This article describes the implementation of soft particles in pure WebGL / OpenGL ES without any 3rd party library or engine used. This tutorial is based on a WebGL port of Android live wallpaper 3D Buddha Live Wallpaper. Source code is available on GitHub.
Founder and CTO of Third Dimension Technologies (TDT) recently gave a SMPTE webinar for members titled “Streaming Model for Field of Light Displays” (SMFoLD). The webinar focused not on the displays themselves, but the technology needed to stream real-time field of light video with synchronized sound over more-or-less ordinary network connections. TDT is working on this problem along with the Oak Ridge National Laboratory (ORNL) in a project managed by the Air Force Research Laboratory (AFRL). The title of the project is “Open Standard for Display Agnostic 3D Streaming” (DA3DS). The DA3DS project has taken the approach of transmitting not the images but the OpenGL primitive graphics calls over the network along with the data needed by the OpenGL calls. Learn how the DA3DS project is using OpenGL and how OpenXR plays a part.
The Khronos Group BOF day is today, July 31. For those folks that really wanted to catch some of the BOF Day sessions, but couldn’t make, we have it covered for you. Starting at 9AM PT, the morning livestream will start on YouTube. The afternoon sessions will be on a second afternoon livestream also on YouTube. Learn more about the Khronos Group BOF Day and all of the various sessions on our SIGGRAPH 2019 event page.
The Khronos Group announces new 3D Commerce Working Group and key updates to flagship standards WebGL, glTF, and Vulkan. In the spirit of continued commitment to the SIGGRAPH community of interactive graphics professionals, Khronos delivers a number of developments and initiatives, including:
3D Commerce Initiative Becomes Khronos Working Group; Call for Participation Announced
WebGL Releases High-Impact Extensions and Ecosystem Developments
glTF Universal Texture Extension Drafting Underway Using Binomial’s Basis Universal Texture Technology; First Prototype Support Appears in Engines
glTF Tools Ecosystem Expands, Including Universal Texture Tools and glTF Import/Export in Blender 2.80
New Vulkan Extensions Ship; Vulkan Sees Increased Usage by CAD and Professional Authoring Tools
SIGGRAPH is next week! The conference is July 28-August 1. For those going, Khronos will be hosting several Birds of a Feather sessions. For all those folks that will not be present, we will be offering live streaming of all our sessions (glTF, WebGL, OpenXR and Vulkan) on the Khronos Group YouTube Channel, and will follow up with recorded video the following week. For complete details on all the sessions, please ask your friends and co-workers to take a look at our SIGGRAPH event page! A special thanks to our Title sponsor NVIDIA, Beer Sponsor LunarG, and Demo sponsor Cesium, for making possible the Khronos Networking Reception at the end of the day.
In 2016, the Uber Visualization team released an open source version of deck.gl and luma.gl, two Khronos Group WebGL™-powered frameworks for visualizing and exploring huge geospatial data sets on maps. Since then, the technology has flourished into a full-fledged suite of over a dozen open source WebGL and GPGPU data visualization libraries and tools, known collectively as vis.gl. loaders.gl, the newest addition to the vis.gl family, adds support for loading and rendering glTF™ assets across the tech stack. Read the blog for complete details.
With the growth and adoption in mobile, web, and immersive platforms, 3D is poised to grow as a new shopping medium. Product manufacturers, retailers, marketing, and advertising platforms can use 3D to show virtual products to end-users to help them better understand a product online prior to purchasing and to help build brand loyalty after purchase. The Khronos has a track record of openness and responsiveness, with a well-proven IP Framework and multi-company governance model. The Khronos 3D Commerce Exploratory Working Group could directly leverage the work of several existing Khronos Working Groups, including: glTF, WebGL, Vulkan, and OpenXR. With enough industry support, this Exploratory Group will evolve into a Working Group to work on the development of such standards.
In a recent article of Science Advances, we introduced a WebGL library Abubu.js that makes easier to program and create high-performance simulation of cardiac dynamics and other large-scale systems like fluid flow and crystal growth. Making these kind of simulations and studies accessible to virtually anyone with a modest computer. For cardiac dynamics, this approach will allow not only scientists and students but also physicians to use physiologically accurate modeling and simulation tools that are interactive in real time, thereby making diagnostics, research, and education available to a broader audience and pushing the boundaries of cardiac science.
Khronos will be holding their Annual GDC Developer Day Sessions on March 19th in Moscone West Room 2020. The complete schedule is available online:
glTF and WebGL - 10:00am – 11:00am
OpenXR – State of the Union – 11:20am – 12:20pm
Vulkan – State of the Union - 1:20pm – 2:20pm
Making Use of New Vulkan Features – 2:40pm – 3:40pm
Bringing Fortnite to Mobile with Vulkan and OpenGL ES – 4:00pm – 5:00pm
Ubisoft’s Experience Developing with Vulkan – 5:30pm – 6:30pm
Running all day March 18-19 will be the Khronos OpenXR Table at VRDC. Finally on March 20th starting at 6:30pm, there will be the annual WebGL/WebVR Meetup to be held in Galvanize. In past years there were over 200 people attending with only standing room and people being turned away. If you want to get in, show up early. This event will be live streamed on the Silicon Valley WebGL group on Facebook.
WebGL 2.0 has emerged into a powerful technology built on the back of a very successful WebGL 1.0, and is now fully utilized across numerous professional CAD and 3D apps on the Web. Learn about WebGL 2.0’s dynamic history and how it became the most widely used web graphics API on the market.
The MIT-licensed C++11 graphics/game engine Magnum has a new version, packing WebGL-enabled and HiDPI-aware ImGui integration, tweakable constants for live coding, improved Vulkan interoperability and compilation time optimizations.
If you are attending GDC 2019, be sure to mark March 19th in your calendar. Khronos will be hosting the annual Developer Day sessions in the Moscone West, Room 2020 from 10am to 6:30PM. This year there will be six (6) sessions covering glTF, WebGL, OpenXR, Vulkan and OpenGL ES. There will also be an OpenXR table at VRDC where you can learn more about OpenXR, talk with OpenXR working group members, and learn how your company can implement or join in the development of this important industry standard. The Khronos Group is once again sponsoring the WebGL/WebVR Meetup. Last year we had over 200 RSVPs and an amazing lineup of speakers. Join Khronos member Patrick Cozzi (Cesium) and other speakers for this gathering of the Silicon Valley WebGL/WebVR meetup group.
