Re: strands generated on points

Hot damn that worked! Thanks!! Tried to set it to points initially but it
didn't do anything unless I cranked it super high, makes sense now.

Re: strands generated on points

[Steven Caron]

Wow, been a while for me but... Don't use Emit On Surface and instead bring
in the mesh, plug it into a get data (set to point position) then plug that
into an Add Point node. That's bare bones so you'll need to init some
variables for simulation... Ie. Mass, size, shape, etc

Re: strands generated on points

[Jens Lindgren]

This one is easy :)
First, in you Emit from Surface Compund set Select Rate Type to Total
number of Particles and set Emission Type to Point. Rate doesn't really
matter when you want to emit from mesh vertices.
Then the secret sauce... Go in to your Emit from Geometry compound, then go
in to Generate Points compound. In there, bring up the Generate Sample Set
node properties and set Rate Type to All Points.
Tada!

Re: Strands colliding and sliding on moving mesh?

[Andy Nicholas]

Easiest way to smooth a strand is to do the following for each strand point:

p(n) = A x p(n) + (1-A) x 1/2 x ( p(n-1) + p(n+1) )

Where:
p(n) = Current strand point position
p(n-1) = Previous strand point position
p(n+1) = Next strand point position
A = Smoothing factor (from 0 to 1)

For best effect, do this for a number of iterations keeping A as small as you 
can.

You can get better results averaging over more neighbouring points in the 
strand and weighting them using an appropriate filter (Gaussian, etc.)

Re: Strands colliding and sliding on moving mesh?

[Olivier Colchen]

Hello,

To be honest, I think you're both right : it's probably not worth the time,
especially considering I don't even have a month to setup everything
properly in each scene and then render it. And only a handful of frames
would actually benefit from that. I barely tried the dynamic framework
solution, as, as you mention Stefan, it seems to only really work on
fixed-length strands, as well as setting up some flex/stretch I don't
really want. And devling deeper into the system looked time-consuming.


However I believe I was quite near the result I wanted, going back to the
simple Closest Location to strandposition compound. Maybe I could find the
middle solution and smooth the strands whenever they leave the volume to
fix the little dents appearing here and there. I have no idea how to smooth
a strand, though...

Agreed. I doubt it would give you a look that you want and probably isn’t worth
spending too much time trying to make a robust system to make it work. Do a few
quick tests first to see if it’s going to take you in the right direction.

As a quick alternative, why not try setting the StrandColor to black for any
strand points that fall inside your collision geometry, and then incorporate
that as a multiply operation into your shader? That'll hide any parts of the
strand that go inside your character.

Re: Strands colliding and sliding on moving mesh?

[Stefan Kubicek]

Hi Olivier,

I think there are example scenes for strand collision that ship with XSI. No 
friction between strands and geo is modeled as far as I can remember, but it 
might get you started.

Then there is also the strand collision framework for more accurate collisions, 
but I don't know how it reacts to changing point counts and strand length: 
http://softimage.tv/strand-collision-framework/

PS: If the runners trails are meant as a graphical element rather than an 
actual physical element in your picture I doubt I will look nice when it 
collides with the runner. Maybe you could solve this in comp and get around 
explaining collisions entirely?
Here is a nice example in a recent Glassworks spot that might be similar to 
what you to try to achieve:
http://softimage.tv/lycra-moves-you/

Good luck,

   Stefan





Hello, long time reader, first time poster here!

So I have a bit of a problem on my hands.

We are doing a very simple concept, a sportsman whose back is leaving strand 
trails as he goes. This is child's play so far.
My issue is that we would like the trails to interact with the mesh when, for 
various reasons, he cuts through them again.
IE : at some point he falls to the ground and stands back up. The unwanted behaviour 
is that the strands generated from the back of his head will >simply go through 
his head as he rises up, resulting in a somehow vertical strands column masking his 
face and fore-body. The desired behaviour >is that the strands will flow around 
his cranium, maybe along his back, effectively leaving at least his face apparent.

Animation is done in Maya and transfered over via geocache.

I tried to operate with tools like 'closest location' or 'get location by raycast' applied to 
the strandpositions when inside the volume to simulate >collision, but these were all 
lacking. The raycast solution may be promising, but I don't know how to set the correct 
direction vector. And >sometimes the animation I'm working with may "skip" a 
strandposition, effectively not triggering the 'inside volume' condition.

So yeah basically I don't know how to do that in a visually pleasing way.
If anyone had some pointers, I'd be very grateful !

Thanks,
Olivier

Get all edges
add a particle per edge
use edge vertex index 0 for the particle position (and strand 0 position)
use edge vertex index 1 for strand 1 position

or ;)

go to rray.de and look for this - Strandwire Compound by Andreas Byström

Thanks Alan, I had tried the create extrusion compound, but it doesn't work
with strands created with Generate Strand Trails, all strands have to have
to same number of segments.

No, because you cannot SetTopo on NURBS. Wanna sign that petition... ? =}
Besides that, it would be a trivial task.

I’m attempting a similar approach now. I think it will be the most

generates an array with a dense set of step positions of the curve

I’ve tried using Get Geometry Sample and Generate Sample Set but

looking for. I’m curious though, is it possible to convert curves

Hi Joey,



about the normalized U -  see this thread from 2011 with a rich
reservoir of explanations, techniques, compounds and even an addon
that installs a compiled ICE node that should hopefully give you
what you are after in a speedier rate of milliseconds

https://groups.google.com/forum/#!searchin/xsi_list/Why$20is$20Curve$20U$20spacing$20always$20wrong$3F/xsi_list/7300r-6gRoA/X2ITPQ-d-qMJ

also the gradient along the strand issue.. are you talking about
render time or viewport display?

for use at render - its just a color attribute connected to the
material in the render tree. an array of strand color though so
the attribute particle color will not work but if you are using
build strand from curve it creates an attribute called
'coloralongstrands'  which can be selected in the rendertree

for viewport display of gradient. hmm don't think so but if your
strands are segment dense then you could do a display hack using
another pointcloud to make a gradient from your strands positions
like so (attached jpg)

I'm attempting a similar approach now. I think it will be the most efficient 
way actually. I'm working on something now which generates an array with a 
dense set of step positions of the curve and a conversion of 0-1 to equal a 
relative index on the array. I've tried using Get Geometry Sample and Generate 
Sample Set but have been unable to get either  to work with the density I'm 
looking for. I'm curious though, is it possible to convert curves to linear 
curves within ICE?

RE: Strands

[Ponthieux, Joseph G. (LARC-E1A)[LITES]]

So I've managed to get the strand shading as desired. I used Color_Attribute in 
the material to reference back to the color in the Create Strand From Curves 
node.

I need a way to set the start position of the strand and its length. Hacking 
the Create Strand From Curves has proven to be problematic. Is there any way to 
alter this with other compounds or attributes? I'm finding 
pointcloud.StrandLength, for example, to have no effect.

Hello,

I'm trying to use strands again, and what I want to do is have a strand act as 
a trail along a curve. The things I want to achieve are:


1.   Display the strand along a curve starting at any U location on a curve.

2.   Strand length will need to be shorter than the curve, typically a 
percentage of the length of the curve.

3.   The strand needs to be able to move along the curve linearly, 
regardless the parameterization of the curve.

4.   Strand needs to be a set color and needs to fade out to transparent as 
it reaches the end of the strand.

5.   The strand appearance needs to remain relative to the length of the 
strand as it moves along the curve.

Using Create Strand from Curves I was able to get some of the position and 
length settings the way I wanted by hacking the compound. However, I'm not sure 
this is the best approach. Further, there appears to be parameterization issues 
with the strand position.

I've been unable to figure out how to accomplish the trail appearance.

This is new territory for me so I'm not sure if I am approaching this from the 
right direction. Any suggestions would be appreciated.

Re: strands-heavy commercial gig, LA area

[Andy Moorer]

In my way of thinking remote is remote, either you are physically present
or are remote and where doesn't really matter.

But I'm not the client, just a freelancer myself. I'll certainly pass along
the name of any artist you think is good, and we can let the producer types
decide who they hire. :)

Re: strands-heavy commercial gig, LA area

[Andy Moorer]

... and it will seem like ... 5 years... :D

(They are still getting their schedules locked down, I suspect their "5
weeks" might turn into 8, it's a pretty effects heavy spot.)

Thanks everyone for contacting me. I've got a lot of names now, almost all
remote, don't any of us live in LA anymore?  lol

What I'll do is forward people's names to the producer who's hiring on this
particular spot, and unless anyone says otherwise I'll share those names
out when people ask me about availability etc. I hope it results in some
work for people.

... It's nice studios are showing such interest in ICE. And when I go to
studios which aren't familiar with softimage, I am getting a lot of artists
dropping by interested in seeing ICE. I hope this means non-softimage
people are starting to "get it." We'll see, the lack of available talent is
a big problem, we're spread pretty thin geographically it seems.

Hi gang... ANOTHER strands-based VFX gig, a good studio with a Nike commercial 
(or several actually) in the LA area needs ICE guys. About 5 weeks in January.

Anyone out there, looking? Remote is a possibility. Reasonably complex stuff, 
you'll need to be comfortable with custom ICE dev and strands in particular. 
This is a particularly nice project and I'll probably sign on myself, but it'll 
need a couple of guys at least.

I'm getting so much call for ICE freelancers in the LA area, as well as New 
York it's not funny. I seem to have ended up on some critical mass of 
rolodexes, and I'm turning down work every week.

Worse, most of these studios end up giving up on using ICE simply for lack of 
people.

So if you're in these areas, or if you do remote contracts, contact me, please! 
There's more work here than people available by a wide margin... I hate not 
even having names to give clients, and to have to suggest they shift to houdini 
just so they can fill seats.

There are quite a few Houdini guys around here. There were 41 at Sony alone

RE: strands-heavy commercial gig, LA area

[Matt Lind]

Funny.

We always hear about companies claiming they cannot find ICE artists, but I 
live near LA and don't see or hear about the job postings.  To the best of my 
knowledge there are 3 video game developers within a 10 mile radius of me using 
Softimage.  Outside of that, I know of no one using Softimage for more than the 
occasional side job with/without ICE.  Obviously there's a disconnect in 
communications.

So what is the nature of the ICE work?  Is it strictly particle stuff?  If 
that's the case it would explain why there's a shortage of talent as Softimage 
isn't particularly known for it's VFXuntil recently.

This is a particularly nice project and I'll probably sign on myself, but it'll

I'm getting so much call for ICE freelancers in the LA area, as well as New 
York it's not funny. I seem to have ended up on some critical mass of 
rolodexes, and I'm turning down work every week.

Worse, most of these studios end up giving up on using ICE simply for lack of 
people.

So if you're in these areas, or if you do remote contracts, contact me, please! 
There's more work here than people available by a wide margin... I hate not 
even having names to give clients, and to have to suggest they shift to houdini 
just so they can fill seats.

Really..there are more competent Houdini TDs than ICE? Or just an L.A.

Re: strands and weight maps

[Mathieu Leclaire]

Instead of passing the particle position in your get closest location 
node, pass your strand position. It will return you a location per point 
of your strand position. You can then manipulate your data as desired 
and write the proper value in your strand size.


For transferring strands into Maya, you can use the Alembic 
implementation of Exocortex. Otherwise, you can convert your strand into 
mesh using ICE modeling and export a geometry. If you need it to be 
animated, you're then going to have to point cache it using a format 
that Maya can read.

Does anyone have any suggestions? Still new to this.

Also is there a way to export strands as geometry into maya?

Re: strands and weight maps

Thank you both

Renaud the problem is the sizes down strand here come from the strand
ratio. I need to make each strandsize from the weightmap like this. Any

Re: strands and weight maps

[Milady Bridges]

I'm not sure I understand your question clearly.  If you have a
strandPosition array, and you find the closest location of each
strandPosition to the surface that has your weightmap property, then grab
the value of your weightmap at that location, it should return an array.
You can use that array to manipulate your strandSize.
