coordinates in processing?
May 6th, 2006, 3:41am  
hello people, im using pure data for tracking the movement of people in a public space... then im sending those coordinates to a processing program using osc protocol to create a graphic reprepesentation of the people in my processing program... the problem im having is that it seems x,y coordinates in puredata (gem) is not the same as the x,y coordinates in processing... in processing [0, 0] is the coordinate in the upper left of the window and in puredata(gem) [0, 0] is at lower left, so when i send the coordinates to processing from puredata it doenst fit.... my question how can i fix this? is there any math operation or trick ?

many thanx for the help

processing_y = height - pd_y;

this assumes that both have the same "window"-size .. otherwise just flip them right in PD before sending.

best,
