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.

Jan 14, 2005 | Categories: Processors | Comments

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 v0.3 (alpha) graphics library based on the OpenGL API is smaller and faster

Jan 14, 2005 | Categories: Developers | Comments

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.

Linux version of the Shader Designer for OpenGL Shading Lanugage

Jan 13, 2005 | Categories: Applications | Comments

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.

Scope4D 6.0 QCD media player visualization plug-in uses OpenGL 2.0

Jan 10, 2005 | Categories: Applications | Comments

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.

Jan 10, 2005 | Categories: Developers | Comments

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.

VREng V6.3.3 OpenGL API-based VR engine adds XML format and object persistence

Jan 10, 2005 | Categories: Applications | Comments

VREng is an open source C++ and OpenGL API-based interactive distributed 3D application for navigating in and interacting with virtual environments over the Internet through their avatars, chat, audio/video channels, shared white-boards and document publishing.  The new v6.x uses XML to describe VR environments, supports object persistence, new file types, and built in image capture.  It run on Unix platforms (Linux, *Bsd, MacOSX, Solaris)using X11.

Solaris drivers for Matrox Parhelia include OpenGL 1.4 support

Jan 08, 2005 | Categories: Processors | Comments

Xi Graphics released high-performance, commercial-off-the-shelf Solaris (on Intel) OpenGL 1.4 graphics drivers for Matrox’s Parhelia, Millennium-P Series, and QID graphics cards on Solaris (on Intel). Using advanced VLIW and SIMD optimization techniques along with combined instruction scheduling, register allocation and resource mapping, the compiler translates ARB_vertex_program type programs into efficient microcode.

Real-Time Fluid Simulation demo using the OpenGL API

Jan 07, 2005 | Categories: Applications | Comments

Rendering realistic moving water is one of the key techniques that immerse the viewers into interactive graphics world including computer games. This demos shows real-time particle-based fluid simulation using Smoothed Particle Hydrodynamics. OpenGL ARB fragment and vertex programs are used for rendering the realistic fluid surface. The demo enables the user to interact with fluids.

The OpenGL Extension Wrangler Library (GLEW) is a cross-platform C/C++ OpenGL API extension loading library that provides efficient run-time mechanisms for determining which OpenGL extensions are supported on the target platform. Core and extension functionality is exposed in a single header file.  The latest v1.3.0 release adds support for core OpenGL 2.0 functionality, custom code generation for lean and mean applications, and a new function for efficient string-based extension queries. GLEW is available for Windows, Linux, Mac OS X, FreeBSD, Irix, and Solaris.
