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.
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.
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.
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.
Flexion Engine is a real-time OpenGL API-based 3D graphics rendering engine for next-generation GPUs. The new technology demo demonstrates the Dynamic Dual-Paraboloid Omnidirectional Soft Shadow Mapping. This technique enables to do omnidirectional-shadowing using only two shadow maps.
Omega Core 3D is a real-time extensible 3D game engine being used to develop the MMMORPG Caeron 3000. The code base is moving from Direct3D to OpenGL 2.0 (including the OpenGL Shading Language) in order to support cross platform portability, as well as embedded platforms.
Although the technique of alpha-blending has been around for a long time, it can be employed to produce impressive visual effects even on low-end hardware. These four demos, complete with GPL source code for Windows and Linux, present different uses of alpha-blending associated with 2D-texturing.
SPyRE (Simple Pythonic Rendering Engine) is a lightweight rendering engine for the OpenGL API. Provide pyOpenGL code to draw the model, and the SPyRE engine will display the model in an interface that provides zooming, panning and rotation of camera position using mouse and keyboard.
