Re: Vector scaling

Hi John

_From any of your ScalarMaps to Flow1X, Flow1Y, Flow1Z or
Flow2X, Flow2Y, Flow2Z :

ScalarMap flow1x_map
FlowControl flow_control =  (FlowControl) flow1x_map.getControl();
flow_control.setFlowScale(float scale)

You'll have to fiddle with the scale value, I think the default is 0.02
