Class ThermalTrigger

  +--flightclub.client.ThermalTrigger

All Implemented Interfaces:

CameraSubject, ClockObserver

public class ThermalTrigger

extends java.lang.Object

implements ClockObserver, CameraSubject

This class implements a thermal trigger. Every cycle the trigger releases a bubble of warm air that floats up to produce a cloud. Well, that is the impression we hopefully evoke. The trigger model contains lots of dubious assumptions and gross simplifacations. Good ! We add a veneer of noise to the otherwise clockwork like behaviour of the trigger without departing from the deterministic model. TODO: destroyMe

Constructor Summary

ThermalTrigger(ModelViewer modelViewer, int x, int y, int cloudSize, float t0)
Creates a trigger at (x, y).

Method Summary

static float	getCycle(int size) Returns the cycle length for a given cloud size.
float[]	getEye()
float[]	getFocus()
void	tick(float t, float dt) Make a cloud every cycle period of time.

Constructor Detail

ThermalTrigger

public ThermalTrigger(ModelViewer modelViewer,
                      int x,
                      int y,
                      int cloudSize,
                      float t0)

Creates a trigger at (x, y). t is the current time and t0 is the time that the trigger creates its first bubble. We may have t > t0. In this case we need to calculate the number of clouds that this trigger has already produced. TODO: look back in time to see what clouds this trigger has already produced which still exist and produce them !

Method Detail

tick

public void tick(float t,
                 float dt)

Make a cloud every cycle period of time.

Specified by:

tick in interface ClockObserver

getCycle

public static float getCycle(int size)

Returns the cycle length for a given cloud size.

getFocus

public float[] getFocus()

Specified by:

getFocus in interface CameraSubject

getEye

public float[] getEye()

Specified by:

getEye in interface CameraSubject
