Interface VRRenderer

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.

  • Method Details

    • onInit

      void onInit(GraphicsDevice device)

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

      Parameters
      • device: the graphics device bound to this view

    • onEyeFrame

      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: the graphics device bound to this view

      • eye: which eye is being rendered

      • eyeCamera: the camera for this eye, already applied to the device

    • onDispose

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