OpenGL training at Qt Developer Days

Qt Developer Days running from November 12 - 14, 2012 in Berlin Germany, will include a session on Modern OpenGL with Qt5. OpenGL is a central part of QtQuick2 in Qt 5 and also plays a key role in displaying the main content of many widget-based applications. A basic level of linear algebra will be assumed for this course (multiplying a matrix and a vector). Mathematics will be kept to a bare minimum so as not to get in the way of eye candy!

OpenGL Loader Generator

Are you tired of OpenGL loaders like GLEW that have huge headers with hundreds of extensions you never use? Plagued by “unresolved externals” and other errors when using OpenGL loading libraries? The OpenGL Loader Generator is a tool that generates a header and source file that you include directly in your project. It gives you the extensions you ask for, without a gigantic 600KB header cluttered with stuff you’ll never use. You just include the files directly in your project, just like regular header and source files. No libraries to build or link to.

OpenGL Example Collection

The purpose of thise example collection is to provide short and self contained code that showcases OpenGL api functionality/features. The examples have no dependencies on any custom framework or basecode except for “canonical” libraries such as glfw, gl3w and glm. All the examples are written against core profiles of version OpenGL version 3.3 or higher.

Libgls 1.0 released-a OpenGL stereoscopic rendering library

The libgls library allows stereoscopic rendering with OpenGL, without requiring hardware support for quad-buffered stereo. Many display modes are supported, from anaglyph glasses to various types of 3D TVs and stereoscopic displays. Advanced features include support for crosstalk reduction. Libgls is available under the MIT/X11 license.

Voreen Version 4.1 Released

Version 4.1 of the open-source, cross-platform volume visualization tool Voreen is now available for download. This version adds processors performing volume rendering with global illumination, includes pre-integrated transfer-functions and improves multimodal slice rendering. ATI/AMD compatibility with OpenCL has also been improved. Robustness and speed of the DICOM reader has been increased, camera handling for transformed datasets has been fixed and mutual information co-registration using ITK has been extended.
