Thermal Comfort

Is it tough to instantiate a thermal comfort calculation through Lua?  From what I can tell it is not accessible through any of the components.  I was curious to test different tools (e+, etc) and compare thermal comfort.  From what I can tell, Ecotect is one of the tools that allows you to visualize the thermal comfort in a room, whereas e+ (through DIVA) can calculate the cooling an heating loads to achieve thermal comfort as a metric, not a spatial calculation.  Of course, I am by no means…See More

Applied Parametric Design with Grasshopper 3d at Beirut, Lebanon

April 11, 2014 at 6pm to April 13, 2014 at 6pm
The workshop on Applied Parametric Design serves as an introduction and immersion into the world of associative design with McNeel’s Rhinoceros and Grasshopper software. Rhinoceros is an advanced Nurbs modeller. Grasshopper is an associative modelling plugin for Rhinoceros that allows us to parametrically define the logics of our model in order to explore variations and optimized solutions. These two tools are a powerful combination for any architect, designer, engineer, professional or student…See More

Hello Luis, fine to meet you here! After a long time of abstinence I am really glad to have some spare time to work and play with grasshopper again. Recently I did attend a course given by Steffen Riegas in Berlin for working with the VB Script Component. That opens new dimensions for me - but is not so easy for one who did learn programming before the OOP era..

I hope you are fine and send you my best wishes

Hi Luis,

Thank you for your continued grasshopper contributions. I was interested in having a chat regarding kml component. I too would be interested in having more control over color, camera and adding custom data.

hey, I saw that you were checking with elk about using api for more nodes instead of just the xml data osm file, and I saw that you did a test run and it looks great, I am trying to do some diagrams for a project that I wam working on and I need more details like you got in your test run, would you be able to send me the file that I can edit to my longitude and latitude to get all the info that I need?  Thanks

Can we send data from grasshopper in one pc to grasshopper in another pc linked with lan using ghowl, to more processing... if yes, how? and will it be able to update the data stream if e change the parameters in the first pc? 


Is there a primer or a document/video of some sort as a tutorial...since m new to ghowl ?

Hey ,  Is it possible to connect two stand-alone PCs (clustering) , for higher processing and more ram space through ghowl?

Your Hexy grid definition was very useful to create my Pave builder for jewelry. I have posted it on the GJD3D website check it out and let me know what you think.

Thanks for sharing your ideas!

Control Rhino Sun System from GH (Rhinocommon)

In Rhinocommon it is very straightforward to take control of the sun system.

The attached definition will get you there.  There are some weird things happening when I switch locations...the time gets shifted.

I need to look further as it was very quickly implemented.  As you see, only 2 lines of code to mess around with the…
