void setCamera(com.badlogic.gdx.graphics.PerspectiveCamera cam)

Sets the active camera

Parameters:

cam -

getCameraStereoLeft

com.badlogic.gdx.graphics.PerspectiveCamera getCameraStereoLeft()

getCameraStereoRight

com.badlogic.gdx.graphics.PerspectiveCamera getCameraStereoRight()

setCameraStereoLeft

void setCameraStereoLeft(com.badlogic.gdx.graphics.PerspectiveCamera cam)

setCameraStereoRight

void setCameraStereoRight(com.badlogic.gdx.graphics.PerspectiveCamera cam)

getFrontCameras

com.badlogic.gdx.graphics.PerspectiveCamera[] getFrontCameras()

getCurrent

ICamera getCurrent()

getFovFactor

float getFovFactor()

getPos

Vector3d getPos()

setPos

void setPos(Vector3d pos)

setDirection

void setDirection(Vector3d dir)

getInversePos

Vector3d getInversePos()

getDirection

Vector3d getDirection()

getVelocity

Vector3d getVelocity()

getUp

Vector3d getUp()

getDirections

Vector3d[] getDirections()

getNCameras

int getNCameras()

getTranslateUnits

double getTranslateUnits()

update

void update(double dt,
            ITimeFrameProvider time)

Updates the camera.

Parameters:

dt - The time since the las frame in seconds.

time - The frame time provider (simulation time).

updateMode

void updateMode(CameraManager.CameraMode mode,
                boolean centerFocus,
                boolean postEvent)

getMode

CameraManager.CameraMode getMode()

updateAngleEdge

void updateAngleEdge(int width,

Whether the body is focus

checkClosest

void checkClosest(IFocus focus)

Called after updating the body's distance to the cam, it updates the closest body in the camera to figure out the camera near

Parameters:

focus - The body to check

getClosest
