OpenGL-powered watercolor paired with tiltable and rotatable surface

In last week’s SIGGRAPH ASIA, Expresii showed a clever setup with a 28” 4K monitor mounted on a flexible arm that allows users to tilt and rotate the surface while watercolor paint flows down according to the inclination. The life-like flows and the ability to output at 12K resolution are all powered by OpenGL.

EGL Eye: OpenGL Visualization without an X Server

This post by Peter Messmer on the NVIDIA Parallel Forall blog provides the basic steps to create a (full) OpenGL context using EGL in a headless environment, with code examples. EGL context creation is particularly relevant for accelerated rendering on HPC systems or in a cloud environment, where context management via X11 is often times impractical. Applications include in situ visualization and CUDA/OpenGL interoperation.

Qt Charts 2.1.0 Release with OpenGL improved performance

The upcoming Qt 5.6.0 release includes the Qt Charts 2.1.0 add-on. This Qt Charts release contains new features and bug fixes based on customer requests.
