Pretty cool image. My first thought would be to shoot particles inside the object with collision and use Tracer to produce splines from the particles paths -- then sweep the splines. You could use Hair splines for the more orderly strands.

DiTools comes to mind

Just for fun -- using TP/Tracer as outlined above:

Wow, Adam, that was quick! :thumbsup:

Excellent Adam! Would it be possible to share an example file? I'm gonna give this a try myself first, but am not sure if I understand the exact procedure you describe.
Anyway, thanks for posting!

Oooo, looking forward to dissecting this! Thanks Adam :thumbsup:

dissecting too. But I don't understand why I cannot change the collision object into my own object. I change it in Userdata> Collision Object but the particles just fly through. I must be missing a setting somewhere?

You've got to reverse the normals of you object.

[ooo]

Yes! Very obvious indeed but also easy to forget. Thanks again Adam!

Hello
Thank you very much adam. I play with it and its really nice and i wanna only know how i select second (m small) object as a second collision object ?

Thanks

Thanks Adam,

If possible, one member is doing a video explaining this lesson ...

Unfortunately .. My English language is not good :shrug: ...

You can create another Pdeflector node and reference your second object. Just connect it to a Ppass(all) node.

Adam, thanks for sharing!

I was thinking that this would make a great way to make the All-Powerful and Mighty Flying Spaghetti Monster. Just remember the 3329.3rd commandment: Thou shalt not worship the image unless it contains pesto or red sauce.

And, Thanks, Adam!

Adam - where is the shape of the "object" defined. I see the sqaure and the Pshae node but Pshape gets its input from the Shape output of the Emitter and I don't see where the Square is actually defined.
Point wouldbe to try some different shapes (Otto, just for example) for the "extrusion" ad I'd love to know how to change the shape.
thanks much.

I used the TP Collision preset as a shortcut. You just click on the "TP Object Collision" object in the OM and all the properties appear in the AM under the user data tab. There's a "Collision Object" slot where you can drag in the object of your choice.

If you open up the Xpresso on that object you can add additional colliders. You just have to create extra PDeflector nodes (New Node>TP>Dynamics>PDeflector). Connect the existing P Pass node's output to the new PDefector's input. Then click on the deflector node and in the AM you'll see an "object" slot where you can drag Otto (or whatever). Set the deflector type to "Object".

Note: if you use a PDeflector node you don't actually have to reverse your object's normals -- you can instead choose "Collision Type" back (or "two side").

Looking forward to whatever craziness you come up with. :)

what a great idea and easy to use setup.

many thanks,

wow thanks for sharing Adam. A great and easy setup...

Adam, thanks,
I'm happy to learn something new every day:)

[gildattack]

really nice! tut would be great... though the file is really great already:)

[vid2k2]

Here's a quick test using the v10 demo.
(yea, I know I need to upgrade)

[gildattack]

it looks nice david, though some parts seem to be intersecting with each other, is there a way to avoid this?

Thanks. I don't think there's collision detection using the sweep.
What's interesting is that each time you run the sweep, it turns out
different. Move the Emitter this way or that, and it's another image.
Same goes with adjusting any item in the various fields.

Hope tht helps.

As far as any tut, it's really simple. As I've explained to mohammedbood:

Just take the file that Adam posted.
Click the Object Collision ...... see the Cube in the field ?
OK, take your object, anything that has no holes,
(holes allow the TP to bounce out of the shape) and drag
the name into the field .... replacing the cube.

Make sure you position your object so that the Emitter
is inside your object.

From there, go to animation layout and press play.
You'll see that the frames are 500. You can make it longer.

Hi Adam,

Your methodology and example rendering are great. That's some nice out-of-the-box TP there (emphasis on the Thinking). :thumbsup:

[vid2k2]

For those that need a little more help.

Thanks again to Adam for posting the file.

[vid2k2]

That's it.

This is so cool! I notice when it's animated that the tracers only update once a second (at 30fps project settings) -- making for some choppy animation.

How can I get them to update on each frame for smooth animation?

Adjust the "Sample Step" setting in the Tracer parameters. Setting it to 1 mean that Tracer will update every frame of animation, thus a smooth animation.

This is so fun. Who knows, Adam? You may even get Meats Meier to switch to C4D with this little baby ;)

Had totally forgotten about being able to do this style. I remember when JoelD posted his great example using Cidertank's LOCO and particle tracer...

Great stuff.

Thanks Adam

This is so cool I have to find a way to use it on a project.

[tonare]

Is there a way to make the particles start out going straight instead of going all directions?



Thanks Adam, this is good stuff. :)

[mohammedbood]

Thanks for Adam,David & all Members ...

[AdamT]

Sure, you just have to adjust the spread in the emitter object's properties.

Thanks man, that was a no brainer lol.

[djblueprint]

Really great, thanks for you work!

[soccerrprp]

Am I missing something? I pressed play and don't see any of the splines forming/formed?
