Re: Static Turbulence
assuming you used “turbulize mesh” – if you go inside the compound, and then inside the “turbulize around value” compound – you’ll see a “turbulence” node. That’s the one giving you the turbulence. You’ll see there is a “get_particle_position“ going into an “add” node, that goes into the turbulence. So simply put, the turbulence value is dependent on the point’s position in space. So it’s perfectly normal on a deforming mesh, that the turbulence values are not the same each frame – resulting in the “swimming” you describe. (I reproduced it by putting two ice trees, each with turbulize mesh – the second turbulize is swimming. If your object is a regular horizontal grid, with only vertical deformation the solution is very simple: after the add you can put a multiply, with the vector set to 1,0,1. This way the turbulence value is generated as if it were a flat grid, hence no swimming. If the base object and/or deformation are more complex, you can set_data the position on the first frame to a custom vector, and use that for the rest of the timeline going into the turbulence - instead of the “get_particle_position”. That way the turbulence is spatially coherent while sticking on the deforming mesh. Wether or not it will “look right” is another question. From: Byron Nash Sent: Tuesday, December 10, 2013 11:18 PM To: softimage@listproc.autodesk.com Subject: Re: Static Turbulence Yes, it wasn't that. The issue was my ground was moving around and ended up getting different turbulence values as it moved through space. Maybe it's a result of the FBX cache? I think I found a way to fix it, however un-elegant. I made a copy of the original and froze it. Created an ice tree to calculate the turbulence offset and stored it. Then in the animated version added that offset value to the mesh. Seems to work.

I need to add some high frequency noise to it and send it back. My first pass has nice noise with a quick turbulence node but it sort of swims as the mesh moves through space. I'd like to set my offset on the first frame for the noise and then have it be the same throughout the sequence. I tried piping the turbulence into a custom set data node and then in another ICE tree read that data and move the points accordingly. It seems like it's still swimming.

SI2012 crash on scene close: access violation in dsprsr.dll
Hey list, We have many Softimage 2012 crashes, even with very simple scenes. The debugger identified dsprsr.dll as where an access violation happens, so I copied the same file from newer Softimage versions and with 2013 or later it works. So the question is, will it be safe to use this newer DLL or is it a bad idea?

Re: can you generate an object anywhere you want?
On the docs it tells you this command *uses output arguments* and *returns an ISIVTCollection which you can use to get the output arguments*. What this means is you can do: var dr_obj = ExtractFromComponents(ExtractPolygonsOp, , detachName, true, siImmediateOperation, siKeepGenOpInputs, null)(OutputObjs)(0) The (0) bit is because (OutputObjs) returns a collection, but if you're only doing this for 1 mesh, it'll be just 1 object, thus (0) gets the first and only item in it.

Pointer for Cage Deformer Logic/Implementation
Hi All, Very soon, I am starting on my own generic custom cage deformer. A mix of C++/Cython/Python. I am thinking of implementing fast calculations on barycentric coordinates with affine transformations. I have some good papers (in my treasure trove but haven't checked it yet). Anyone suggest a different approach other than barycentring coordinates. The reason I will be writing this is for (proof of concept / prototype for now) is to be able to get point cache data from a low res geometry and then use this outside of an DCC to convert to high res deformations. This ways existing animation pipelines which have to rely on switching to higher resolutions before caching out do not have to do so. Simply export out point caches (alembic, pc2, mdd, bgeo, icecache etc.) and then apply this to a high res point data outside of any DCC as post process, even on farms from command line for example. --
Re: Pointer for Cage Deformer Logic/Implementation
My knowledge is out of date, but off the top of my head Cage deformers are often written using a cubic interpolant rather than affine ones. If you use a grid cage you can use Bezier Volumes, which are just a generalization of https://en.wikipedia.org/wiki/B%C3%A9zier_surface. If you are using a regular grid, you can just take 3D coordinates relative to each grid. If you use a tetrahedral mesh, you can use generalization of the Cubic Triangle for deformation: https://en.wikipedia.org/wiki/B%C3%A9zier_triangle and then you need to use barycentric coordinates to get a relative spatial relationship. So I think yes, barycentric coordinates within a space filling discretization of space, either a grid or a tetrahedralization with a cubic interpolate as you start to deform them. I implemented the grid-based deformation with cubic volumes and got this result: http://www.exocortex.org/ben_software/hd-ffd.zip I have also implemented the tetrahedral-based discretization with Christopher Batty to deform a high resolution object to follow the path of a low resolution object to really good success. The only issue is that tetrahedral meshes suck to create and maintain efficiently. It is the bunny getting crushed in the gears at the end of this video -- the actual simulation bunny was super low res, but we uprezed it for rendering: http://vimeo.com/874168 Best regards, -ben On Wed, Dec 11, 2013 at 5:09 PM, Alok Gandhi alok.gandhi2...@gmail.comwrote: Hi All, Very soon, I am starting on my own generic custom cage deformer.

Re: OT FYI Mark Schonnagal will be presenting at the Maya User Group in NYC tonight
Wow that was a great presentation. I actually learned some new ice tricks that I didnt know. I also got a better idea on some of the workflows of getting ice into Maya. There will be a new webinar on it soon. On Wed, Dec 11, 2013 at 12:32 PM, Emilio Hernandez emi...@e-roja.comwrote: Ohhh. Ok thx for the clarification. Well that is good news then!
