Export Grasshopper LadyBug Simulations to Realtime platforms

Exporting color scale renderings from Ladybug simulations outside of Rhino after baking can be challenging as most formats tend to lose the colored information. What steps can we take to address this issue?

Grasshopper result

Bake the results from Ladybug.

Export Grasshopper LadyBug Simulations to Realtime platforms

Export the 3D file to WRML

Check Vertex Colors

Open Blender

Import the WRML file

Export Grasshopper LadyBug Simulations to Realtime platforms

The file arrives black

Change Material to Attribute to see the color gradient

Export Grasshopper LadyBug Simulations to Realtime platforms

Transferring Attribute to Texture

First unwrap the geometry

Select shape -> UV Editing

Object Mode -> Edit Mode

Export Grasshopper LadyBug Simulations to Realtime platforms

Be sure that all faces are selected (it should be orange)

UV -> Smart UV Project

In Shader Editor

Add a Color Attribute, Right Button click to reveal Col

Link Color to Base Color

Export Grasshopper LadyBug Simulations to Realtime platforms

Add an Image Texture

Click New and choose 2048×2048 resolution

Export Grasshopper LadyBug Simulations to Realtime platforms

Click OK

Switch Evee to Cycles

Grasshopper LadyBug, solar panels

This is a quick set up to understand how to orient solar panels for maximum efficiency using Galapagos’ generative capacities.

Load EPW file from https://www.ladybug.tools/epwmap/

Use FilePath to get the file from where it has been stored.

Connect the SunPath

We add a date, to start it will be a single date, but we will work a period a time afterwards.

We evaluate Direct Sun hours

Geometry is the surface to be calculated, Context refers so objects casting Shadows

Connections

We run

This is the result for a single day June, the 21st at 10 am

Now we check for the same day from 6am to 6pm

And we have quantities. For every square of the grid, a total of direct sun hours

The have the total we can have a Mass addition

Adding a solar panel

We will search which orientation is best for a solar panel. To get faster results, we will only test two orientations

We add the LB Incident Radiation Component and its dependences

A Solar Panel is created, and we will git it the possibility to rotate X axes and then Y axes to find the better orientation

This is the solar panel

This how we can prepare the rotations

To go faster, we will investagate every 5° between -90 to +90. For that we prepare the slider as shown below. 18*5=90. So we go from -18 to +18 by 5

The Solar Panel becomes the new geometry, the grid has to be reduced, we try every 0.25m

We test for one day, one orientation

Ok, for one day, let test the best orientation

We add Galapagos component. Genome goes to the Slider and Fitness to the mass addition number obtained from the results.

Double click on Galapagos, we choose Maximize, because we are searching for the best result

Then Solvers, start Solvers

As our ground is pretty free from constructions, with no surprise, the best orientation here is horizontal (and we’re in June !!)

Other orientation…Facing south the best orientation is 20°

Milwaukee Art Museum Grasshopper solar animation

Inspired by the Milwaukee Art Museum Grasshopper reconstruction – solar animation

The Quadracci Pavilion is the iconic sculptural addition to the Milwaukee Art Museum designed by the Spanish architect Santiago Calatrava. Highlights of the building, completed in 2001, are the magnificent cathedral-like space of Windhover Hall, with a vaulted a 90-foot-high glass ceiling; the Burke Brise Soleil, a moveable sunscreen with a 217-foot wingspan that unfolds and folds twice daily; and the Reiman Bridge, a pedestrian suspension bridge that connects the Museum to the city.
