ogldev: PN Triangles Tessellation tutorial published

The 31st installment in a series dedicated to promoting OpenGL development on Linux. This tutorial teaches a more advanced Tessellation technique called PN Triangles. It is based on a 2001 paper by Vlachos, Peters, Boyd and Mitchell. An implementation of this technique using DX11 was recently presented by John McDonald in GDC 2011.

Unofficial OpenGL SDK, 0.4 Alpha release

The 0.4.0 release of the Unofficial OpenGL SDK. In addition to cross-platform components for OpenGL window creation, OpenGL function pointer initialization, and image loading, the 0.4.0 release adds:

  • Immediate mode-style rendering API. 100% compatible with core OpenGL 3.2+
  • Shader/Program compiling/linking wrappers. They check for errors and clean up after themselves.
  • Mouse-based camera and object controls.

All of the components use the same cross-platform build system, to make compiling and linking to those libraries easier.

PixelLight 0.9.9-R1 released, introducing Android support

Version 0.9.9 of the free open-source, cross-platform 3D application framework PixelLight has been released. The focus was on the support of mobile devices, improving Unicode support, bug fixing and enhancing the general usability of the technology. Starting with this release, there’s support for Google’s mobile operating system Android and the OpenGL ES 2.0 renderer has been improved. If supported by the GPU driver, the OpenGL ES 2.0 renderer can now be used natively under MS Windows and Linux without using an emulator. In order to make it easier to compile PixelLight, the previous simple BUILD text file has been replaced by a more sophisticated document.

jMonkeyEngine 3 SDK Beta released

After an extended delay, the jMonkeyEngine 3 SDK Beta is finally released. This will probably be our only Beta release, thanks to the new “stable branch” that will be the recommended update path from now on. The nightly builds will still be available to any daring developer who wants to keep up with the cutting edge, but we highly recommend using a separate settings folder. See the release announcement for more details. This is probably the most feature rich release in a while now that we’re focusing on going stable next. Some highlights include vastly improved Android support, improvements to the OpenGL 1 renderer, a native .blend model loader and some crucial Linux fixes. On the visual side we’ve now got steep parallax mapping, a new underwater filter and fast approximate anti-aliasing. We hope our fellow Java game developers will enjoy this release as much as we enjoyed making it a reality.

Android 4 offers new OpenMAX AL API support for low-level streaming multimedia

Google’s recently announced Android 4.0 platform, and related Ice Cream Sandwich SDK, include many new media capabilities. One very nice addition is the introduction for low-level streaming multimedia. To support this low-level streaming, the platform introduces a new native API based on the Khronos OpenMAX AL 1.0.1 API. This API is implemented on the same underlying services as the platform’s existing OpenSL ES API, so developers can make use of both APIs together if needed. Tools support for low-level streaming multimedia will be available in an upcoming release of the Android NDK. Learn more about OpenMAX AL on the Khronos Group website.
