Qt3D 2.0 The FrameGraph

KDAB are rewriting the Qt3D module of Qt 5 to provide an easy but flexible API for easily getting 3D content into your Qt applications using either C++ or QML. After reading this 4th article in the series, you will understand the difference between the Scenegraph and the Framegraph and see their respective uses. For the more adventurous amongst you, pick up a pre-release version of Qt3D and start experimenting to see what the Framegraph can do for you.

GDC 2015: Khronos Group sessions and the Next Generation of Graphics and Compute API

The Khronos Group will be holding a number of sessions off-site during GDC week. There will be two sessions dedicated to discussing the Next Generation of Graphics and Compute API, as well as an OpenCL and WebGL meetup. These sessions will be taking place at SF Green Space (EEFG) just a few minutes walking distance from the Moscone center on Wednesday and Thursday. Registration is highly advised for the off-site sessions as space is limited and a good crowd is expected. Complete details are available on the Khronos GDC 2015 event page.

Substance 3D OpenGL rendering software is now free to use

Substance 3D is a windows based application for rendering 3D photo realistic art using OpenGL. There are five OpenGL realtime visualization modes: Point clouds + skeleton, Soft (velvet-like), Dispersive (chromatic dispersion), Plaster (Ambient occlusion) and Specular (Global illumination). For optimal efficiency, Substance 3D uses multiple CPU-cores (if available) for GUI management, Shapes modeling calculations and Photorealistic rendering. As well, Substance 3D uses High Dynamic Range images (probes) as realtime lighting environment and can import up to 32 probes in its library.
