 # Shape data export format

Hey there,
I am trying to figure out how I can compute the control points coordinates of a bezier curve from the shape export data. I have not found any documentation about the format used Bezier curve points are exported into:
Point(a,b,c,d,e,f,g,h)
ie: Point(0.564028,0.3672,0,0.5,0.0552642,1.82817,0.481357,1.98354)
So far I have distinguished:
a = xposition of reference point as a ratio of the width. x = a * width
b = yposition of reference point as a ratio of the height. x = a * height
c = ? (not important for me I guess)
d = ? (not important for me I guess)
e = ? some kind of angle?
f = ? some kind of angle?
g = distance of the first control point, but how to compute the value? unit?
h = distance of the second control point, but how to compute the value? unit?
Thanks.

Hi John,

What I am trying to achieve is to use an exported tracked shape to create an animation using a custom tool that draws bezier curves.

I just need to figure out how to get the information to draw my curves Hey there,

I just need to figure out how to get the information to draw my curves Can you tell me a bit more about what your end product needs to be? I am not sure we calculate for that data on its own, but I may be able to find you a workaround. What are you trying to export this to?

I am going to have to discuss this with my dev guys and get back to you. Please stand by!

Was the original question in this post ever answered? I too need to know the format of the bezier curve point data. Thank you.

Let me see if @jps can shed some light.
