OpenVR SDK
---
OpenVR is an API and runtime that allows access to VR hardware from multiple
vendors without requiring that applications have specific knowledge of the
hardware they are targeting. This repository is an SDK that contains the API
and samples. The runtime is under SteamVR in Tools on Steam.
### Documentation
Documentation for the API is available on the [Github Wiki](https://github.com/ValveSoftware/openvr/wiki/API-Documentation)
More information on OpenVR and SteamVR can be found on http://steamvr.com

This directory contains files from the OpenVR SDK, version 1.0.6.
This SDK contains the OpenVR API interface headers and functions to load the
OpenVR runtime libraries which actually implement the functionality. The
loading functions parse a .json file in a pre-defined location on the
end-user's machine to get details used to bind the correct runtime library.
The OpenVR implementation ensures forward and backwards compatibility as of
the current version.
Updated versions of the OpenVR SDK are available on Github:
https://github.com/ValveSoftware/openvr
We only use some files from the SDK:
- We strip out files such as C# headers, plain C API versions, and files
needed only when implementing OpenVR drivers.
- CMake related files, such as CMakeLists.txt are skipped as we use moz.build
files to configure the library.
- The "src/jsoncpp.cpp" file and the "src/json" directory can be skipped. OpenVR
uses the jsoncpp library, which we have already imported elsewhere.
Steps to update the library:
- Copy "README.md" from the root of the openvr repo to the "gfx/vr/openvr" directory.
- Copy "headers/openvr.h" to "gfx/vr/openvr/headers" directory. The other files
in this directory can be ignored.
- The rest of the files in the "src" directory and the "src/vrcommon" are copied
to the "gfx/vr/openvr/src" directory.
- Update "gfx/vr/openvr/moz.build" when files are added or removed.
- Update the "strtools_public.h" and "strtools_public.cpp" files, commenting out
the "Uint64ToString" function. This function name conflicts with another used
in Gecko. Fortunately, the OpenVR SDK does not use this function either.
- Replace the #define VR_INTERFACE in openvr.h to avoid extern'ing the functions.
Unlike the usual OpenVR API builds, we are not building a separate dll.
- Update this README.mozilla file with the new OpenVR SDK version and any
additional steps needed for newer versions.
- Ensure that any changes made within the OpenVR files have comments including
the string "Mozilla" and reference this file for easy identification.

This is the source code for the OpenVR API client binding library which connects
OpenVR applications to the SteamVR runtime, taking into account the version
of the OpenVR interface they were compiled against.
The client binding library - openvr_api.dll on Windows, openvr_api.so on
Linux, and openvr_api.dylib on macOS - knows how to find and read the
SteamVR runtime installation information which allows it to find and
dynamically connect to the installed runtime. In combination with the
interface version identifiers from /include/openvr.h which are baked
into applications at the time they are built, the OpenVR API client
binding library captures and conveys to the SteamVR runtime the version
of the OpenVR API interface behavior that the application expects.
Applications carry with them a private/local copy of the client binding
library when they ship, and they should install it locally to their
application. Applications should not install the client binding library
globally or attempt to link to a globally installed client binding library.
Doing so negates at least part of the ability for the client binding library
to accurately reflect the version of the OpenVR API that the application
was built against, and so hinders compatibility support in the face of
API changes.
Most applications should simply link to and redistribute with their application
the pre-built client binding library found in the /bin directory of this
repository. Some small number of applications which have specific requirements
around redistributing only binaries they build themselves should build
the client library from this source and either statically link it into
their application or redistribute the binary they build.
This is a cmake project, to build it use the version of cmake appropriate
for your platform. For example, to build on a POSIX system simply perform
cd src; mkdir _build; cd _build; cmake ..; make
and you will end up with the static library /src/_build/libopenvr_api.a
