Method Detail

moveCameraZ

public void moveCameraZ(float direction)

Calculates how far away the camera should be from the 3D model

Parameters:

direction - The zoom factor - (+) indicates moving towards the model (-) indicates moving away from the model

moveCameraXY

public void moveCameraXY(float tx,
                         float ty)

Pans the camera across the model

Parameters:

tx - The x-translation, in screen pixel space

ty - The y-translation, in screen pixel space

Returns an array of the camera's position coordinates

Returns:

A vector representing the camera's position

getLocationViewVector

public float[] getLocationViewVector()

Returns an array of the camera's view coordinates

Returns:

A vector representing the camera's view

getLocationUpVector

public float[] getLocationUpVector()

Returns an array of the camera's zoom coordinates

Returns:

A vector representing the camera's zoom

hasChanged

public boolean hasChanged()

Let's us know if any of the camera's values have changed

Returns:

True if the camera changed, false otherwise

setChanged

public void setChanged(boolean changed)

Used to indicate whether or not we want to let other objects know the camera's value has changed

Parameters:

changed - What the "changed" field should be set to
