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, 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.

Hi Wang is there any tutorial about the using of PedSim please?

Hi, chrisk,

Thank you for the feedback. Unfortunately I don't think the current version can extract FanVision geometry or collect objects in people's field of view. I'll think about it.

Great plugin, thanks for sharing

I want to use the Persons' FanVision to define what objects are within a persons view. For this it is useful to have an option to extract the FanVision geometry as an option in DeconstructPerson. Any thoughts if this is possible, or how to use a work-around for this 0.07 version

Thanks Peng. Oddly, restarting alone resolved points 1 and 2...

Great work-around idea for prioritising - It does the trick for returning to the more linear style of v0.06 when needed

Hi, William,

Thank you for the feedback! I'm glad you find it useful.

1. Please right-click on the DrawPerson component and turn on FOV.

2. I'm not sure what is wrong. You can email the files to me and see if I have the same issue.

3. You can use FanVision and control the distance that a person can see. This can allow a person to prioritize targets that are near.

Hi Peng,

Good update! The parameters are definitely easier to compile than previous and the movement/interest-attraction are much more natural. Thanks!

Below are a few issues I’ve run into with my own layout. The whole file was rebuilt using the new components (as the legacy ones created errors).

  1. Visualisation of Pedestrian FOV no longer shows up (using FanShapedVision). Worked in 0.06.
  2. Gate Names and Ped Numbers do not show on my builds, though are visible on your examples. Worked in 0.06. Any ideas?
  3. The introduction of the new queue priority and lack of deliberate interest-prioritisation means a multiple-stop path can no longer be faked. Any v0.07 tips on forcing Peds from one point to another in order?

Many thanks,

PedSim V 0,07 is released. Person's movement is more realistic now and it solves some of the problems discussed here. Please check it out!
