Leadwerks Offers Torque Developer Discount
Nov 15, 2010
In response to last yesterday’s announcement by InstantAction, Leadwerks is offering a 50% discount for Torque developers who migrate to Leadwerks Engine. “It’s sad to see such a long-established brand come to an end,” said Josh Klint, CEO of Leadwerks. “They’ve always provided a unique pathway for indie game developers, and we have a long history of supporting Torque developers with our level editing tools. In addition to the Torque developer discount, we’re also in discussions with pureLIGHT Technologies to see how developers can migrate their license to pureLIGHT for Leadwerks. InstantAction may be gone, but indie game development must continue on.” To claim your discount, see the order form here.

New GL3W release with support for dynamic linking
Nov 15, 2010
gl3w offers an easy way to get your hands on the functionality offered by OpenGL 3/4 core profile specification. It consists of a simple Python 2.6 script that downloads the Khronos supported gl3.h header and generates gl3w.h and gl3w.c from it. Those files can then be added and linked (statically or dynamically) into your project.

ClanLib 2.2.5 Released
Nov 12, 2010
ClanLib is a cross platform C++ toolkit library based around OpenGL. It’s primary focus is on games (free or commerical thanks to a BSD style license). Image, Sprite and Font drawing are optimised to give high frame rates by drawing in batches, reducing OpenGL state changes. If OpenGL v2.0 or above is not available, the library seamlessly provides OpenGL v1.3 or a high performance software renderer. Supports multiple windows with a full GUI framework for use in 2D or 3D applications. This latest version contains new examples demonstrating the ease of creating custom shaders. In addition, a HDR test has been updated to demonstrate using OpenGL floating point textures.

Hardware Video Decode and OpenGL Video Texturing for Linux
Nov 09, 2010
VDPAU (Video Decode and Presentation API for Unix) allows Linux systems to offload portions of video decode to the GPU. The resulting video can be post-processed with OpenGL, CUDA, or both. Watch Stephen Warren from NVIDIA explain VDPAU and demonstrate OpenGL texturing of hardware-decoded video frames. Slides (PDF) are also available.

GPU Pro 3: Call for Authors
Nov 09, 2010
After the success of the first seven entries to the ShaderX book series, of GPU Pro and the soon to be released GPU Pro 2, we are looking for authors for GPU Pro 3. The upcoming book will cover advanced rendering techniques that run on the DirectX or OpenGL run-times, or any other run-time with any language available. It will include topics on: Geometry Manipulation; Rendering Techniques; Handheld Devices Programming; Effects in Image Space; Shadows; 3D Engine Design; Graphics Related Tools; Environmental Effects and a dedicated section on General Purpose GPU Programming that will cover CUDA, DirectCompute and OpenCL examples. Proposals are due by March 17th, 2011. Contact details, an example proposal, writing guidelines and a FAQ can be downloaded from gpupro3.blogspot.com.

Texture and buffer access performance with OpenGL
Nov 03, 2010
Currently there are several ways to feed data to the GPU regardless of which API we use and type of application we develop. In the case of OpenGL we have uniform buffers, texture buffers, texture images, etc. The same is true for OpenCL and other compute APIs, which provide even more fine-grained memory management, taking advantage of the local data store (LDS) available on today’s hardware. This article presents memory access performance characteristics of AMD’s Evergreen-class GPUs, with a focus on what this all means from an OpenGL point of view. While most of the data is about the HD5870, the general principles and relative performance characteristics are valid for other GPUs.

3D Anatomy software uses OpenGL for multiple model viewing windows
Oct 28, 2010
3D Muscles Teacher, a training application for medical students and physio-therapists can display views of the model in an arbitrary number of interactive viewing windows. The application uses OpenGL for auto-colorization and display of auto-hiding muscle name labels. The offline program has internet bindings to retrieve further public information about the muscular system. A demo version can be downloaded from our website.
