public interface VRRenderer

Application supplied callback that draws the scene for a VRView. Like com.codename1.gpu.Renderer, every method runs on the platform render thread that owns the GPU context - never touch Codename One UI components from these callbacks.

The view clears the frame, sets the per-eye viewport and camera, then invokes #onEyeFrame(GraphicsDevice, VREye, Camera) once per eye (twice per frame in stereo, once with VREye#CENTER in mono). Draw the same scene for every eye; the camera differences produce the stereo effect.

Methods

`public abstract void onInit(GraphicsDevice device)`	Invoked once after the GPU context is created.
`public abstract void onEyeFrame(GraphicsDevice device, VREye eye, Camera eyeCamera)`	Invoked once per eye per frame to render the scene.
`public abstract void onDispose(GraphicsDevice device)`	Invoked when the GPU context is being torn down.

Method details

onInit

public abstract void onInit(GraphicsDevice device)

Invoked once after the GPU context is created. Allocate buffers, textures and materials here.

Parameters

device GraphicsDevice: the graphics device bound to this view

onEyeFrame

public abstract void onEyeFrame(GraphicsDevice device, VREye eye, Camera eyeCamera)

Invoked once per eye per frame to render the scene. The viewport and camera are already configured for this eye.

Parameters

device GraphicsDevice: the graphics device bound to this view
eye VREye: which eye is being rendered
eyeCamera Camera: the camera for this eye, already applied to the device

onDispose

public abstract void onDispose(GraphicsDevice device)

Invoked when the GPU context is being torn down. Release resources not owned by the device. May be invoked with a null device when the context was lost.

Parameters

device GraphicsDevice: the graphics device, or null if the context was lost
