I am in the process of streaming moving geometry out of rhino3d into touchdesigner so I can project onto a moving object. I was wondering how touch designer reads units (inches, millimeters, meters) because if you pay close attention to the video I attached, the distance from start to finish is much further physically in touch than rhino3d so I am assuming it is a problem with units of measurement. Is it possible to change this in touchdesigner? Or does anyone know how to compensate for it in Rhino3D? Does Touchdesigner use a specific unit of measurement?

TD does not have a defined unit of measurement. A translation of 1 can mean whatever you want it do, if you want to think of it in real-world units. So it should just be a matter of scaling the units coming in from rhino by some value.
sure, it just seems strange because I am moving the plane based on x,y,z translation values that are taken from rhino. Any clue as to why the distance between say 1,1,1 and 3,3,3 would appear to be different in rhino than touchdesigner? Not really sure how to deal with this…
nevermind,got it fixed, problem had to do with my rhino setup. Thanks!
@malcolm I just confirmed that when a 1x1x1 unit box is exported as an FBX from Touch, it imports in centimeters into both C4D and Blender:
The same is true for the reverse: each centimeter in C4D/Blender, is imported as 1 unit in TouchDesigner.
