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.
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.
