algorithmic modeling for Rhino



PedSim is a Grasshopper plug-in that runs simplified pedestrian simulation in Rhino modeling space in real time. It can be integrated in your Rhino workflow for master plan, public space, commercial and other architectural projects, accelerating design iteration and creating new opportunities for design automation.

Hi, Iggletonipip, Looking at your screenshot, it seems that your targets are inside obstacles, and some obstacles may be nested. These are not supported. Please also check all obstacles (only use what you need) are closed polylines on XY plane. If you simply imported drawing from another program, you may need to process it carefully.

I'm trying to do a simple single person pedestrian simulation with 1 target of interest but in a large study area and it keeps crashing, or the people don't make it to the destination gate.

Am I using too many obstacle curves? Any way to reduce the computational power required for the simulation to get it to run?

Hi William,

Thank you for your help I have now completed my simulation using Peng's examples and your knowledge.

Hi Sophie,

You need to create ObstacleCurves out of ClosedCrvs in Rhino. These are assigned via BReps to here:

Use Merge if you've got a ton to collect.

As Peng mentioned below, the quickest way to learn is to begin with his example scripts and build on them.

Could someone help me with a problem I have please. I have set up a simulation using the tutorial however my situation is different from the example and the pedestrians seem to go over the buildings as they can't tell that there is a plan made in rhino.How do I make them avoid the buildings and stick to the roads. If you need any more information to help please ask.

有人能告诉我?为什么在food4rhino  下载的文件不能安装 我用的版本是 rhino6 自带的 grasshopper 版本  ,是下载的插件有问题还是我的rhino版本有问题

Who can tell me that the software can't be installed? l load form food4 rhino .

Thanks,Pedsim0.09 is very perfect APP

Hi, All,

There is an example package available for PedSim on Food4Rhino or here:

If you supported PedSim on BuyMeACoffee before, you will get an email with this package.

Hi, Mohamed, 

I think a good way to learn PedSim is by studying the example scenes and create your own scene in Rhino and GH. If you have any questions please feel free to ask here.
