Performative Heart Valve Like Dynamic Thermal Control Canopy, for COMMUNICATIONS 3, Design In Architecture @ Sydney University (USyd)

Hi everyone

I'm a student studying Design In Architecture at Sydney University (USyd).I’m currently creating a workable performative system for a subject called Communications 3. I'm hoping to have it done up and running on May 2nd. I'm looking at creating a canopy to control the amount of daylight access in the space.  

I’m looking at creating openings/holes inspired by the opening and closing function of a heart valve. With the openings/holes, I want the openings/holes to be controlled by an attractor point, with the attractor point represented as the sun. I want to look at different scenarios during daytime whether it’s in the morning or afternoon.

My intention is to create openings/holes similar to the ones from the video tutorial on how to create a circle pattern based on point distance by d.fano. (except that the circles are resembled as eclipses to resemble the heart valve openings)

However Reza Eslami has created openings/holes from Dynamic 01 and Dynamic 02 which are similar to what I want to design for my openings/holes. Except look at resembling similar to the heart valve. Have a look at the links so that you understand what I want to create.

I have some questions in mind on how I can design my system, here are the following:

1-  How would I apply openings/holes in a complex surface similar to the one in the circle patterning based on point distance tutorial by d.fano?

2-   What methods I can use to represent the attractor point as a sun?

3-  How would I apply openings/holes in a complex surface similar to Dynamic 01 and Dynamic 02 by Reza Eslami?

4-   Are there any tutorials on how to use GECO? What components, scripts or definitions I need for GECO to work? I would like to use this program to analyse how much daylight is accessing the space.

It would be greatly appreciated if you can provide some valuable advice on how I can create my system. In the meantime, I’ll keep on developing my system. I'll try and upload my Rhino model/Grasshopper definiton of a test array I did (with the guidance of a tutorial by d.fano)as well. Cheers.
