Graph mapper - parabolic beams transition

Hey guys,

I want to create parabolic beams between the two edges of a roof, where there is a transition in the amplitude/curvature of the parabolas from one end of the building to the other. I tried to use graph mapper to do this, so that I could Control this, but I cannot make it work. I can only get the same amplitude/curvature for all the beams.

Hoping you guys can helpt me :)

So there was a lot going on in you file so I just aimed for what I think you are trying in principle.

Is this close?

Good luck!

Hey Jonathan. Thank you very much for the answer. Yes, that's what I want to achieve (just With a reversed parabolic shape). But the thing is that I have to use the two existing line roof lines, and create the beams in between them. I am only able to move the center point of the each beam downward in the same amplitude (move the center point in the z-axis), but I still cannot make a transition from one end of the roof to the other. I tried to use the scaleNU + the series Component to increase the amplitude from the narrow end to the larger end, like in the file that you sent me, but I was not able to make it work.

Best regards,

Gestur

I have grouped the geometry in a red-pink color :)

OK so like this? The nearest beam is not effected by the transformation and the furthest is effected the most. The issue is that we are reducing the Z but your beams are not horizontal to start with so by dragging the z we are not keeping the curve parabolic.

Hey man, thanks again for replying. Yeah I think might have it there, but I cant seem to figure out what that last Component is? the one that goes into the b input in the subtraction Component. Could you send med the files :)?

See attached, it the flip matrix component.

My man ! Thanks you so much Jonny. You wouldn't believe how much time I spent trying to make this work. Now I have Control over the Whole structure. Here is the whole structure :)

Thanks again Jonny
