MeVisLab 2.3 adds advanced rendering features based on GLSL
Jul 23, 2012
MeVisLab 2.3 adds several new visualization features based on OpenGL and GLSL: - deep shadow mapping (DSM) and local ambient occlusion (LAO) for Volume Rendering - screen-space ambient occlusion (SSAO, HBAO) - percentage closer soft shadows (PCSS) - mixing Volume Rendering and geometry with consistent shading - rendering of 3D geometry intersections on 2D slices (using the geometry shader) - the open source Open Inventor version provided with MeVisLab now supports fast VA/VBO rendering MeVisLab is a cross-platform image processing and visualization application focused on medical imaging. MeVisLab 2.3 is available as free download for non-commercial use for Windows/Linux/MacOS X, including 64bit versions.

Invitation to attend the OpenGL BOF at SIGGRAPH 2012
Jul 20, 2012
You are cordially invited to attend the OpenGL BOF on Wednesday 6-7pm in the Gold Ballroom in the JW Marriott hotel to celebrate 20 years of OpenGL with us. You’ll learn what is new and upcoming with the OpenGL API. We will also have two special guest speakers. Rich Geldreich from Valve will talk about their awesome project “Steam’d Penguins” that brings Steam and OpenGL games to Linux. Rich will be speaking about their challenges and successes porting Left 4 Dead 2 to OpenGL on Linux. Kurt Akeley, co-founder of SGI and of the OpenGL API will give his perspective on 20 years of OpenGL development. Right after the BOF we’ll open the doors for the OpenGL 20th anniversary party, with free drinks and various prizes to win. For more information, visit our Siggraph webpage.

Voreen (Volume Rendering Engine) Version 4.0 Released
Jun 22, 2012
Voreen 4.0 integrates ITK for a wide range of ready-to-use filtering and segmentation algorithms. Runtime editing of OpenCL kernels for volume and image processing has been added and GLSL shaders of most processors can now be modified using a shader property. In addition, the multi-view capabilities have been extended. The volume classes have been re-designed for improved meta-data support, including handling of spacing, transformations and units. A new, vastly improved DICOM reader based on GDCM library has been implemented that supports JPEG 2000 compressed DICOMs, direct reading from PACS servers and is configurable using XML. Registration in Voreen is now also a lot easier for the developer and user. On the technical side, we have switched to the CMake build system resulting in a much smoother build process, especially on Windows. Furthermore, a pre-compiled 64-bit version of Voreen for Windows is provided.

Volume rendering plugins for the PixelLight engine
Jun 21, 2012
As part of a master thesis, volume rendering plugins using GPU shader based volume raycasting were written for the free open-source, cross-platform 3D application framework PixelLight. The renderer is using OpenGL and GLSL shaders, which are dynamically composed during runtime. Beside a demo, videos and screenshots, the source codes are available as well.
