star3map iPhone 3Gs app is Open Source

This star and planet charting iPhone 3Gs app uses your current global position, heading, and accelerometer data to draw a current picture of the stars and planets around you. A small portion of the code is GPL licensed, but the bulk is BSD-style license or less restrictive. The app and source code make a great learning tool.

The Open Toolkit library 1.0 beta-3 released

The Open Toolkit library is an open-source wrapper that allows .Net/Mono applications to use OpenGL¸ OpenAL and OpenCL. This release improves stability under multi-threading scenarios, introduces a new multithreading sample, improves inline (intellisense) and hardcopy (PDF) documentation and fixes a large number of secondary issues. The Open Toolkit can be used on Windows, Linux, Mac OS X, Solaris and *BSD and is especially suitable to rapid development of games, GUIs, virtual reality and scientific visualizations.

Khronos Unleashes Cutting-Edge, Cross-Platform Graphics Acceleration with OpenGL 4.0

The Khronos Group announced the release of the OpenGL® 4.0 specification. This is a significant update to the most widely adopted 2D and 3D graphics API, and includes the GLSL 4.00 update to the OpenGL Shading language allowing developers to access the latest generation of GPU acceleration. OpenGL 4.0 further improves the close interoperability with OpenCL™ for accelerating computationally intensive visual applications. Among the new features: two new shader stages that enable the GPU to offload geometry tessellation from the CPU; per-sample fragment shaders and programmable fragment shader input positions; drawing of data generated by OpenGL, or external APIs such as OpenCL, without CPU intervention; shader subroutines for significantly increased programming flexibility; 64-bit double precision floating point shader operations and inputs/outputs for increased rendering accuracy and quality. Khronos has also released an OpenGL 3.3 specification, together with a set of ARB extensions, to enable as much OpenGL 4.0 functionality as possible on previous generation GPU hardware.
