Method Detail

initialize

void initialize(int width,
              int height)

Constructs a new floating-point depth (z-buffer) component object with the specified width and height.

Parameters:

width - the width of the array of depth values

height - the height of the array of depth values

setDepthData

void setDepthData(float[] depthData)

Copies the specified depth data to this object.

Parameters:

depthData - array of floats containing the depth data

getDepthData

void getDepthData(float[] depthData)

Copies the depth data from this object to the specified array.

Parameters:

depthData - array of floats that will receive a copy of the depth data

retrieveDepth

final void retrieveDepth(float[] buf,
                 int wRead,
                 int hRead)
