Technical Discussion » Houdini support for Parquet format

A lot of analytical workloads these days rely on Parquet format. Support for it might open Houdini for example for data visualization tasks. Was wondering if there have been any previous attempts in this area?

Technical Discussion » Distributed SOP cooks?

Thanks for the replies. Yes, I realized that the reason DOPs need their own distributed solution is because the slices need to COMMUNICATE with each other in the runtime. They also need to run in lockstep. I'm sure there are plenty of other reasons, as well.
But, but - I think that it still would be great if the SOP geometries could be easily sliced and distributed in one nifty node. Maybe that's an idea for another day. There was a GameDevTools once - maybe it's time for SciDevTools now
I think that this problem must have been documented somewhere else - surely various games must have come across it, it's not too different from multithreading. I mean what problems come up when distributing stateless geometry processing tasks.

The video [www.youtube.com] showcasing distributed particle sims has been around since 2015, but only recently it occurred to me that this technique only applies to DOPs?
Am I correct in saying that there is no general solution to distribute SOP cooks? For example, slicing and aggregating (map-reducing) VDB clouds or any VEX snippets on large meshes?

cat data.csv | houdini script.{hip,hda} > new-data.csv
I call it... HOUNIX
It would be great if one could use houdini hips/hdas as general tools for processing datasets. In the above example this might be a csv file.
The question is how though?

For example, adjusting parameters on the nodes. I found both the scene and graph panes to be useful on certain occasions. Potentially a solution would be to create a network tab on the same pane as the scene view and CTRL+TAB into it. But then you can't see how changes affect the scene.

Can you switch focus to network graph regardless where your mouse pointer is currently located? It would be great if you could for example do something in the viewport, quickly ctrl+tab into network graph (on another pane not tab), do something and switch back to the viewport.

Technical Discussion » Vex vcc on Godbolt

It would be amazing if we could peek into instructions/assembly that VEX produces. There wasn't any other language that got me this close to hardware on a regular basis as Vex, so to be able to see intrinsics (at any given time) would be a blessing.
Could it be done with other disassemblers? But just from the user's perspective, Godbolt [godbolt.org] is such a successful tool.

fair enough, there is "data wrangling" as well, but I guess then that's from a different herd

Given that large portion of names in Houdini and especially in VEX (bindings, intrinsics...) have equivalents in low level programming I was wondering about the origins of the wrangle nodes.

s88ngHave you looked into the OpenCL node? It lets you write and run "kernels" on GPU (and other devices). It came in handy once, when I had to "grow" selection of points on a large point cloud.
Imagine VOPs running on shaders in SOP
What else, in all fairness I'm team UE when it comes to comparisons with Unity, because Epic Games didn't settle for C#, but thread the good ol' C++ way. Didn't bring this up, because it's not as easy to pick up as Houdini's VOPs, but I imagine that a lot of optimization could be done there.

s88ngyeah, I really should have put more effort into explaining this question. True and honestly I can't wait for UE5 release. Level of detail on their demo was mind-bobbling.

s88ngI mean UE looks nice, UE5 just amazing, but "scripting" in UE is more optimized for flexibility not performance, I mean not even close Hou

Technical Discussion » Transfer a multidimensional array to Houdini (from Java app)
- dankray
- 82 posts
- Offline
I am experimenting with an interesting program [bitbucket.org] written in Processing (Java), which generates a large three-dimensional array. What would be an efficient way to import it to Houdini?
It doesn't need to be saved to disk. Actually come to think of it I would like to know how to share program data like this (a 3D array) with Houdini. Where in HDK could I find a hint?
Saving it to a csv file and importing this with a sorry python import node was... not ideal.
In other words how to share memory with Houdini?

fair enough, I should have qualified my question - I'm interested in Houdini's performance in geometry modeling to 'proceduralize' some of the tasks that would bog down other, less performant programs. I realize that VFX pipeline is crazy complicated and Houdini isn't the pinnacle for compositing, polymodeling and others, but when it comes to SOPS... man, it's so good (is my impression).

MidphaseAll valid points. I was mostly referring to SOPs as this is what I am using most often in Houdini. Geometry modeling in Houdini is that pinnacle I was referring to. My impression was that the way it represents model data is unprecedently tuned for performance.

Librarianoh wow, haven't heard that one before. Was it 'softimaged' by Microsoft? Shame...

I'm under impression that Houdini is the pinnacle of achievement when it comes to performance. Is there any other software that comes to your mind that performs as well as Houdini or at least comes close to it? I imagine that even scientific simulations in Fortran wouldn't be as fast.
