Constructor Detail

ScalingAction

public ScalingAction(VcObject v,
                     TransformMode mode)

Creates scaling action given VcObject to act upon and transformation type.

Parameters:

v - VcObject affected by action.

mode - can be either absolute or relative.

Method Detail

setScalingValues

public void setScalingValues(double x,
                             double y,
                             double z)

Sets new scale values in all three axis.

doAction

public void doAction(ActionExecutor executor)

Description copied from class: VcAction

Performs the action.

Specified by:

doAction in class VcAction

Parameters:

executor - provides any resource necessary for the action execution, such as references to other objects.

optimize

public boolean optimize(VcAction inputAction)

Tries to combine the effect of this action and of inputAction into one single ScalingAction. When optimization is performed only this action should be executed, and not the inputAction. return true if optimization was performed, false otherwise.

Specified by:

optimize in interface camera3d.action.OptimizableAction

Specified by:

optimize in class TransformAction
