Open Source Virtual Reality Software

This repository contains source code and build scripts for implementations of the OpenXR loader, validation layers, and code samples. OpenXR is a royalty-free, open standard that provides high-performance access to Augmented Reality (AR) and Virtual Reality (VR), collectively known as XR platforms and devices. Without a cross-platform standard, VR and AR applications and engines must use each platform’s proprietary APIs. New input devices need customized driver integration. OpenXR provides cross-platform, high-performance access directly into diverse XR device runtimes across multiple platforms. OpenXR enables applications and engines, including WebXR, to run on any system that exposes the OpenXR APIs.

Bullet is real-time collision detection and multi-physics simulation for VR, games, visual effects, robotics, machine learning etc. Jvm port of Bullet, by Erwin Coumans. Take a look at the tests to see what has been ported and tested to be working. A high-end desktop GPU, such as an AMD Radeon 7970 or NVIDIA GTX 680 or better. We succesfully tested the software under Windows, Linux and Mac OSX. The software currently doesn't work on OpenCL CPU devices. It might run on a laptop GPU but performance will not likely be very good. Note that often an OpenCL drivers fails to compile a kernel. Some unit tests exist to track down the issue, but more work is required to cover all OpenCL kernels.

Understanding the anatomy of complex organs such as the human brain can be a challenge for students, so there is a definite advantage given to students who can experience the structures in a spatial way through real or virtual experiences. Since 2016, the Marquette Visualization Lab has been utilizing a dataset of 3 and 7 Tesla MRI scans from the Structural Informatics Group at University of Washington to visualize the structures of the brain in their Cave, utilizing the Unity game engine and 10 stereoscopic 3D projectors. Most MRI scans are presented as a volumetric rendering, but this dataset is unique because it was fully labelled and parcellated, allowing lab users to not only view the structures of the brain, but also virtually dissect it in a large scale, collaborative virtual reality environment. This year, in the interest of making the learning experience more mobile and accessible, the visualization was ported to the Oculus Quest.
