Big Nerd Ranch announces the October 2008 session of OpenGL Bootcamp. This intensive 5-day training course will arm you with the knowledge to make your 2D and 3D visualizations fly! As problem sets explode in complexity, radical gains in performance have resulted from moving traditional graphics processing from the CPU to graphics hardware. If you are doing any work concerning graphics, then you must know OpenGL and this class is the fastest way to master the ideas and techniques of OpenGL programming. By taking full advantage of hardware acceleration, shaders, blending, textures and video we’ll help you get the most out of your data. Learn how OpenGL works, what functionality it does and does not provide, various optimization methods for both static and dynamic data, and much more. The course will provide libraries and frameworks for abstracting the operating system and allowing the student to focus solely on learning OpenGL.

Geeks3D has updated its OpenGL extensions section with all extensions exposed by a Radeon HD 3870 with the latest ATI Catalyst 8.7 Windows Vista 64-bit graphics drivers. Three new extensions have been added.
NVIDIA recently updated GLExpert, a component of NVPerfKit that helps OpenGL developers by identifying errors and performance issues. You will also find a link to GPU Performance Tuning with NVIDIA Performance Tools, a talk showcasing the latest suite of OpenGL GPU performance analysis tools from NVIDIA, including NVPerfKit 2 (featuring NVPerfSDK and GLExpert) and NVShaderPerf 2.
Sentinel Ave LLC, funded by the U.S. Defense Department, has posted a demo of its client software (YouTube version here) showing the viewer flying through 3D cityscapes with live videos embedded in them. The software, AVE Video Fusion, “combines Google Earth-like features with live camera videos projected on a 3D model” as noted in a video caption.It is written from scratch using C++ and OpenGL and claims to run on PCs with no custom hardware.
Faogen Fast Ambient Occlusion Generator. It uses OpenGL API to access video card GPU to accelerate computation of ambient occlusion and bent normals both as per-vertex data and in texture images. 2.0 version provide updated ambient aperture and bent normals shaders with ability to customize them through editing of GLSL code of two simple functions. Other features include improved precision on large scale models, adjustable background for AO texture images, lighting animation control and few bugfixes. Bent normals rendering instead of vertex normal uses special vector, which points in the average direction of unoccluded samples. This technique is simple and can be used even on pre-shader hardware. Ambient aperture rendering is more complicated and adds cheap dynamic shadows to view.
Sundog Software announces version 1.5 of its real-time 3D cloud and sky library, SilverLining. In addition to providing physically-based clouds of various types and an accurate simulation of the sky and tone-mapped natural lighting, version 1.5 adds rain and snow effects, 64-bit support, sample code for OpenSceneGraph integration, and significant improvements to the visual quality of clouds in the cumulus family. The new precipitation effects are based on academic research in meteorology surrounding the distribution of particle sizes and their terminal velocities, as well as visual simulation research in how to accurately render the precipitation particles, taking into account the oscillations of the particles as they fall. SilverLining will also adjust the visibility of your scene based on the precipitation type and precipitation rate you specify. Precipitation is attached to individual clouds, so as you pass underneath a rain cloud, rain will start and stop realistically.
AMD announced new ATI Catalyst™ drivers with major performance enhancements to ATI FireGL™ professional graphics cards. Availability of this enhanced 8.49.7 Linux driver represents a significant leap for Linux customers seeking improved performance of CAD and digital content creation applications that can offer up to approximately 33 percent faster OpenGL performance than the previous driver based on the SPECviewperf® 9.
NVIDA has unveiled its most powerful graphics processing units (GPU), the GeForce GTX 280 and 260. The GTX 280 has 240 multi-threaded cores and can process video 18 times faster than the latest CPUs. It has 1.4 billion transistors and is capable of nearly a teraflop. Rendering 3D images in realtime is just about the most mathematically intensive task a PC will ever engage in, and these GPUs are aimed at applications that have become increasingly visual, according to NVIDIA. According to Bryan Del Rizzo with NVIDIA, the GTX 280 has 1.4 billion transistors, is compliant with the OpenGL 2.1 standard, and is capable of 0.933 teraflops.
Catalyst 8.6 drivers released, and here are some of the new features: This release of Catalyst introduces Adaptive Anti-Aliasing Custom Filters support for OpenGL applications for the ATI Radeon HD 3000 Series, ATI Radeon HD 2000 Series of products.
