No Massive Data on the HoloLens without simplification? Doch! We are extending the existing instant3Dhub/naVis tech stack with a new C++/DX11 backend to enable massive CAD data on the MS HoloLens. We use a set of hybrid rendering techniques to calculate and stream visible elements to the client. The decoupled client synthesises new frames with a controlled triangle budget to maximize the end user experience. The scalable solution adapts to different network bandwidth situations and allows to render models of any size without any simplification on the HoloLens.
21.03.2017 Event instant3Dhub
Virtual Reality is one of the main key features for Industrie 4.0. This week we will present our solution at the CeBIT 2017 in Hannover. You find us at the Fraunhofer Exhibition in Hall6/B36.
More Informations under: http://www.igd.fraunhofer.de/en/node/1166
Today we will present the latest updates on our standardization efforts (glTF), including capabilities for Physically-Based Rendering (PBR) at the Khronos WebGL/WebVR/glTF Meetup on the GDC in San Fransico.
You can find the slides of the talk here.
The new 2.9 Release supports now webVR directly. A new video showcases this feature.
webVR is cool. Virtual Reality (VR) works without software deployment, just in the browser.
One major issue right now is the data size. VR needs consistently HIGH refresh rates (frames per second, FPS), but current WebGL frameworks are sensitive to the input data size. Therefore, big data leads to LOW FPS and/or excessive download times.
Our Solution: The output-sensitive instant3Dhub calculates and streams only visible parts.
We are pleased to announce the release of version 2.9.0 of the instant3Dhub. This is a significant release with a large number of bug fixes, performance improvements and three major features
The new webVis client allows the user to perform interactive single and double measurements on shape data, such as measurability (angles or minimal distances). The novel user interface facilitates complex operations through smart snapping and filtering. The data import pipeline supports formats with explicit shape data (e.g. OpenJT and X3D) or reconstructs the face and edge information automatically from triangle sets.
This solution detects connected supported Head Mounted Displays (HMD) and is made easily available through a single button in the UI. It supports reviewing scenarios with simple gestures to manipulate the data setup, all with a single unified event model.
The first public jaVis-Release builds upon our C/C++ and OpenGL backend. The object oriented API allows java application developers to build Fat Clients for large model visualization which directly access the optimized instant3Dhub data caches.
27.07.2016 instant3Dhub Release
We are pleased to announce the release of version 2.8.0 of the instant3Dhub.
The highlight of this release is support for auxiliary spatial data. This data can be a set of additional geometries, viewpoints or cutting planes. The source of this data can be PMI (Product and Manufacturing Information) and in the future BCF (BIM Collaboration Format).
In our new Aux Inspector Dialog (Aux Tree) these auxiliary attributes and data can be enabled, disabled or selected.
Changes and improvements:
There are only a few days left until the SIGGRAPH 2016 conference starts in Anaheim, CA.
This year, the instant3Dhub team is pleased to be available at the SIGGRAPH exhibition!
Our booth will be shared with the Web3D Consortium. Amongst other topics, we will present latest updates on our standardization efforts (glTF), including capabilities for Physically-Based Rendering (PBR). You can find the glTF extension proposal here.
Moreover, we will provide you with insights into ongoing developments, such as massive model rendering techniques, measuring in 3D, and more. These exciting new developments will also be presented at the WebGL Birds of a Feather Session, hosted by the Khronos group, taking place on July 27, 1:00pm – 2:30pm at the Hilton Anaheim (777 W. Convention Way), Ballroom A. So, if you are going to Anaheim, stop by at WebGL BOF, or visit us on the SIGGRAPH exhibition floor, at booth 755 (Web3D Consortium)!
08.04.2016 instant3Dhub Release
We are proud and happy to announce that, finally, instant3Dhub 2.7 has now been released! This release includes, as usually, a large number of bug-fixes and new features.

Since version 2.2.4, webVis supports a highly efficient edge enhancement as additional rendering mode. Starting from version 2.2.5, we also added a colorize effect, assigning a random color to each part. Both effects operate in screen space, using a highly efficient deferred shading method, which completely avoids a re-rendering of the 3D scene when changing materials or shading styles. Our example image shows default rendering (left), edge enhancement (middle) and edge enhancement plus random colors (right).
The Khronos Group, an open consortium of leading hardware and software companies, just announced that the glTF™ 1.0 (GL Transmission Format ) royalty-free specification for transmission and loading of 3D content has been finalized for Ratification and is immediately available for use by tools and application vendors.
With SRC, Fraunhofer IGD already provides support for a modified subset of an earlier version of glTF™. The proposed extensions KHR_binary_glTF and WEB3D_quantized_attributes have been actively developed by a team of experts, including the instant3Dhub team. This development will be bridging the gap between Khronos’ and the Web3D consortium’s standards, and it will help to ensure that instant3Dhub keeps using well-specified, standard technology. This makes instant3Dhub even safer for long-term use and helps us to ensure backwards compatibility.
