Houdini Learning Materials » importing attributes in pop vop

Hey Everybody,
I'm searching for a way to import attributes into a voppop and manipulate them so I could use that attribute once the particles come back in sops. In the old pop setup I would use a get/set attribute vop but that doesn't seem to work anymore.
Anybody an idea on how to achieve this with the new pop system?

Hey thx, that's perfect like you did it and I also know how to do it that way.
But I was hoping that someone could tell me what I'm doing wrong in the shader.
Cheers

Hey, I'm trying to switch some textures with an attribute.
But I cannot seem to get the shader to work.
Any tips somebody?

It's just a simple smoke setup.
I now did a test with build 12.0.681 and I'm getting the same error at the geometry level but not in DOPs.
Bypassing the resize DOP slows down simulation time drastically but rolling back to H11 gl option works fine for me.

Great, thx for that.
I also noticed while bypassing the resize DOP that simulation time increases.
Is there a particular reason for that Jeff?

I'm getting these artifacts in the viewport.
I'm running, mac osx 10.6.8, opengl 2.1, quadro fx4000, 18Gig RAM, houdini 12.0.641
Any idea on how to get rid of it?

First of al you import your source field, then import the density field and create an empty velocity field.
After that you copy your particle velocity attribute “v” to the velocity field “vel” you created earlier. And last you advect your density field by the velocity field “vel”.
Below you'll find an example file that make's it more clear.

On the properties of your mantra node go to Properties/Output and click on the plus button of “Extra Image Planes”.
In the VEX variable you type your shader attribute or just click on the dropdown list to select one if using a default shader.
To give the image plane a different name and path check the “Different file” option. But be sure to change the “Output picture” path from ip to path/filename, otherwise the “Different file” option will be greyed out.

I use it on/off for 3 years now and keep learning new things everyday.
I really like working in Houdini, it's so flexible, but here in Belgium it's hell to find a job as a Houdini artist. Pity!
Good luck with the touch pad project.

Your example reminds me of the pong game.
You can see the endless possibilities here right. You can copy objects to a point cloud and let that object react on an object flying trough that point cloud.
Well glad I could help.
Cheers Landin

You can use the distance() expression to figure out the distance between two points. In the copy node I added a new variable called prox and added the following expression below. The expression calculates the distance between the centerpoint of the small circle to the corresponding point.
You were close.
Cheers
distance(
centroid(“../xform2”, D_X),
centroid(“../xform2”, D_Y),
centroid(“../xform2”, D_Z),
point(“../point1”, $PT, “P”, 0),
point(“../point1”, $PT, “P”, 1),
point(“../point1”, $PT, “P”, 2)
)

Hey guys,
I was running some tests on beveling and I get a strange error when extruding. The normals of the line prims are flipping and I'm not really understanding why.
Anybody an idee?

The easiest way is maybe that if your trigger is an integer with values 1 and 0 you can use a switch node in your chop network to activate a certain part of the network.

Well figuring out distances isn't that hard.
Can you make a small example file of the scene your building than I can have a look this weekend if you like.
