hey all
i would like any advice on making something that looks like fibre optics that should be emitted from an object and move through the world avoiding other objects.
i would like to use particles because the feel needs to be very organic and turbulant and also needs to move around objects, however the render needs to be solid and tube like.
i was thinking of grouping particles based on their emition point and then extruding between the grouped points, however i have no idea how i would do that. this would also be nice because then i dont need a high point count.
anyways
i would love it if any one has any comments or ideas
thanks in advance

I was wondering, since the only Sun Solaris version of Houdini is only available for the SPARC platform, are there plans for a x86 Solaris version of Houdini?
Oh and, could someone post a screenshot of Houdini running in dtwin (Solaris Motif/CDE) perhaps with a dterm window with “uname -a” in the background?

Technical Discussion » how to make constraints
-
- IsStuff
- 237 posts

I am starting out making my first skeletal rig in Houdini. I started in Houdini and thought VEX was the place for constraints and will get around to trying that out but for now I will do it the regular way, now my first step to keep this rig snappy is to not use expressions and keep all the constraints in CHOP's so I am now trying to find the equivalent of all the constraints I am used to in
CHOP's. The easiest way somebody could explain this would be to make a Houdini file with examples of them or write a description…. making a hip file would probably be faster. The constraints I am looking for are..
(the objects should not need to have the same parent)
* translate to another objects position in world space
* translate between two or more objects in world space
(the objects should not need to have the same parent)
* orientate like another object in world space
* orientate like two or more object in world space (using quatonin intopolation)
* aim one axis at another object while not altering the other axises
The reason i natural think to go to vex to for making constraints is because the relationship between objects in space would be best described in vectors. VEX standing for Vector Expression Language just said to me to be Constraints Ahoy! But i am told that CHOP's is the thing for the job and it is the part of the program that is made to deal with 1 dimensional data… go figure!

Hey Guys sorry to bother you guys but i have a problem sloving this particle effect . My problem being is how do i get the particles to spread out and flow in a certain direction that i need it to go? It;s a wide shot of a guy getting zapped into a computer sort of like in Tron.. But it;s not per particle it;s more like glow warp…. i wish i can post the picture to show you guys what it is. But i don;t have it posted on the net… i posted the pic on the list….
Is there any tutorial that can maybe help me out. Or if any one knows how can i create this effect… Would be A huge help…

it looks pretty nice i saw this making of segment and i noticed they used Houdini on it for the 3d an d i take the particles as well … Does anyone know if they did or didn;t and who actually did the movie?

Is it possibe to pass somehow the object deformation to RBD solver. For example I have a bottle in ice cubes and the bottle will morph into a bigger bottle (with some wobble effect) and I want the ice that surrounds the bottle to react properly. I was thinking about RBD but I don't know if it works.

in my houdini, i created bones. i use 2 panes:
pane 1 : viewer(at object state)
pane 2 : network editor (chops state).
the viewer panes display the bones and the network editor display the network of the KIN_CHops. what i want to do is : while working/modify the parameter of my KIN_chops(in pane2), i'll then see and test the movement in the viewer(pane1), but the problem when selecting some objects/bones in viewer, the pane2 (chops) is automatically switch to SOP state and display my currently selected obj. so if i want to edit the kin_chop, i have to go back to chops state and do it over and over again.
i tried to change the ‘panes link’ to different number, but still got the same problem. anyone know how to solve this?
does anyone know where i can find any good houdini tutorial talking about character rigging/animation that is available in the NET?

:shock:
I got the same error. I get it when I load tutorials, and now, I had followed Mr. Buzz on some tutorials on networking a few times and saved my .hip file and was able to open it up yesterday, but today, it gives me the error. At this point, I don't mind recreating things, cuz Im new to this program and to modeling and could use the excersise. I know if I knew that VEX code, Id beable to bust out with my own environment an tools, but “Some day I will…I pray that I will…but Today..yes, Today…Im Just a Bill”
The whole fatal segmentaion error wouldn't bother me so much, but some things are coincidentaly happening in sequence, like losing my ability to veiw my objects in any shade mode reguardless of settings I make in display properties, or the footprint and display flags on the tiles. And I even tried to get around this by using surface normal options to select my unseen surfaces in surface selection mode, but I only get these edge-like normals :cry:
The interface changes with the operators and tools I choose, I know this, but it seems to do random changes aswell. I havn't built a shader yet, or even experimented around with them, but sometimes the program would start up in VOP mode(Whole new can of worms for me :roll: )
with that said, I let you in on a lil secret……IM scared to delete them .pref files. The posts on this site are from last year and Im using the newest version and I know that they had to have made corrections for windows by now,. But, If that is the case, I'll delete em :shock:
I know, I know, Boo hoo hoo on me :cry: Im on my way now tho the Classroom to seek advise. And for the other Beginners, I suggest you enroll in the FREE class that is run by Jason Busby “3D Buzz” @ 3dbuzz.com. This man is awesome!!!
I will never ever give up, and hope you all keep pushing your envelops no matter you calibur of Houdini-ship.
Thanks

Houdini Lounge » advice on pixy dust / nebula looking visuals
-

Hi everyone,
I have kind of ran in to a big crunch for time on a project and could use any recommendations on this.
I need to simulate the look of pixy dust or a nebula. I know they are not the same whatsoever but just want to get at how they would visually look. i.e. really colorful, glowy, mystical, etc..
My thoughts were to do this in pops and i3d (and think this is still probably the way to go) but it has proven to be somewhat difficult to get my cloud to look very thin and dust-like. I want to get it to look very thin in certain areas and very bold areas in other areas and “creases” in the mist.. Also I like the swirlyness they sometimes have… (does that make sense at all?)
Right now I am just using the metacloud shader with i3d and 3d texture fog shader for mantra. I was assuming a low density render with high noise amplitude and low turbulence/frequency.. but not too sure. don't know if i should be going after a lot of particles in this either. I am also rendering out the raw particles in mantra and compositing them with the cloud so i can get some “sparkle” in their..
So yea, I am open to anything. If you've kinda ventured into something like this in the past or just have anything to say, I'd love to hear about..
Thanks,
Dave

I have a file that i can't save anymore with the “Save As” Option.
I can hit straight “Save” which does make another increment and works fine, but even the new file cannot be “saved as”.
I must have accidently made something to that file, but i don't know what.
The error message i get is
“No such file or folder”, even if i want to save it in the root folder.
Anybody ever heard of that problem?
Cheers
