OpenCTM v0.7 compressed 3D mesh file format and SDK

Aug 31, 2009 | Categories: Developers | Comments

The first beta of the OpenCTM file format and SDK for compressed 3D triangle meshes has been released, and is available for download for all major platforms. OpenCTM is ideal when you want lossless compression of your 3D models, and an easy way to load them into your application. The OpenCTM API allows you to load a file in less than ten lines of code, and the software library is very light weight and easy to use from most programming languages. The API is similar to the OpenGL API, and directly compatible with the OpenGL rendering pipeline. The mesh format is fully extensible, and allows you to define custom vertex attributes that can be used in GLSL, for instance. And the best of all: OpenCTM is completely open and free to use by any application, since it is released under the zlib/libpng license.

Australian Defence Force uses OpenGL to power its latest flight simulator

Aug 31, 2009 | Categories: General | Applications | Comments

The Australian Defence Force (ADF) is going open source. Using Suse Linux-based clusters of Opteron servers and OpenGL to power the graphics. Defence spokesman claim the simulator boots in roughly 30 seconds on a cluster of 4-core Opteron 2218 servers using NVIDIA Quadro FX 5600G graphics cards. The avionics and aerodynamics simulations run on a number of 8-core Opteron systems. The visuals software was written in OpenGL using commercial and open-source scene graph engines and makes “heavy use of OpenGL Shader Language programs” for creating effects such as clouds, smoke and vegetation.

Visualization Library 2009.08 stable based on OpenGL released

Aug 28, 2009 | Categories: Developers | Comments

Visualization Library is a C++ middleware for high-performance 2D and 3D graphics applications based on the industry standard OpenGL 2.1, designed to develop portable applications for the Windows, Linux and Mac OS X operating systems. Visualization Library has been designed to be a generic, fine-grained platform, upon which highly-specialized 3D graphics applications can be effectively developed. Visualization Library is a toolkit that provides you with the power and flexibility of OpenGL within a light and user friendly C++ object oriented framework.

Tutorial on deforming 3D geometry using RBFs using OpenGL

Aug 27, 2009 | Categories: Developers | Comments

We present a method for deforming three dimensional geometry using a technique relying on radial basis functions (RBFs). The tutorial will give a short introduction to the linear algebra involved. However accompanying source code contains a working implementation of the technique which may be used as a black box.

NVIDIA releases updated OpenGL 3.2 beta drivers

Aug 25, 2009 | Categories: General | Developers | Comments

NVIDIA released updated OpenGL 3.2 beta drivers today for both Linux and Windows. These drivers implement the full OpenGL 3.2 and GLSL 1.50 feature set, as well as fix several bugs. You can download these drivers here.

VMD 1.8.7 adds rendering features, GPU computing w/ CUDA

Aug 25, 2009 | Categories: Applications | Comments

VMD provides new capabilities for the display of molecular orbitals arising in quantum chemistry simulations, graphical representations for illustration of carbohydrates and other multi-branched structures, high dynamic range images, and eerily three dimensional renderings using ambient occlusion lighting. The new release expands the use of OpenGL shading language, adding edge-outline material properties. One of the key advancements included in VMD 1.8.7 is support for GPU accelerated visualization and analysis, based on CUDA. Typical GPU acceleration factors for the algorithms in VMD are: electrostatics 22x to 44x, implicit ligand sampling 20x to 30x, molecular orbital calculation 100x to 120x.

Stereoscopic rendering - new python OpenGL example code

Aug 13, 2009 | Categories: Developers | Applications | Comments

Stereoscopic camera geometry can be hard to correctly implement to avoid eye strain and perceived depth distortions. To add to the existing information on stereoscopic displays and image creation on the binocularity web site we have produced new examples and descriptions of stereoscopic rendering with OpenGL and GLUT in python. Two examples are available - one using toed-in camera geometry, demonstrating the drawbacks of the approach. And one using the preferred parallel camera geometry. Full instructions on installing and running the examples are provided. The binocularity web pages are the outreach site for the Durham Visualization Laboratory’s long standing work on the human factors and applications of 3D displays. The python code examples and lots more information on using stereoscopic 3D displays are freely available at www.binocularity.org
