Dear all,

I'm rather new to Houdini and would be very thankful if someone could help me out.

What I want to create is a domino field (toppling stones) from a logo (vector based). I managed to animate a single line of dominos, and could make a field manually by putting stones one by one and row after row, but I'd like to know if someone knows a better way.

So here's what I think the steps should be:

1) create a box and manipulate it to look like a domino
2) import .ai file and make surfaces
3) create a grid of evenly spaced points on that surfaces
4) rotate grid 45 degrees (to let one stone hit two stones in the final result)
5) copy domino box to points

Maybe step 2 should have an own thread, but if someone can help with that too, that would be great.

Step 3 to 5 is the most important part. Any ideas are very welcome and appreciated.

I attached a file where I made the domino (box) and created part of the logo with a surface from a curve. Then I placed points on the surface by a custom uniform scatter instant. That's as close as I could get…

Thanks in advance!

try this
you'll have to play with the orientation of the dominos to get the last ones to fall…just play with the resample SOP and you can add normals to the curve to help…

Hello everyone

I have to simulate a bowling line so as I did here using the RDB packed objects I got my pins simulated but now it goes inside the geo of floor (which is static)

Thank you in advance

you may want to include your actual geometry in your file attachment…
or make a very simple scene file using houdini's geometry

hello all,

im using this domino scene from arctor, but have some question, because i need the dominos not falling from the initial start frame, :

- how to setup initial collision trigger for the dominos, example, i need active rbd dominos, when sphere collide to the dominos it self,and so on..because my dominos setup was on the air, not on the ground…but finally falling to the ground.

- how to setup initial collision trigger when rbd dominos detect any incoming velocity from the sphere, so its not from the sphere collision but, from the velocity from the sphere…

im really sorry for this noob question…thanks.
