STRIP, which notifies OpenGL a triangle strip is about to be drawn. The glVertex * family of functions specify the coordinates for each vertex in the triangle strip. For more information, consult The OpenGL Redbook. [3]
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.
Example of coexistence with immediate mode in the same library is OpenGL. [dubious – discuss] [failed verification] [10] OpenGL has immediate mode functions that can use previously defined server side objects (textures, vertex buffers and index buffers, shaders, etc.) without resending unchanged data.
