1. Figure out what the rule is for the depth variation of your louvers. Is it a bitmap? An equation? A field controlled through attractor geometry?
2. Figure out what the rule is for your outlines. Hand-drawn boundary curve?
3. Create vertical lines through the boundary region, probably easiest to use the Contour component.
4. Divide the vertical lines into plenty of points/segments.
5. Sample the depth rule at all points and offset the points outwards depending on the outcome.
6. Interpolate the offset points using InterpCrv.
7. Either Loft the base lines with the interpolated curves, or create connecting segments at either end and use Boundary Surfaces to create the louvers.
8. Extrude the resulting louvers until you get the sheet thickness you need.

Thanks for the reply David,

i figured it out and scripted till point 3.

as of now I have a set of points which represent the depth of the curves/surface I need on the facade.

I am not understanding how I filter the point which fall only in one plane and pass a curve/poly gon through it.

Can you please elaborate/ guide me towards point number 5.

Thanks,

I was trying to get the depth through this image.

fins should go with the same depth.

Hey,

In the Attachment there is a .gh which holds to different approaches.

- Point Attractors
- ImageSampler

Thanks a ton Mark,

That served my purpose. I will try to study the logic after the project.

Best Regards.
