The EXT_framebuffer_object (FBO) extension is the long awaited render-to-texture extension developed by the ARB’s “superbuffers” working group. It defines a simple interface for drawing to rendering destinations other than the buffers provided to the GL by the window-system and enables a form of “offscreen” rendering and “render to texture”. This specification is the evolution of an effort that has its roots in draft proposals such as uberbuffers and render_target.
OpenGL Shading Language tutorial adds sections on the graphics pipeline, data types, and a first sim
This OpenGL Shading Language tutorial has been enhanced with new sections on the graphics pipeline, communication from the OpenGL application to the shaders, data types, variables, statements, functions, and a simple first example.
PLIB is an open source, portable game library that includes an audio driver, GUI widgets, a complete OpenGL API-based 3D engine and scene graph, font rendering using OpenGL texture mapped fonts, a simple Windowing library, a game scripting language, a GUI, networking, 3D math library and a utility library. Each library component is fairly independent of the others. The new v1.8.4 adds an Open Inventor exporter, optimizations, ASC import/export and Linux joystick support.
modo is an advanced OpenGL-based polyogonal and subdivision surface modeler. The new Modo 102 add UV sew, bend tool, LUA scripting support; UV to EPS export, generating a quadrangular polygon from three vertices, OpenGL API rendering transparency, and more.
AgentFX is a platform independent 3D-engine written in Java and uses the OpenGL API to deliver high-end features like real-time shadow volumes and dynamic lights. The new v2.1 includes a rewrite and major update of the scengraph and rendering engine, improved support for vertex and pixel shaders using Cg-language, resource-based Input/Out for use with Java Webstart, and a new input system.
This is a demo of real-time soft shadows using 4 sources of light. The shadowing uses lightmaps but calculations and smoothing are made by GPU.
RmX3DPlugIn is an X3D importer/exporter for ATI RenderMonkey 1.5 shader authoring tool. It aims to be conformant with the X3D Ammendment 1 draft specification (X3D is the XML-savvy successor to VRML). Capabilities include the export of X3D as both worlds and prototypes for maximum reuse of shader representations, and script representations of RenderMonkey’s built-in variables. It fully supports shaders written in both the OpenGL Shading Lanugage and HLSL.
JetStreamFX is a rendering system for particles that operates in LightWave 3D Ver. 6.5-8.0. Visual effects like, volumetric smoke, clouds, flames, dust, etc. are created in high speed by using the OpenGL API for rendering. Special FX, such as shockwaves, can be generated by replacing the particles with lens flare or an object.
The new book (shipping Feb 16, 2005), Advanced Graphics Programming Using OpenGL, brings the graphics programmer beyond the basics and introduces them to advanced knowledge that is hard to obtain outside of an intensive CG work environment. The book is about graphics techniques - those that dont require esoteric hardware or custom graphics libraries - that are written in a comprehensible style and do useful things. It covers graphics that are not covered well in your old graphics textbook. But it also goes further, teaching you how to apply those techniques in real world applications, filling real world needs. Authors are from Nvidia and Microsoft.
IGN reports on the new OpenGL ES-powered gaming handset shown by LG Electronics at CES 2005 - “the worlds fastest 3D game phone”. The phone is equipped with an ATI 2300 OpenGL ES 1.0 compliant graphics acceleror running 5 times faster than its competitors and featuring PS1 quality graphics.
TGL is a C++ wrapper and extension library for the OpenGL API. It provides scene graphing and cross-platform development through “glue” libraries. “Glues” include: Qt, X11, GLUT, SDL, Allegro (with AllegGL ), with Win32 to come. The new v0.3 available for testing is a leaner version that uses StateGL++ for OpenGL states, and ImgGL++ for image loading and texturing.
A Linux version is now available of the Shader Designer, the tool designed to aid developers to write GLSL shaders. A new v1.5.9 for Windows adds changes in the mesh files and bug fixes.
particleIllusion 2.0 SE is an introductory version of the particleIllusion 2.0 engine. It offers the ability to customize and modify quality, complex particle animations with library of more than 750 preset effects (smoke, fire, explosions, water effects, sparkles, colorful artistic effects, etc.) It features OpenGL API-based hardware acceleration to provide realtime (or near realtime) previews of most effects and ultra-fast rendering of final output.
QCD is a media player, similar to WinAmp. Scope4D 6.0 is a new visualization for QCD that makes heavy use of Pixel- and Vertex Shaders, Vertex Buffer Objects, detailed meshes, high-res textures and a particle system. Now everybody can enjoy high quality OpenGL 2.0-based graphics moving to their music. 3D model artists can enhance the experience by using their own models.
The OpenGL Setup for GLSL tutorial describes the basic setup and required extensions (for pre OpenGL 2.0 developers) for including a vertex shader and a fragment shader into a a program. Sample source code is included.
