Video Series: glTF Model Authoring Pipeline

In this video series, Alex Wood and Ed Mackey create a glTF 3D model of a Cubesat from reference images, using Blender, VSCode, and other tools. They walk through the glTF model authoring and texturing process from scratch to a finished result, and show the result being used in STK and other apps that consume glTF models.

Khronos Group asking for feedback on removing BEGIN_RANGE / END_RANGE / RANGE_SIZE tokens from headers

The Khronos Group is asking for feedback on removing the automatically generated VK_*_BEGIN_RANGE, VK_*_END_RANGE, and VK_*_RANGE_SIZE tokens from the Vulkan headers. These tokens are currently defined for some enumerated types, but are explicitly not part of the Vulkan API. We are accepting comments on this topic in this GitHub issue. We strongly suggest any external projects using these tokens immediately migrate away from them.

Learning from Home with 3D Content

In the last several weeks learning has moved from the classroom into the home, as schools across the world have temporarily closed. The old way of learning involved reading textbooks or consuming content delivered through paper handouts. Simply Augmented is using the Smithsonian “Open Access” initiative trove of artifacts to bring 3D into your home. Simply Augmented began the process of converting the Smithsonian 3D assets into web-ready, augmented reality files and then posting them to their 3D sharing platform, Simply3D, for free. Simply3D is an easy way for anyone to host and share augmented reality assets.

NVIDIA provides OpenGL-accelerated Remote Desktop for GeForce

In these days of social distancing, game developers and content creators all over the world are working from home and asking for help using Windows Remote Desktop streaming with the OpenGL tools they use.

NVIDIA has created a special tool for GeForce GPUs to accelerate Windows Remote Desktop streaming with GeForce drivers R440 or later.

Download and run the executable (nvidiaopenglrdp.exe) from the DesignWorks website as Administrator on the remote Windows PC where your OpenGL application will run. A dialog will confirm that OpenGL acceleration is enabled for Remote Desktop and if a reboot is required.

Amazon Sumerian supports exporting your scenes to glTF

Amazon Sumerian, the AWS service that makes it easy to create and run browser-based 3D, augmented reality (AR), and virtual reality (VR) applications, now supports exporting your Sumerian scenes to glTF (GL Transmission Format), an open-source file format for 3D scenes and models that’s compatible with many other 3D editing tools and rendering engines. To learn more about the glTF file format and what is supported, please refer to our user guide.

LunarG releases OpenXR overlay extension open source implementation

LunarG announces the release of an open source implementation of the experimental XR_EXTX_overlay extension, introduced in OpenXR 1.0.8. An overlay composition layer can add a rich variety of content into other XR applications. Examples of overlay applications include desktop OS windows in-world, in-game heads up display (HUD), virtual keyboard, and chat. Work continues on the implementation with the goal of running many applications at the same time. Support for all the functions in the OpenXR core specification is planned for a later release. Please take a look at the LunarG release and refer to this document for more information.
