I have checked the introduction of Cyclops in Foster and Partner official website, may I know how to use Cyclops to simulate city-scale model (in a more efficient method without crashing my computer).
Hi Suwen,
It’s hard without grasshopper files to know exactly what is going wrong for you.
But a few tricks for large scale models:
- Pre mesh all geometry inside Rhino. So it’s not being meshed in Grasshopper.
- Have good control over the sampling that creates analysis points.
- Join meshes, it’s better to have a few large meshes than thousands of small ones.
- Potentially sideload geometry. For very large context models it can be beneficial to save context geometry into a separate 3dm file and read it straight into grasshopper using the read 3dm component. Then Rhino won’t have to handle all that geometry, just be careful with the Grasshopper display.
Thank you very much for your response. May I ask a further question? If my city model has already been stored in a mesh format, but I only need to perform analysis on the rooftop surfaces, is there a method you would recommend?
Hmm…
Maybe you can filter out all the faces that are facing upwards, meaning all faces with a normal close to {0,0,1}. Then create a grid of points that cover the whole boundary of you geometry and project those points down on the faces you filtered out. Then all points that hit your mesh of horizontal upward facing faces can be included as analysis points.
Don’t forget to still include all geometry as context in the analysis.
