Seac02 has released the newest version of LinceoVR, version 3.2, and adds in some new GPU acceleration features, most notably real-time raytracing support.
Version 3.2 adds real-time raytracing GPU based features, real-time texture tracking for augmented reality, an FBX importer for 3D models and animations, and a free OpenGL based viewer. The OpenGL viewer can be either a stand alone solution, or a web-based plugin controlled by JavaScript calls to see 3D interactive models online in VR and AR mode. Both LinceoVR and the viewer support HDRI lighting, real-time shadows and animations, tag and texture tracking for augmented reality, and run on all OpenGL compliant graphics cards.
The newest version is LinceoVR 3.4. For more info http://www.seac02.it/purchase/
