Re: OT Houdini build Array VOP question (and a bit of rant)

ject: Re: OT Houdini build Array VOP question (and a bit of rant) You can think of each geometry attribute as an array which length equals the number of points (if dealing with points). VOPs simply iterate over these points and process the graph for each of them. Since each attribute is an array,

Re: OT Houdini build Array VOP question (and a bit of rant)

No, no you're not mis-understanding. Probably me doing it wrong I will try that too, thank you for making that clear :) All that "thinking" is because I had this project https://vimeo.com/155960784 It's a bit complicate to describe in words. To achieve the rotation per primitive I had to define

Re: OT Houdini build Array VOP question (and a bit of rant)

Maybe I'm misunderstanding but if you already know which point you want an attribute value of, then why would you want to store the values for every point in an array? That'd be a lot of processing for nothing. No need to iterate with a for loop neither. In VOP there's the `Get Attribute VOP` node

Re: OT Houdini build Array VOP question (and a bit of rant)

Thank you so much for your time, explanations and examples Christopher. I'm taking those picture and will reproduce them :) Well, I wanted an array because I need to see if I could be able to retrieve the second element of an array (Ptnum =1 ) using Get Element (I guess). On Wed, Mar 2, 2016

Re: OT Houdini build Array VOP question (and a bit of rant)

Basically, arrays are a convenient structure to pass data around (and to potentially make your code more readable, which won't apply to VOP). If all you need is to perform a computation in place and directly use the result in your VOP graph, then iterating over your points is all it takes—no array

Re: OT Houdini build Array VOP question (and a bit of rant)

Yes I saw it, sorry, I thought there was another additionnal method with For Loop : "Instead, you should be able to just loop over each point with a `For Loop VOP` and do your computation directly in there" Have I misunderstood ? You're doing a for-loop without building an array in the end. On

I did attach a screenshot in my previous email, are you not seeing anything? Or are you asking for the H13 for loop? On 2 March 2016 at 21:20, Olivier Jeannel wrote: > Ah THANK YOU ! > > I'm "aware" of the PCOpen+PcFilter to gather infos based on distance. > I also

Re: OT Houdini build Array VOP question (and a bit of rant)

It seems like they've extended the support for arrays in H14, which makes it now possible to use them as geometry attributes. In the previous versions I guess that there was no real point (but convenience) in creating arrays in VOP since you couldn't pass them downstream with the geometry data.

Re: OT Houdini build Array VOP question (and a bit of rant)

Ah THANK YOU ! I'm "aware" of the PCOpen+PcFilter to gather infos based on distance. I also use the PrimUV a bit and XYZ+PrimUV for location things. I'd be curious on the For Loop Vop, if you have any pictures :/ Sorry to ask. It's a shame there's no tutorial or phylosophycal explanations

OT Houdini build Array VOP question (and a bit of rant)

Hello serious list :) I'm a bit confused with houdini vop array. While I managed to do it in vex, I would like to make a build array (like build array from set) of the pointposition (P) in VOP. I understand you need to for-loop on each Ptnum and probably append the P values and this will buid an
