Hi, are there some ways to make simple gravity physics in rhino, without having to use grasshopper. Yes i know simple and physics don’t look right in the same sentence :slight_smile: But by simple i just need some type of gravity. like on a 3D printer you can (drop to build plate). which somewhat m…

Hi @Rasmus Not right of the bat, no. But instead of asking for gravity, it might be better to explain what you are trying to achieve? Maybe Align or Distribute could suffice? Also, physics will be coming to Bongo 3, so if you have a Bongo 2 license, you can try that out. But Grashopper really isn…

As Jakob says, Grasshopper doesn’t need to be too tricky - this could also be somewhere to use the GHplayer, so a Grasshopper definition becomes a Rhino command and you never need to see the GH interface. Your mention of drop to build plate though makes me think perhaps it’s something even simpler …

[image] DanielPiker: use BoundingBox to get the lowest point Or you can use Align with a single object and use the Bottom option - saves you the BoundingBox step. -Jakob

Also, as mentioned, here’s a version using GHplayer - you don’t need to edit anything in Grasshopper - just type GrasshopperPlayer in the Rhino command line, then select the drop.gh file drop.gh (14.6 KB)

Hi, If you’re on Windows you can take a look at Bongo 3. The user interface may be a bit more what you’re used to than with Grasshopper. Here’s a small example inspired by what @DanielPiker showed with the Grasshopper player. And with a bit more work you can also build more complex asse…

Thanks for all the input. @Normand Thanks for the link. I can’t get the rigid_mesh_collision.gh to work. the script won’t run for some reason. Overall I didn’t know that it was that easy to run GH premade scripts (GrasshopperPlayer). My knowledge of GH is pretty limited. I know what it can do! an…

Hi Joshua I’m unfortunately on Mac so cant use Bongo (yet) :wink:

Here’s one where the objects collide with each other drop_collide.gh (11.0 KB) Don’t expect too much from the collision detection here though. It isn’t very fast and will likely fail on some geometry. For a simple scatter of a few fairly simple non-penetrating objects onto the ground pl…

@DanielPiker Hi Daniel, I can’t get the new script to work. after running it from GrasshopperPlayer it wont let me select anything. If I try with the previous drop.gh I can select the opjetches without problem.

Ah, sorry I think maybe I disconnected something before saving it. How about with this? drop_collide2.gh (16.7 KB) It should be possible to end the command at any point by right clicking.
