You could constraint the particles to a curve using point cloud search in a VOP POP.

There is at least one other simpler way to achieve similar result. I'll try and post a file later.

You could replace the Attribute Transfer POP with a POP VOP (DOP?)
Check the attached file for a rough example.

Houdini Lounge » RBD-Distance between Objects

Hi,
I believe it has something to do with the collision representation of your RBD objects as it is in your file.
Go in the bullet data tab on you RBDs and switch the Geometry Representation to sphere on the sphere object and plane on the grid object and it should work as expected.

i have a solid object FEM and i'm trying to find vertices/points that exist on the outside surface only.
any ideas?
Can you post a file? At what point in the network do you need external points? You could create a point group before the object gets tetrahedralized and this group will still be there after the simulation.
Hope this helps.
Cheers
Houdini Lounge » question about buying houdini and upgrade prices
- rafaels
- 696 posts

If you get the Anual Upgrade Plan, you'll get all the upgrades and new versions for the duration of your coverage. If you choose to renew your AUP every year it's cheaper than the full houdini price, but if you stop it for whatever reason you'll have to pay full price in order to get in the AUP again.
I think that's about it, if I understand well.
You should contact support if you have more specific questions or case scenarios.

Technical Discussion » Try to use point cloud to add color
- rafaels

Hey,
Save your point cloud to disk as a .pc file and it'll work. Also when you test it out, make sure to adjust your radius (0.8) worked nicely for me.
The trick here is that the op: expression doesn't evaluate in the shader context, you need to explicitly point to a file in disk.

This pop change basically made 90% of the tutorials out there useless which is a shame..
Progress requires sacrifices… you could scatter points in your volume prior to sourcing your particles.
You could also use the fluid source SOP and source particles from it… endless possibilities!

You could use the blendshape SOP, but then you have to make sure not only the point count coincides, but also the positions are correspondent.
One way to achieve that would be to place the sphere inside the box and ray SOP the sphere onto the box. Won't always be perfect but depends on how you're going to use this.
Other ways to do the same effect would be using particles, volumes, or fluids but that's for later down the road…

Please, take no offense, -heavy-, but there's usually a number of ways to do something in houdini. Few of us can spare the time to watch the tutorial you mentioned and would be helpful if instead of guessing how you got to your issue, we could look at your setup and be: AHA!

…You're still going to run into some of the inefficiencies of Apple's GL2.1 driver as we have not migrated to their core GL3 driver for H13.
I believe one GPU is reserved for graphics, and one for compute. As our CL support is disabled on the Mac due to driver issues, that means Houdini will only ever use the one GPU. But since you can't get a new Mac Pro with 1 GPU, that's a bit of a moot point.
Bummer…

Thanks for the hijack, Tricecold, but I guess the question is “what is the new macpro like for houdini?” not “what would be a better machine than the macpro?”, to which we all know the answer, more or less…
I'm also curious about this one. Not that I would ever buy it though…

My cloth objects all have this warning:
Warning: Skipping unrecognized parameter “copyinput”.
Warning: Skipping unrecognized parameter “labelparm5”.
I'm at a point where the cloth is exploding but I can't tell if this is the cause. It also doesn;t seem to like negative frame range and “import target geometry”. It's a recipe for explosion…

Within the geo container place a transform SOP and put $CEX, $CEY and $CEZ in the pivot channels and -$CEX, -$CEY and -$CEZ in the transform channels. That would bring your geo to the origin based on it's centroid. Then you try the right-click/save as.

You can probably tackle some of these imports with python, right?
There's a SOP called Import Table that handles CSV and it's written in python.

Technical Discussion » Alembic extension getWorldXform seems to lag a bit
- rafaels
- 696 posts

I have an alembic cache and I created a python SOP to extract transforms from it and apply to another object.
It seems though as the objects that load the transforms from my alembic cache won't move exactly in sync with the actual cache. I'm not sure if it has to do with how the python method (getWorldXform) interpolates the transform (which seems to be linearly) or a performance drawback.
Has anyone been through the same situation and can give me some advice?

Please make sure that if you're adding to this thread that you also log an RFE in our bug database because that's the only way your issue will actually get logged, tracked, and assigned to a developer. Thanks!
Are you saying we can't just sit back, dream on and hope our thoughts get picked up from the ether… that's too bad!
