updateColorCameraTextureUv

public void updateColorCameraTextureUv(int rotation)

Update background texture's UV coordinates when device orientation is changed (i.e., change between landscape and portrait mode).

Parameters:

rotation -

onSurfaceChanged

public void onSurfaceChanged(javax.microedition.khronos.opengles.GL10 gl10,
                             int width,

getTextureId

public int getTextureId()

It returns the ID currently assigned to the texture where the Tango color camera contents should be rendered. NOTE: This must be called from the OpenGL render thread; it is not thread safe.

Parameters:

matrixFloats -

updateViewMatrix

public void updateViewMatrix(float[] ssTcamera)
