Method Summary

Modifier and Type	Method	Description
protected javax.vecmath.Vector3f	getCenter()	Calculates the center of the "view cuboid" in light space first, and then converts this to world space using the inverse light's view matrix.
protected float	getHeight()
protected float	getLength()
javax.vecmath.Vector3f	getLightDirection()	Read/Writeable vector of the light/shadow direction (most likely inverted lightposition)
protected float	getWidth()
void	onInit()	This method gets called once in the GameObject life cycle.
void	onRender()	In this method the GameObject gets rendered onto the screen (if it has an graphical representation).
void	onUpdate()	Updates the bounds of the shadow box based on the light direction and the camera's view frustum, to make sure that the box covers the smallest area possible while still ensuring that everything inside the camera's view (within a certain range) will cast shadows.
void	setViewCamera(Camera viewCamera)	Set camera to align shadow map to view frustuum

public ShadowBox()

Method Detail

setViewCamera

public void setViewCamera(Camera viewCamera)

Set camera to align shadow map to view frustuum

Parameters:

viewCamera - Camera to align to

getLightDirection

public javax.vecmath.Vector3f getLightDirection()

Read/Writeable vector of the light/shadow direction (most likely inverted lightposition)

Returns:

Read/Writeable vector of the light/shadow direction

onInit

public void onInit()

Description copied from class: GameObject

This method gets called once in the GameObject life cycle. Even if the GameObject gets removed and readded, this method dont gets called again. Its like an additional constructor, except that its not gets called when the GameObject gets created, but when its first has to action.

Overrides:

onInit in class GameObject

onUpdate

public void onUpdate()

Updates the bounds of the shadow box based on the light direction and the camera's view frustum, to make sure that the box covers the smallest area possible while still ensuring that everything inside the camera's view (within a certain range) will cast shadows.

Overrides:

onUpdate in class GameObject

getCenter

protected javax.vecmath.Vector3f getCenter()

Calculates the center of the "view cuboid" in light space first, and then converts this to world space using the inverse light's view matrix.

Returns:

The center of the "view cuboid" in world space.

getWidth

protected float getWidth()

Returns:

The width of the "view cuboid" (orthographic projection area).

getHeight

protected float getHeight()

Returns:

The height of the "view cuboid" (orthographic projection area).

getLength

protected float getLength()

Returns:

The length of the "view cuboid" (orthographic projection area).

onRender

public void onRender()

Description copied from class: GameObject

In this method the GameObject gets rendered onto the screen (if it has an graphical representation). Its primary used for MasterRenderer calls.

Overrides:

onRender in class GameObject
