I've been playing around with this and having so much fun! Thank you for making this, and keeping it free/opensource. 1 question: how are you assigning/blending the colors from the teaser, for example the torus sinking in to the ground? Is there a way to assign colors to the SDFM primitives so that they retain colors after being converted to a mesh?

@Handcraftedcc 4 ай бұрын

Heyo! Sorry for the delayed response! I assume you were the one that emailed me about this, but just in case I'll respond here too: What looks like colors blending in the teaser is actually just a shader setup, there are no separate colors for the meshes. Now if your meshes are separated you can use the segment option in the volume2mesh node. But if you have shapes combining that won't work. Also not sure if that would be stable in an animation. What you could try is to extract your source shapes using the prim to mesh node (I can't remember the actual name but there's one that will convert your control prims back to a usable mesh), apply color to that and then use a attrib transfer with a blend radius to transfer the colors onto the meshes model. No idea how clean that would look though.

Thanks so much Dominik this rules! I did have a possible feature request - it would be great to get those Prims out as surfaces also ( before a convertline.) Just thinking for moving from the volume to refined hard surface would be good to have them to use as surface prims for hard-edged booleans etc. For instance say I've made an LED display screen, I have used SDFM to make the surround for the acrylic screen (using a box prim (A) to make a negative where the screen would be in SDFM) - if there was access to the surface geo of (A) I could then just have a screen surface geo to use already exactly in place...Hope that made sense...

@Handcraftedcc 10 ай бұрын

That's a great idea! I think the easiest way to do so would be to create a node that converts the prims to surfaces! I'll look into it! :)

Amazing tool, great to have a little sdf toolkit in houdini. I wondered at the beginning of the video, if you could have a hook where we could add custom sdf function and have it as a sdf prim node. With the pig head example i guess that could be done using a volume wrangle or volume vop with an sdf prim node. Would that be efficient ? when you say that the one you propose are more efficient, is it because there are simple primitive like sphere or tube or because you did some specific optimization ?

@Handcraftedcc 10 ай бұрын

I like the idea of custom functions, but I'm not sure that that would be easy or possible to implement without having to rewrite large parts of the toolset!

This is awesome! Dump question though. Is their any possibility of using the normals of an object and including those to shape the SDF when converting from polygons?

@Handcraftedcc 10 ай бұрын

Hmm I don't think there really is, at least not that I'm aware of! Generally if you can subdivide the mesh beforehand that's your best bet. One thing you can in theory do is transfer the normals back from your source mesh after converting the sdf to polygons. That can be finicky though, as you have to mask it to make sure that it won't affect the transitions or other areas that are different from the source mesh.

@BlackPantherElite 10 ай бұрын

Looks great and something I would love to get into. Being a newbie in Houdini - what / how does this SDF toolset differ from already implemented Houdini nodes / features via vdb sdf ?

@Handcraftedcc 8 ай бұрын

Houdini only ships with a very small set of sdf tools that are not tailored for sdf modeling, more for general sdf volume operations. Houdini does not have sdf math primitives nor does it have tools to create the smooth/chamfer transitions etc.

Technically it's already possible (axiom for houdini is gpu powered for example). The issue is that for GPU you need to use opencl instead of vex, which is a very different challenge. Might try to tackle that at some point.

Hi. Congratulations on the video, I don't understand step 3 of the installation. Replace "PATH/TO/PACKAGE/" with the path to the folder. In my case it reads: "C:/Users/Dominik/Documents/Houdini Assets/Project Packs/DomLib" Make sure to use "/" as separator, not "" otherwise it won't work.😅 Where should I edit this string? Thanks

I think it refers to the directory separator, Windows uses "\" but within the Json it should be changed to "/"

@wrvideo_tests 10 ай бұрын

The file you need to edit is the SDFM.json file, and that should be placed in a folder called 'packages' which needs to be somewhere inside your Houdini preferences folder, which is in the top level of your Documents folder, (or Mac equivalent). I use a single packages folder but Houdini does seem to check -any- packages subfolders within the preferences folder structure. There's a Houdini preferences folder for each major version, named after that version, so it'll be houdini19.0 or houdini19.5 etc. You need to set the path in the SDFM.json file to the location of the SDFModeler folder, wherever you've put that. (FWIW, the environment variable for the preferences folder, which is $HOUDINI_USER_PREF_DIR, can be used in the path, and relative paths are supported so something like "$HOUDINI_USER_PREF_DIR/SDFModeler" would work if the plugin folder is dropped directly into the preferences folder, or "$HOUDINI_USER_PREF_DIR/../HoudiniPlugins/SDFModeler" if you had created a single location in your Documents folder -beside-, not in, the Houdini preferences folder, (and called it HoudiniPlugins)

@Handcraftedcc 10 ай бұрын

Yeah, like other said you want to update that in the .json file to point to the downloaded and unzipped folder and put that into your packages folder. If this is your first package, just create one. In windows that is normally documents/houdini19.5/packages.

@YuuJer 10 ай бұрын

is there a way to say, merge 3 things, A B C, where they all overlap, like 3 balls in a triangle, but only A and B blend, and B and C blend, but A and C don't blend? like if you made fingers, but don't want them to blend to other fingers, but just to the palm

@Handcraftedcc 10 ай бұрын

Hmm you cam get to some degree by A: getting the order right. For example if you want the fingers to bot blend with each other but blend all the fingers with the hand, you can first add the fingers together and then add the palm after with your desired blend. B: use sub assemblies. So make an assembly with all your fingers and then merge the second output of that onto the palm. You can see an example of that workflow under the sub assemblies part of the video! That being said beyond those two methods you can't specifically say which part you want to blend with. Hope that answers your question!

any way to run geometry operations on the primitive shapes the SDFs use? seems like a useful idea to get more complex boolean shapes. i know we can use custom geometry but it would be even cooler to quickly tweak one of these primitives as you are building SDF forms.

@Handcraftedcc 10 ай бұрын

Oh gotcha. So the "SDFM Prims" aren't based on polygons, like I describe around 1:33. The shapes you see when you select the SDFM Prim node are just previews of what the underlying math function generates. There is no way to modify those directly. That being said you can always use the SDFM Mesh prim to make custom shapes. Just note that it won't be as performant. @@keithkirby7376

how about texturing those things? how UV map looks for it

@Handcraftedcc 10 ай бұрын

The mesh you get out of sdfs is similar to what you might get when sculpting. So when it comes to UV unwrapping, there is no straight forward answer. You can retopo your mesh, and then uv unwrap nicely. Or you can use autouv or something similar and then paint your mesh manually in substance. Really depends on what you need and what your final goal is!

Is there a reason you used Houdini native volumes instead of Vdb?

@Handcraftedcc 10 ай бұрын

Yes! When doing A/B testing between VDB and Houdini Native Volumes the processing time of VDBs where significantly slower. There were also few to no benefits to be gained in terms of processing time as the vex code seems to also run over non-active voxels. In terms of storage VDBs are more efficient, but it's easy to just convert volumes back to vdbs for storage, however by default this is disabled, as the volumes to vdb conversion also is a hit on performance. The toolset running over big volumes is already heavy enough so I attempted to gain performance by any means necessary! I saw that H20 has made some improvements in terms of vex and vdbs, so it might be worth seeing if that changed anything.

In a way, nTop is obviously much more feature rich and the workflow of nTop is extremely unique. But yes SDF are similar in the general idea. nTop is a very professional software, and this is a 'simple' tool in comparison, so it's only like nTop in that it uses SDFs.
