Re: Setting data on a particle based off data from another particle in the same cloud
Hi Alan, https://dl.dropboxusercontent.com/u/69741069/cross_querying.rar Not sure if this is what you're after but it establishes a relationship between the parent and the clone which enables the parent to later query the clone's attributes and set data on itself. It's quite hacky in that the only way I could quickly get a parent to know which particles it had cloned was via Get Closest Points on instantiation of the clones. In this scene the parent looks up the second strand position in the clone and shows you the resulting vector. I tried to figure out the ID allocation (making assumptions, for example, that the cloned particle would have the next ID along from its parent but that didn't seem to work) and it would be interesting to understand better how ICE allocates IDs to clones. On the other hand, I think it would be more elegant to do your stuff the other way round - it's always much easier to give a clone the id of its parent since it can directly inherit a custom attribute based on the original particles ID and then always find it again using ID to Location. So, in your case, maybe have the strand on the original particle and querying that from the cloned one (using the easier ID to Location stuff)? Julian

No unexplainable bugs( well there was this one time... :) ), no random crashes and defiantly less nights of debugging scenes till your eyes go red and a lot more productivity... All i have to say is that it defiantly changed the way i perceived my work and brought in a whole new level of fun to it :).

The stilts (the leg controls in the cockpit) had anything from 1500 to 2500 separate meshes and on average about 150 segments (solid groups of parts that moved as one.) Once we identified the segments by the end we had a rig of Arnold stand-ins with each segment saved as one ass file, and low-res geo representing that segment constrained to some part of the rig. It then became relatively light to have the standins rigged instead of the full raw geo, and it made it quite easy to replace parts or textures later in the pipeline during or after animation. (Also caching was a piece of cake in this scenario, as we only needed to plot the segment nulls instead of thousands of meshes or pointcaching anything.) On the brain there was procedural pulsing animation driven by ICE deformers. Globules would breathe, a heart-like organ would pump its ventricles intermittently and an intestine-like organ flowed with bulges travelling along its tract. It was gross and (in my opinion) kind of awesome. lol Speaking of ICE, there was a kind of lettuce behind the brain that was also moving a bit. The modeling was done with strips that were procedurally curled and then if I remember correctly the whole thing was driven via Syflex as the brain gently floated. This lettuce thing was handled by another guy on this mailing list, my coworker and friend Jonathan Laborde. Maybe if he's reading this he can give more details of how he used ICE in a few other shots. It was crazy fun project to work on. Fingers crossed that Pacific Rim 2 becomes a reality. :) Anyway, did you guys go see it? What'd you think? Oh and speaking of other movies, we did a ton of work in Now You See Me as well, including hundreds of stadium dudes with our propietary ICE static crowd system, falling/flying money, cg bubbles, an art-directed liquid, lockpicking, flying cards, many vehicles, the projected motiongraphics near the end and a few invisible fx. (I feel like I probably missed something, but anyway, we did a lot.) We were the main vfx vendor on that film, delivering just over 20 minutes worth of vfx magic (pun intended.) Again, Soft Arnold and lots of effects in ICE all throughout. Cheers, -- Alan --
Re: Setting data on a particle based off data from another particle in the same cloud
If you clone the points clone the id into a new attribute, then you know which particle is the parent. And add a attribute that it's a clone. You can use that later to decide not to put orientation values on. Build a set from you tangent, whatever values and then you can select the corresponding value from that set. I'm not in front of a computer right now, but I'll have a quick look at it if you don't get it working.

Re: Setting data on a particle based off data from another particle in the same cloud
@ Julian Leonard, Thank you guys. I will check your scenes and explanations when I get home later. @Ciaran, It does, but only so for the particles with strands. Particles without strands get filtered out of the logic. So even though I can work out the orientation I need from the location StrandPosition's, when I set self.Orientation, it only sets it for the strandy particles, not the others. That's my main problem. How do I force my set on self.Orientation to be on the original particle IDs?

crowdFX and orientation
Hi List I had a quick question about setting orientation in crowdFX in softimage 2013 I have a simple stadium crowd which I can set a custom emit orientation on thorough the initialize stadium compound, but I want all the characters to face looking into the center of the stadium ideally using a null position as the center. I have tried using a crowd look at constraint but I can only seem to access certain parts of there body with this approach rather than there whole body and it also seems to give unexpected behavior to their animation as well. Any ideas would be great. Thanks. Alex.

CrowdFX Define Move questions
Hi All, Am deep in crowdFX world and generally loving it - quite impressed with it. A couple of questions if I may- 1. Is it possible to put more than one action into a define move node? I am trying trot - run - faster run, when I do this, the middle action does not work correctly it seems to lose cycles (some of these actions are several cycles long, not just one exact cycle) - if I change it to two, and have trot - run - then the run works as expected. 2. Is it possible to change the speed at which crowdfx blends in the motions included in the define move setup - I see in the legacy stuff you were able to change this speed setting, but I cannot find it now? I am asking as my current trot would be nice if it held a tad longer. I am guessing if I speed it up a little it might work - i.e. the action as I am guessing the reason that the original options were removed was the system now thinks it is clever enough to make the switch when the actor gets to the speed that the action was at anyway? 3. Is there anything that I can use to flag turning? i.e. would love a default attribute that I could use to trigger a lean or something like that? Thanks Sandy
RE: Setting data on a particle based off data from another particle in the same cloud
It would be easier to do this with two separate clouds. If you clone the first cloud's points on emission, then the creation order and therefore the point indices will be the same so you can use Switch Context. You can set the cloned particles' size to 0 if you want to hide them and then trigger them some time after emission. Otherwise... 1. Store the ID as a custom attribute, say ParentID, before cloning. This will get cloned and establishes a correspondence between parent and child. 2. Clone. 3. Use Build Array from Set to put ParentID into an array. Find the parent's ParentID in the array. You should get an array with two indices, the one that isn't the parent is the cloned child (safe to say it will be the second one). 4. . Use Build Array from Set again to put the tangents into an array. Use the child's index to get the tangent you want. gray From: softimage-boun...@listproc.autodesk.com [mailto:softimage-boun...@listproc.autodesk.com] On Behalf Of Alan Fregtman Sent: Wednesday, July 17, 2013 9:45 AM To: XSI Mailing List Subject: Re: Setting data on a particle based off data from another particle in the same cloud @ Julian Leonard, Thank you guys.

blend of speed using test inside null

I'm using the 'set new speed' and then testing inside null to alter the speed of the particles - but is there a way of having the speed animate between the two speeds rather than being a black and white 'if' but rather blend between the two over a specified distance or number of frames?

Re: Maths problem (barycentric coordinates)
BTW here is our code for calculating barycoordinates from points and
creating points from barycoordinates:
templateclass T
class Triangle3 {
public:
Vec3T a;
Vec3T b;
Vec3T c;
Matrix44T getPointToBarycoordMatrix() const;
Matrix44T getBarycoordToPointMatrix() const;
};
templateclass T
inline Matrix44T Triangle3T::getPointToBarycoordMatrix() const {
M44x pointToBarycoordMatrix;
bool success = inverseSafe( pointToBarycoordMatrix,
getBarycoordToPointMatrix() );
if( ! success ) {
T oneThird = ((T)1.0)/((T)3.0);
//Vec3T center = ( a + b + c ) * oneThird;
return Matrix44T(
0, 0, 0, 0,
0, 0, 0, 0,
0, 0, 0, 0,
oneThird, oneThird, oneThird, 0);
}
return pointToBarycoordMatrix;
}
templateclass T
inline Matrix44T Triangle3T::getBarycoordToPointMatrix() const {
Vec3T n = normal();
return Matrix44T(
a[0], a[1], a[2], 1,
b[0], b[1], b[2], 1,
c[0], c[1], c[2], 1,
n[0], n[1], n[2], 0);
}
And this you just multiple your point by the pointToBarycoordMatrix
matrix to get barycoords. And if you have barycoordinates, multiply
it by getBarycoordToPointMatrix() to get your point.
We are using 4 coordinate barycoordinates where the fourth element is
the distance from the triangle plane in the normal direction. Just
set it to zero and you should be fine. The above can be converted to
Softimage Matrix types pretty easily. Probably could be added to the
Softimage SDK as well if it isn't already there.

And this you just multiple your point by the pointToBarycoordMatrix
matrix to get barycoords. And if you have barycoordinates, multiply
it by getBarycoordToPointMatrix() to get your point.
We are using 4 coordinate barycoordinates where the fourth element is
the distance from the triangle plane in the normal direction. Just
set it to zero and you should be fine. The above can be converted to
Softimage Matrix types pretty easily. Probably could be added to the
Softimage SDK as well if it isn't already there.

RE: Maths problem (barycentric coordinates)
Translated from the Greek: 1. Calculate the distance from the test position to each of your selected points. 2. If one of the distances is 0, stop. The corresponding coordinate is 1, the others are 0. 3. Otherwise for each of the distances, calculate 1/distance, or 1/distance^2, or 1/distance^3, or ... . 4. Normalize the values above. In other words, get their sum and for each value calculate value/sum.

Re: set data
I'm not 100% sure I understand what you're trying to do, but if it's of any use evaluating and fetching data are completely different things. You can almost always rely on data for checks (I say almost becuase it's even TOO reliable as it lets you use things before you set them, which is a nice trick with arrays, but some times bites), evaluation though is strongly rule driven and you have to think of it as non-transparent, or at least non-manipulatable. You simply can't rely on checking if something will be evaluated a certain way or not, because evaluation itself comes before you could get a result. It'd be different if you had some of the classic parallel programming devices available (barriers, traffic lights, forceful eval ordering and so on), but ICE tries hard to maximize performance while exempting the user from dealing with those details actually.

Re: ICE - Get closest location on group
so you are saying that: sphere prop named A neighbors props named B and in your icetree: Closest location -- A is still working? that might be a refresh issue, can you try to cut/paste the whole tree? --- Ahmidou Lyazidi Director | TD | CG artist http://vimeo.com/ahmidou/videos http://www.cappuccino-films.com 2013/7/18 Matt Lind ml...@carbinestudios.com I renamed all the neighbors' clusters and the ICE Tree still worked. That's why I was confused.

RE: ICE - Get closest location on group
all objects started with the same cluster and cluster property names: sphere.cls.NC_VertexData.PrimaryColor grid.cls.NC_VertexData.PrimaryColor torus.cls.NC_VertexData.PrimaryColor cube.cls.NC_VertexData.PrimaryColor I renamed the neighbors so all are unique: sphere.cls.NC_VertexData.PrimaryColor grid.cls.ralph.PrimaryColor torus.cls.joe.PrimaryColor cube.cls.harry.PrimaryColor After this modification I disconnected and reconnected the ICE tree, but the ICE tree still worked.
