The implementation is simple 3D vector scaling and addition. The
HmdMatrix34_t consists of a 3x3 rotation matrix and a 3D vector for
position.
The overlay position is only updated whenever a new overlay is changed
because we need the old overlay position in order to modify it. The
openvr call to get the position is only updated whenever you open the
menu.
A new page was created due to lack of space on the utilities page.
All images have been moved to the /img/ folder in order to fully
separate qml from images. The .qrc file allows qml to use the images by
appending the qrc:/ prefix before the abstract path to the image.
Note that the .qrc file is also check at compile time, which further
enhances the confidence the lack of errors.
Some of the images are not used in the QML, but instead directly passed
through to the OpenVR API. These have not been added to the .qrc file.
Elements work like they've always done, this just moves the commonly
used components away from the global namespace.
The qmldir file still does something, although at this point it is
unknown exactly how it's used and whether or not it could be changed to
simplify imports across the block.
Valve's official terminology are "Room Setup" and "Tracking Universe". Changed our usage of "Playspace" to "Room" for clarity with the upcoming Room-Turn feature and existing Room-Drag feature when compared to nomenclature for other tools that exits out there.
Also slight clean up in readability of movecentertab's action functions.
The QML at the moment is a giant mess. Moving pages into individual
folders and properly abstracting the sub components of the pages will
allow for much easier development and better error messages.
Additionally it will prevent polluting the global namespace. Really, all
the reasons for avoiding globally available values and using
abstractions in regular programming also come into play here.
Compare old and new pose via a relative quaternion rather than relative yaw, then calculate the resulting yaw-difference from the quaternion in one go.
