GPU raycasting tutorial using the OpenGL API
Category: Developers • Permalink
Jan 31, 2007
GPU raycasting is a technique that can be used to render volumetric effects in real time. GPU raycasting is well suited for modern graphics cards, different optimizations and visual enhancements are easy to implement. This tutorial explains how to implement a simple GPU raycaster using the OpenGL API with vertex-fragment shaders and Nvidia’s CG. Includes demo with source.
GLCaml Objective Caml interface to OpenGL API

Jan 29, 2007
GLCaml is an Objective Caml (general-purpose programming language) interface for OpenGL versions 1.1, through 2.1, plus extensions. It is intended as a compact drop-in direct, dynamic binding to the OpenGL API. An OCaml SDL binding is provided as well, along with texture-map scaling functions, texture mip-map generators, and a bitmapped font library.
jslibs native libraries and OpenGL API wrapper for the SpiderMonkey Javascript engine

jslibs is a set of general-purpose native libraries for the SpiderMonkey Javascript engine (Mozilla’s C implementation of JavaScript). Some of these modules are simple wrappers to familiar libraries including the OpenGL API. Other modules provide tools for Javascript programming. Modules can be used in any project that embeds SpiderMonkey.

The Tao Framework provides .NET and Mono bindings to various native libraries, including OpenGL, SDL, Cg, DevIL, ODE, OpenAL, Lua, and more. The new v2.0 RC1 includes bindings for OpenGL 2.1, FreeGLUT, OpenAL GLFW, CG 1.4, and SDL. The Tao.OpenGl binding has been completely rewritten with native bindings to OpenGL 2.1.
GLEX OpenGL API extension specification parser

GLEX is an Open Source project that implements an OpenGL extension specification parser in PHP that can be used both online (using the OpenGL Extension Registry) or from the command line. It reads the specification text file either from a file or URL and outputs a minimal set of compact C source files that can be easily added to existing projects to initialize the desired extension. It is intended to be used when only a small number of extensions are required and code size should be minimized and to complement existing extension initialization libraries like GLEW or GLee. This makes it a good tool to test new extensions for which a specification is available but which are not yet included in any of the above libraries. (also available at mirror site)
Soft shadows dynamic branching benchmark v1.5.4 using OpenGL 2.0
Category: Developers • Permalink
Jan 22, 2007
This benchmark stresses the pixel pipelines by rendering a scene with soft shadows using a 7x7 kernel filter. The benchmark uses an OpenGL 2.0 codepath as well as OpenGL Shading Language shaders to render the soft shadows. You can enable or disable dynamic branching in the pixel shader in order to see the impact on the performances. Very handy to quickly benchmark a graphics card.
