Method Detail

draw

public void draw(GLContext theRenderContext)

Description copied from interface: Drawable

this method is used to draw the drawable, when the context is ready. although the behavior sometimes varies and doesn t always need to have a visual representation depending on the implementation.

Specified by:

draw in interface Drawable

Parameters:

theRenderContext - GLContext

begin

public void begin(GLContext theRenderContext)

begin in interface CameraPlugin

end

public void end(GLContext theRenderContext)

Specified by:

end in interface CameraPlugin

isActive

public boolean isActive()

Description copied from interface: Drawable

returns whether the drawable is active. it is commonly implemented so that the drawables 'draw' method will be ommitted if 'isActive' return false, although this behavior can vary depending on the implementation.

screenToWorldPosition

public boolean screenToWorldPosition(int theScreenX,
                                     int theScreenY,
                                     Plane3f thePlane,
                                     Vector3f theResult)

worldToScreenPosition

public boolean worldToScreenPosition(Vector3f theWorldPosition,
                                     Vector3f theResult)

screenPositionToWorldRay

public boolean screenPositionToWorldRay(int theScreenPositionX,
                                        int theScreenPositionY,
