Hello,

I'm going to graduate in building engineering and architecture at Politecnico of Milan.

I'm using DIVA+Galapagos optimization for the shading skin of my final thesis.

I create a grasshopper definition that allow to Galapagos to find the best compositing solution of the panels in the attached files.

The skin is composed by glass panels, covered with a ceramic pattern that have a shading function; i have to approximate the ceramic shade to a rectangular form because the pattern is too complex for the optimization in galapagos.

I supposed that I have to create a custom material with the ceramic proprieties, but i have to consider that the geometry that i used for the simulation is an approxiomation, so probabably i have to set a "transparency" parameter to the custom ceramic material. 

Anyone know how I have to set the custom material to have this approximation?

thank you

Hello Massimo,

I would use the trans material with a set reflectance and transmittance to resolve your shading panels. This forum thread and page 21 of Axel Jacob's Radiance cookbook (on the Trans material) are good places to begin.

Best,

Alstan
