Re: ICE Internal Cache

[Eric Thivierge]

Just updated the gist and marked the attribute as 'AlwaysEvaluated'. This
is important to ensure it sticks around. Also worth checking out the
AddStaticICEAttribute() command too.

Sometimes it's tricky to just freeze a mesh that has an ICE Attribute on it
that is driven to "store" it. Next time you open / save the scene Softimage
could clear that data since it's not being used. I've had that a few times
unless you mark it as AlwaysEvaluated in the ICE Attribute Editor.

 pretty sure you could:

 Get PointPosition => Build Array From Set => Set Data (self.myDataArray
 {or whatever name you choose})

 Then use a Get Data node referencing "self.myDataArray" if in the same
 ICEtree, or referencing the geo or pointcloud you set the data on if
 applying to other geo.

 I think it needs to get more complex if you're building the
 pointPosition array from a pointcloud that has a varying number of points,
 like a sim in which particles are being created or deleted...

Re: ICE Internal Cache

[Busty kelp]

I haven't looked at Eric's file, but if you want to, this is very easy in ice. 
You can store per point data adding each frame to an array. On a clone.   At 
the end, freeze the clone and it will be a Permanent attribute you can read 
from another object.

Re: ICE Internal Cache

[Eric Thivierge]

Yes I've done it for an internal tool. I can dig up a snippet in the next
few days. You're basically going to write to a Vec3 array attribute that
you'll have to pre-fill with place holder data then build up your data
array through your timeline pass and at the end set it all at once.

It's essentially emulating the shape plot feature where it baked the data
to a clip internally to the scene. So you don't have to manage this out of
the scene.

Re: ICE Internal Cache

[Ed Manning]

pretty sure you could:

Get PointPosition => Build Array From Set => Set Data (self.myDataArray {or
whatever name you choose})

Then use a Get Data node referencing "self.myDataArray" if in the same
ICEtree, or referencing the geo or pointcloud you set the data on if
applying to other geo.

I think it needs to get more complex if you're building the pointPosition
array from a pointcloud that has a varying number of points, like a sim in
which particles are being created or deleted...

Re: ICE Internal Cache

[Bradley Gabe]

Any reason you don't want to save to an external file? I used to create
point clouds just to store specific data sets to then use to drive another
simulation. For example, creating a volumetric cloud of vectors you could
visualize to drive another simulation.

ICE Internal Cache

[Jeremie Passerin]

Hey guys,

I'm not sure if there is many people left on that list to answer, but I
thought I'll give it a shot.

I was wondering if there is a way with ICE to cache point position per
frame internaly without saving to file.
I'm thinking maybe I could build an array of point position, and then read
from that... not sure how to do that though.

Any idea ?

Thanks,
Jeremie
