[Morten Bartholdy]

Oh I didn't think to check the Grid for ICE trees - all cool now and working in
2013 too :)
This list remains a goldmine :)

Thanks guys.

Re: ICE - how to align instances to edges?

I tried rebuilding it in Soft 2013 SP1 (by copy/paste) as I might have to do
this in that version, but the Gg node remains red - is that a 2015 node?

Re: ICE - how to align instances to edges?

[Olivier Jeannel]

"Gg" sorry for the name ^^.
Look into the icetree that is on the "Grid" object. That's the one that
calculate the "tangent" I called "Gg".

To select all edges border :
Select edge mode (right menu)
then select "border edge" in the menu just below.
Now if you rectangle select with the mouse in the view, only the border
edges (the light blue one) will be selected.

Wow thanks a lot Olivier - that looks like it will do the trick. The reason
I didn't want to use curves is merely that I will get a lot of polygon
islands and don't know how to automagically select all border edges for
extraction - otherwise curve tangency would be fine.

The Get Gg node just before Align Particle to Vector looks like it is the
one that provides the edge vector, correct!? But I fail to understand what
it is doing though.

Re: ICE - how to align instances to edges?

[Morten Bartholdy]

Wow thanks a lot Olivier - that looks like it will do the trick. The reason I
didn't want to use curves is merely that I will get a lot of polygon islands and
don't know how to automagically select all border edges for extraction -
otherwise curve tangency would be fine.

The Get Gg node just before Align Particle to Vector looks like it is the one
that provides the edge vector, correct!? But I fail to understand what it is
doing though.

Cheers
Morten

 I am tinkering with a simple method for creating a cityscape in ICE
 using
 scatter tools. Julien Carmagnac SiScatter does most of what I need with
 insetting instances from edges and even scattering, but I am missing one
 important functionality. I need to be able to align the x or z axis of
 the
 instances to the tangent of the closest border edge, and then add a
 little
 randomization to the y rotations. I have looked deep into the compounds
 and
 tried different ways to get the edge tangent, but alas my ICE skills
 come up
 short here. Any scattering tool would do I guess - Milan Vaseks Scatter
 Tools or
 even simple nonsimulated emissions, but I need this extra alignment
 method. I
 tried Juliens Generate instance on Curve too, but it requires edge
 curves to be
 selected and extracted, plus it seems the instances seem to be flipped
 180 deg
 on the y-axis between isntances without any way to control it.

 I have attached a screenshot showing a simple test where the A example
 is what I
 need, and B is what I get with Generate instance on Curve.

 Any ideas on this will be much appreciated.

 Best
 Morten

Re: ICE - how to align instances to edges?

[Olivier Jeannel]

If you don't want to use curve (and curve tangent), I made this, but you
need then to subdivide your edges to get good result.
It calculate a "tangent" stored per point on the polygonal object.
Then your Pointcloud get the closest location and take that tangent data
and aligns vector.

You don't want to work with extracted edge curves ?

Re: ICE - how to align instances to edges?

I think there might be something in Eric Mootz's emTools that does
alignment to edges?
