Google VR NDK Reference

C and C++ reference pages for the Google VR NDK.

Modules
Controller API	This is the Controller C API, which allows access to a VR controller.
GVR Beta APIs	These are Beta APIs that are likely to change between releases.
Gesture C API	The Gesture C API allows clients to recognize touchpad and button gestures from a controller.
Google VR Base C API	This is the Google VR C API.
Google VR Types	Various types used in the Google VR NDK.
Head Mounted Display	Functions for managing viewer information.
Head tracking	Functions for managing head tracking.
Spatial Audio API	This is the GVR Audio C API, a spatial audio rendering engine, optimized for mobile VR.
Surround Renderer API	This is the GVR Binaural Surround Renderer C API which reads in PCM buffers of surround sound as well as ambisonic soundfield content to render binaural stereo.
Swap chains and frames	Functions to create a swap chain, manipulate it and submit frames for lens distortion and presentation on the screen.
Viewports and viewport lists	Objects to define the mapping between the application's rendering output and the user's field of view.

Classes
gvr::AudioApi	This is a convenience C++ wrapper for the Audio C API.
gvr::AudioSurroundApi	This is a convenience C++ wrapper for the Audio Surround C API.
gvr::BufferSpec	Convenience C++ wrapper for gvr_buffer_spec, an opaque pixel buffer specification.
gvr::BufferViewport	Convenience C++ wrapper for the opaque gvr_buffer_viewport type.
gvr::BufferViewportList	Convenience C++ wrapper for the opaque gvr_buffer_viewport_list type.
gvr::ControllerApi	This is a convenience C++ wrapper for the Controller C API.
gvr::ControllerState	Convenience C++ wrapper for the opaque gvr_controller_state type.
gvr::Frame	Convenience C++ wrapper for gvr_frame, which represents a single frame acquired for rendering from the swap chain.
gvr::GestureApi	This is a convenience C++ wrapper for the Gesture C API.
gvr::GvrApi	This is a convenience C++ wrapper for the Google VR C API.
gvr::Properties	Convenience C++ wrapper for gvr_properties.
gvr::SwapChain	Convenience C++ wrapper for gvr_swap_chain, which represents a queue of frames.
gvr::UserPrefs	Convenience C++ wrapper for gvr_user_prefs.
gvr::WrapperBase	Base class for all C++ wrapper objects.

Structs
gvr_clock_time_point	A monotonic system time representation.
gvr_event	Container for various GVR-events to which the client can optionally respond.
gvr_mat4f	A floating point 4x4 matrix stored in row-major form.
gvr_quatf	A floating point quaternion, in JPL format.
gvr_recenter_event_data	Event data associated with a GVR_EVENT_RECENTER event, which indicates head tracking recentering.
gvr_rectf	A floating point 2D rect.
gvr_recti	An integral 2D rect. Used for window bounds in pixels.
