Add Point & Repeat node

[rray]

ICE noob here with a question, I know it's generally bad style and I could plug an array of 5 vectors into the positions of Add_Point, but why doesn't this graph here generate 5 points as well?

Plugging 5 Add_Points into the main node does that.

Thanks

I don't know why, but this way it works

Plug a Set Data into the On Creation and do something, anything. Like set self.size = 0.
Then you get more points.

I guess ICE thinks you're not really serious about it otherwise.

Seriously though, I don't know why, but it looks like ICE is being too agressive about optimizing things when Add Point is not in the Simulation stack?

First steps to ICE's self awareness? Cheers mates, both methods work great, so it's an optimization thing.

This will be my new signature

Wait until you get to the cache on file node. That's an overly zealous little beast...

What is going on?

I used to be an ICE user like you, but then I took a context mismatch in a tree

If you think you had a problem with this one, how about repeat nodes on two arrays of 1.03 million indices each. Talk about stress test on your system and I am not finished! Time to optimize and think outside the box before I lose track of things!

Seriously, ICE is fun, welcome to the group and please share your adventure, there are always new ways to hook those little nodes! Warning, it is addictive!

It looks like an over-optimization but I don't think it has to do with Add Point not being in the Simulation stack. I suspect it has to do with ICE thinking that nothing is changing in that branch because there's no Set Data. Add, Clone, Delete Point, etc., should be treated the same as Set Data in that case.

Skynet lol
Daniel - Cheers for the welcome! TBH I've dived into ICE before but always go back to being a noob after a while of having to do regular programming. I guess they don't mix well

For example right now I'm not able to find a way to convert an array like
1 2 1 5 8 7
to
1 3 4 9 17 24 (sums of the array item and all items to its left)
without using a repeat loop and a temporary attribute... somehow feels wrong by ICE philosophy but maybe there's no other way. Would be curious of course if someone knew

Write a custom node to do it, then you can have both ICE and regular programming

You'll have to use the Repeat, unless you do something like a point cloud where each point holds a value, so you can use the data set...see here.
