algorithmic modeling for Rhino


I need a little hand with a project of mine.

I'm trying to create a diagrid surface that is organized into frames and panels. The panels will be windows and the frames surrounding them will be extruded to shade these windows. The goal is that I could control the depth of the frames at each of the diamonds' 4 points with 4 different numeric sliders. Once this is done, I plan on having the extrusion distance of each point correspond to the path of the sun.

Using LunchBox, I already have part of the solution, but it only controls 1 of the 4 points, and the extrusions are just flat planes without any depth. I'm wondering how I can improve this so that all 4 points can be adjusted independently and the whole panel shape responds accordingly with an actual thickness.

I've attached the grasshopper definition I've been working with and would be glad if somebody could point me into the right direction.

Replies to This Discussion the opportunity (and having absolutely NO intentions to criticize your design approach) some notes:

1. Things in Eco-Architecture are heading towards "solid" state solutions. Any solution is judged by that Investment Break Even Point thingy (nobody gives/spends more cash if the EBIP exceeds, say, the accepted 5 to 8 years span).

2. Variable tint is near "mass" production: the so called Smart Glass.

3. Smart Glass is a laminated product either in glass or polycarbonate that appears opaque, like frosted glass, when non-electrified, and becomes transparent once an electrical current is applied.

4. Composite PV panels are fast becoming affordable (the next global economical crisis could greatly accelerate things, and/or the transition from carbon to hydrogen economies).

5. So, for a relatively large span tower that has a skin made from some semi-structural system (avoid structural AT ANY COST) we could use a vertical grid of, say, 0.8m. That could yield 3 "smart" module zones for the habitable spaces (2.4m free height) and 2 PV zones for the PhotoVoltaic - PV job (1.6m nominal height) giving a 4.0m floor to floor that is within reasonable limits (3.6 to 4.8 is the normal "bound"). Personally I use 0.9m giving 2.7 and 1.8 = 4.5 floor to floor.

If you combine all the above: well ... it's obvious what is the trend for the near future.

PS: For the next big thing:

Is the grasshopper file still available?
