The first version of Abita+ dates back to 2001. Concepts are, in the computer world as in other domains, concepts that are discovered and forgotten, then rediscovered in the belief that they are innovative or original. At the dawn of the 20th century, to explore architectural solutions, there were three ways. The first was to mimic analogical tools and methods. This is the virtual drawing board such as AutoCad for example. The intellectual process is the same as for hand drawing, it is only the ease of corrections, re- editing and duplication that make it a very productive tool. The second path, less known and somewhat forgotten, is that of declarative modeling. In this method, the idea is to start with the expected result and work backwards through the inductive chain.

In this tutorial, the idea is to explore the potential of Isovist for urban analysis. Isovist is the surface or volume of space visible from a specific point. This concept has been proposed by Clifford Tandy in 1967 and then redefined by Michael Benedikt. Isovists are very useful to quantify the perception of urban spaces such as opening, closeness, and also useful to define urban envelopes. Isovists help to with non-intuitive solutions for complex problems.
Now we want to do the same in 3D. We will use the Ladybug components. We will use the LB visibility percent. Continuer la lecture de Grasshopper, Urban Analysis, 3D Isovist
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?
Bake the results from Ladybug.
Export the 3D file to WRML
Check Vertex Colors
Import the WRML file
The file arrives black
Change Material to Attribute to see the color gradient
Transferring Attribute to Texture
First unwrap the geometry
Select shape -> UV Editing
Object Mode -> Edit Mode
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
Add an Image Texture
Click New and choose 2048×2048 resolution
Switch Evee to Cycles
Down to Bake
Bake Type Diffuse
Contribution : Color
Select Texture image panel AND Geometry and then click Bake.
It takes time…
Connect Texture Node to Base Color and activate Color Texture
Secure save the image
Reload if necessary
