VMD v1.8.3 molecular visualization tool adds support for OpenGL Shading Language, new representation
VMD is an open source molecular visualization program (Windows, Mac OS X , & Unix) for displaying, animating, and analyzing large biomolecular systems using 3D graphics and built-in scripting. The new v1.8.3 adds initial support for OpenGL Shading Language for high-quality fragment-rate lighting of space-filling molecular representations, and atomic Van der Waals spheres rendered via ray tracing within the fragment shader. It also adds support for a new volumetric file formats, 3D texturing of molecular geometry by potential maps, and density maps. A new caching system accelerates interactive rotation of static molecular structures on tiled display walls and other network-connected display systems with limited bandwidth and nomrally high latency.
The new LightWorks 7.5 renderer provides a single API for device-independent access to hardware rendering on cards supporting the OpenGL Shading Language and Cg. It also adds improved global illumination for rendering, new architectural and industrial shaders, and cross-platform plug-in shaders.
The GL Mathematics (GLM) mathematics library provides mathematics tools based on OpenGL Shading Language specification. GLM support OpenGL Shading Language vectors and matrix types and almost all OpenGL Shading Language functions are available. The project is platform independentand has been tested under Visual C++ 7.1, MinGW and GCC.
JavaWorld features an excerpt from the new book “Learning Java Bindings for OpenGL (JOGL”. The article explains how to get JOGL up and running to access the power of the OpenGL API from Java. It also walks the reader through a couple of starter apps. The book explains in detail the basics of the OpenGL API from the Java programmer’s perspective and goes as far as to describe drawing geometric primitives, first person 3D movement and even basic textures. It is written as an introduction for Java programmers that are new to the OpenGL API.
BuGLe is an open source tool for OpenGL API code debugging, implemented as a wrapper library that sits between your program and OpenGL. It allows a developer to view OpenGL state at any time. The latest release includes nearly all of the state listed in the specification. This includes the ability to view OpenGL Shading Language shader source, info logs, values of uniforms and generic attribute bindings. Both GL_ARB_shader_objects objects and core OpenGL 2.0 shaders and programs are supported.
sdljava is a Java binding to the SDL API with support for audio, keyboard, mouse, joystick, 2D framebuffer and 3D hardware. This new v0.9.1 release removes the dependency on JDK 1.5 and adds the OpenGL binding via GLEW and a binding to FTGL.
ATI Linux drivers for FireGL V5000 OpenGL API workstation accelerator
The ATI FireGL V5000 OpenGL API accelerator gives users hi-end features and performance for the mid-range workstation market. Features include dual DVI connectors, dual link support, stereo 3D with quad-buffered support, eight pixel pipelines, six geometry engines, increased sub-pixel precision and 128MB of GDDR3 memory. The FireGL V5000 is certified to support 3ds max, VIZ 2005, Catia, Maya, Softimage|XSI, and SolidWorks. The new unified FireGL drivers now include Linux support for the V5000.
FTV v0.1 generates and visualizes terrain using fractal algorithms. It uses the OpenGL API and includes many advanced features like: multi texturing, shadows, clouds, fog, LOD, lens flares, and shaders. The GLEW extension loadinng library is required.
The Sony PlayStation 3 (PS3) is the next generation PlayStation game console with a release date as early as the end of 2005. This article reviews the technical specs that are expected to be part of the system (CPU, GPU, RAM) as well as the use of open standards APIs including OpenGL ES.
Xj3d vM10 OpenGL API-accelerated X3D browser/toolkit enhances rendering speed and uses OpenGL Shadin
Xj3D is an open source toolkit for X3D (the XML and network-savvy successor to VRML), completely written in Java and using the OpenGL API for hardware acceleration. The new Xj3D M10 features installers for Windows, Linux and Mac OS X. It now uses JOGL Java bindings for OpenGL which give it a 2X speed increase. The new H-Anim component support uses a hardware path and OpenGL Shading Language shaders for 2-3X speed improvement on Nvidia GeForce cards. M10 also adds support for several key X3D components including: CADGeometry, DIS (distributed interactive simulation), and GeoSpatial. Custom extensions include: Rigid Body Physics, Particle Systems, Clipping planes, Picking Utilities, Abstract Device IO.
This basic Vertex Buffer Objects demo loads up an image and creates a landscape from it based on the pixels intensity. Simple but useful for learning.
Texture bombing is a technique that adds richness to a surface by randomly distributing small detail images onto it in texture space. The demo uses the OpenGL Shading Language and requires a GeForce 6x00 card to run.
KToon is an open source 2D animation toolkit for cartoon production based on traditional animation. It uses the OpenGL API and QT. This first release includes two modules: Ilustration and Animation. Also supports onion-skin and motion tweening.
This is a set of 12 demos with source for writing Shaders on programmable GPUs. Most require NVIDIA FX5200 or better, although some may run on older cards. The demos were written on Linux, but all based on GLUT so they should run on Windows or other platforms.
The OpenGL Easy Extension library (GLee) makes life easier for OpenGL developers by automatically linking OpenGL extensions and core functions at initialization time. The new v5.02 for Windows and Linux adds support for the EXT_framebuffer_object. It supports OpenGL 2.0 and 332 extensions (17 new since 4.0), as well as offering support for experimental extensions.
