bizarre behavior while resampling a curve Sept. 25, 2022, 3:33 p.m.

Hi,

This is floating point precision issue. Your best bet is to move the geo to origin, resample, and then move it back.

This will at least alleviate floating precision issues in Resample SOP. It seems like Resample SOP also doesn't work in 64bit precision.

But once you move your geometry far away from origin, expect it to look garbled again. At least this time the data will be correct, it's just the visualization of it can be wrong.

Because the viewport in Houdini is also not 64bit.

Repeat For-Each Loops with further For-Each Loops Sept. 25, 2022, 3:19 p.m.

Hi,

If you want to do that, the entire section above where you want randomization needs to be embedded in the last for each loop network.

You can't send out random values out of a loop to the nodes above it like that.

Back in the day there was some old workflows like that but they were more like hacks for feedback loops.

Thanks for the link and the example file @gorrod!
I was afraid openCL was going to be the answer here.. Guess it's time to get my feet wet with it
Thanks!

You can do this in VEX also. You are using detail attribute functions on a volume. If you want to do the equivalent operation on volumes, have a look at the Volume Reduce SOP.
