 those 2.5s are from the scatter node.

It is indeed pretty fast, 5.1s including scatter. Without the scatter is
2.0s

Re: Multiple objects copy

[Olivier Jeannel]

ok thank you, we have the same scene.
On my old workstation I get a 31 s result, while on my recent laptop I have
13s.
I tried the "supermulticopy" setup I sent (I replaced the delete nodes with
some blast nodes (grabed 0.5 to 1sec) and on my laptop I'm doing 3.5s with
350Kpoints for 10 distributed objects (his doesn't include the scatter, but
include  a noise though)

So my workstation is good for the bin...

 I opened his scene, upped the number of points to 350 000 , opened a
 performance Monitor, hit record and turned the blue (display/render) on.
 I red 32.4s on the Total Statistic. (it varies a bit, between 34s and
 30s) And this doesn't include the scatter computation.
 My machine is a dual xeon of 2013 or 2014 at 2*6 core at 2.3Ghz 64GB
 ram. Not the most recent maybe ?

Re: Multiple objects copy

[Oscar Juarez]

I did a simple test with the compiled bock, I'm copying 5 packed primitives
to 100,000  points, performance monitor gives me 3.1s on an i7, 4 core @
3.6 with HT, I noticed that if you visualize any node inside the compiled
block, the cooking time is longer. Also measuring the with compiled blocks
on the performance editor should only show the compiled block nodes, it
doesn't any node inside of them.

Re: Multiple objects copy

[Olivier Jeannel]

We're not talking about "Packed Disk Primitive" right ? just plain packed
prim.
I opened his scene, upped the number of points to 350 000 , opened a
performance Monitor, hit record and turned the blue (display/render) on.
I red 32.4s on the Total Statistic. (it varies a bit, between 34s and 30s)
And this doesn't include the scatter computation.
My machine is a dual xeon of 2013 or 2014 at 2*6 core at 2.3Ghz 64GB ram.
Not the most recent maybe ?
Am I totally off ?

I haven't, but I've done other very similar setups with compiled foreach
block and found the performance to be fantastic.

 Kind of rooky question that I already asked but...

 So I have that "problem" with the copy sop (copy to point,
 whatever) when I have to do a copy with multiple input objects.
 It was something really easy within ice with high performances.

 I watched the sidefx tutorial, and so far I undertstood they
 deprecated the stamp method for a copy within a loop.It's rather slow.

 I also saw a method where it copies all the multiple objects on
 each point and then delete according to the ptnum the undesired 
 copies. it
 gets very slow when you have many different objects to copy and it eats
 memory.

 So I made my "own" method
 The scenario was
 working with packed
 10 different objects(platonic, torus, sphere, etc)
 I have some scattered point
 I have a noise (float) on the scattered points
 I want to distribute my 10 objects according to the values of that
 noise

 so I divided my noise in 10 zones (based on grey float values)
 I counted howmany of each object there was per zone(@numbperzone)
 I copied each object the good amount
 I placed each copy at its corresponding scattered point

 et voilà

 now for 10 objects distributed on 35 points it takes under 10s.

 Nice read. I'll try to replicate the last setup to compare specs.
 I really wonder how much a compile block speeds up the computation.

 So I have that "problem" with the copy sop (copy to point, whatever)
 when I have to do a copy with multiple input objects.
 It was something really easy within ice with high performances.

 I watched the sidefx tutorial, and so far I undertstood they deprecated
 the stamp method for a copy within a loop.It's rather slow.

 I also saw a method where it copies all the multiple objects on each
 point and then delete according to the ptnum the undesired copies. it gets
 very slow when you have many different objects to copy and it eats memory.

 So I made my "own" method
 The scenario was
 working with packed
 10 different objects(platonic, torus, sphere, etc)
 I have some scattered point
 I have a noise (float) on the scattered points
 I want to distribute my 10 objects according to the values of that noise

 so I divided my noise in 10 zones (based on grey float values)
 I counted howmany of each object there was per zone(@numbperzone)
 I copied each object the good amount
 I placed each copy at its corresponding scattered point

 et voilà

 now for 10 objects distributed on 35 points it takes under 10s.
 https://urldefense.proofpoint.com/v2/url?u=https-3A__drive.google.com_open-3Fid-3D0B1QqhXD7Y15qVnBqMVhKeWl0dnc=DwIFaQ=76Q6Tcqc-t2x0ciWn7KFdCiqt6IQ7a_IF9uzNzd_2pA=GmX_32eCLYPFLJ529RohsPjjNVwo9P0jVMsrMw7PFsA=k8MCxZEChDRtBGvXdCRk_HmdVGK1a30LXgOQGyhTYgI=6EPPq-cyeVsxce5iw5TO_anr6T52RUXppsKCPhLx0GA=
  
 

 That's my best method for now, but I have now idea if it's worth
 something.

 So how do you guys usually do ?

Re: Multiple objects copy

Mmm, unless I made a mistake replicating his copy + switch + compile, I'm
getting a rough 33s to copy 10 object other 35 points.

I know you know for instances, if it's about closer equivalent
to ICE. ICE use instances, not ''real" copies. Expression to
spread multiple objects by Houdini instancer, I think it was
(in times of H 14) something like
../../instobj`$myid`
where instance candidates are named instobj1, instobj2 an so
on, while "myid" is an integer attribute on points-carriers
(created in any way you want).

Now back to "real copy"  - I've noticed that in some cases,
it's significantly faster to use a plain Copy SOP, making a
lot of ''in place" copies, then to move their points by Point
VOP or something. "In some cases" seems to be everything
except Line primitive (that's again from H 14). There seems to
be a big difference in working of 'plain' Duplicate SOP and
Copy to points SOP, anyway.
So in that way, first step is merge of all instancing
candidates, then Connectivity SOP to assign class attribute to
each piece (that Connectivity method will work only if one
candidate = one island, obviously). After that, Point
VOP/Wrangle to save the number of points, let's call it
nbinitial attribute. Then, plain Duplicate SOP without any
transform, to reach final number of instances. Finally, in
distributing Point VOP, decoding is something like : point
number converted to float, divided by nbinitialand floored.
Result is then multiplied by number of candidates, to get
proper spread and empty space for individual objects. Class
attribute is just added to result, to fill that ''empty
space". Final result is point number for importing the point
attributes from Scatter Sop or like.
While it is  a bit complicated, method is quite fast, easy to
repeat, and it allows any kind of  deformation on each
"instance'', before-after spreading. With some playing by
expressions and custom parameters, no big deal to sync the
numbers on emitter and copies.

Kind of rooky question that I already asked but...

So I have that "problem" with the copy sop (copy to point,
whatever) when I have to do a copy with multiple input objects.
It was something really easy within ice with high performances.

I watched the sidefx tutorial, and so far I undertstood they
deprecated the stamp method for a copy within a loop.It's
rather slow.

I also saw a method where it copies all the multiple objects
on each point and then delete according to the ptnum the
undesired copies. it gets very slow when you have many
different objects to copy and it eats memory.

So I made my "own" method
The scenario was
working with packed
10 different objects(platonic, torus, sphere, etc)
I have some scattered point
I have a noise (float) on the scattered points
I want to distribute my 10 objects according to the values of
that noise

so I divided my noise in 10 zones (based on grey float values)
I counted howmany of each object there was per zone(@numbperzone)
I copied each object the good amount
I placed each copy at its corresponding scattered point

et voilà

now for 10 objects distributed on 35 points it takes under
10s.

Multiple objects copy

[Olivier Jeannel]

Kind of rooky question that I already asked but...

So I have that "problem" with the copy sop (copy to point, whatever) when I
have to do a copy with multiple input objects.
It was something really easy within ice with high performances.

I watched the sidefx tutorial, and so far I undertstood they deprecated the
stamp method for a copy within a loop.It's rather slow.

I also saw a method where it copies all the multiple objects on each point
and then delete according to the ptnum the undesired copies. it gets very
slow when you have many different objects to copy and it eats memory.

So I made my "own" method
The scenario was
working with packed
10 different objects(platonic, torus, sphere, etc)
I have some scattered point
I have a noise (float) on the scattered points
I want to distribute my 10 objects according to the values of that noise

so I divided my noise in 10 zones (based on grey float values)
I counted howmany of each object there was per zone(@numbperzone)
I copied each object the good amount
I placed each copy at its corresponding scattered point

et voilà

now for 10 objects distributed on 35 points it takes under 10s.

That's my best method for now, but I have now idea if it's worth something.

So how do you guys usually do ?
