From dc2df8307f41888bab722f75fa9e73adecf86b72 Mon Sep 17 00:00:00 2001 From: Julian Eisel Date: Tue, 17 Mar 2020 20:20:55 +0100 Subject: VR: Initial Virtual Reality support - Milestone 1, Scene Inspection NOTE: While most of the milestone 1 goals are there, a few smaller features and improvements are still to be done. Big picture of this milestone: Initial, OpenXR-based virtual reality support for users and foundation for advanced use cases. Maniphest Task: https://developer.blender.org/T71347 The tasks contains more information about this milestone. To be clear: This is not a feature rich VR implementation, it's focused on the initial scene inspection use case. We intentionally focused on that, further features like controller support are part of the next milestone. - How to use? Instructions on how to use this are here: https://wiki.blender.org/wiki/User:Severin/GSoC-2019/How_to_Test These will be updated and moved to a more official place (likely the manual) soon. Currently Windows Mixed Reality and Oculus devices are usable. Valve/HTC headsets don't support the OpenXR standard yet and hence, do not work with this implementation. --------------- This is the C-side implementation of the features added for initial VR support as per milestone 1. A "VR Scene Inspection" Add-on will be committed separately, to expose the VR functionality in the UI. It also adds some further features for milestone 1, namely a landmarking system (stored view locations in the VR space) Main additions/features: * Support for rendering viewports to an HMD, with good performance. * Option to sync the VR view perspective with a fully interactive, regular 3D View (VR-Mirror). * Option to disable positional tracking. Keeps the current position (calculated based on the VR eye center pose) when enabled while a VR session is running. * Some regular viewport settings for the VR view * RNA/Python-API to query and set VR session state information. * WM-XR: Layer tying Ghost-XR to the Blender specific APIs/data * wmSurface API: drawable, non-window container (manages Ghost-OpenGL and GPU context) * DNA/RNA for management of VR session settings * `--debug-xr` and `--debug-xr-time` commandline options * Utility batch & config file for using the Oculus runtime on Windows. * Most VR data is runtime only. The exception is user settings which are saved to files (`XrSessionSettings`). * VR support can be disabled through the `WITH_XR_OPENXR` compiler flag. For architecture and code documentation, see https://wiki.blender.org/wiki/Source/Interface/XR. --------------- A few thank you's: * A huge shoutout to Ray Molenkamp for his help during the project - it would have not been that successful without him! * Sebastian Koenig and Simeon Conzendorf for testing and feedback! * The reviewers, especially Brecht Van Lommel! * Dalai Felinto for pushing and managing me to get this done ;) * The OpenXR working group for providing an open standard. I think we're the first bigger application to adopt OpenXR. Congratulations to them and ourselves :) This project started as a Google Summer of Code 2019 project - "Core Support of Virtual Reality Headsets through OpenXR" (see https://wiki.blender.org/wiki/User:Severin/GSoC-2019/).
