struct GxrContextClass

struct GxrContextClass {
  GObjectClass parent;
};

Members

GObjectClass parent;

The parent class

  

enum GxrEye

Type of Gxr viewport.

Members

GXR_EYE_LEFT

Left eye.

  

GXR_EYE_RIGHT

Right eye.

  

enum GxrStateChange

Members

GXR_STATE_FRAMECYCLE_START

Ready to call gxr_context_begin_frame / gxr_context_end_frame.

  

GXR_STATE_FRAMECYCLE_STOP

Not ready to call gxr_context_begin_frame / gxr_context_end_frame.

  

GXR_STATE_RENDERING_START

The frame content will be shown in XR.

  

GXR_STATE_RENDERING_STOP

The frame content will not be visible, expensive rendering work can be skipped, but gxr_context_begin_frame / gxr_context_end_frame should be called.

  

GXR_STATE_SHUTDOWN

XR Runtime is shutting down.
