getStartTime

public long getStartTime()

Get the timestamp when the path tracing started.

Returns:

the start time in milliseconds

setSize

public void setSize(int width,
 int height)

Set the size of the canvas. Destroys the previous image and creates a new one.

Parameters:

width - the width

height - the height

getImage

Set the camera to be used for rendering the scene.

Parameters:

camera - the camera to use for path tracing

isRunning

public boolean isRunning()

Check if the path tracer is currently processing.

Returns:

true if the worker is active and not done or cancelled, false otherwise
