Hi, do you think you could do some more videos on Armory 3D? Recently it got Blender 2.93 support and I think it has happened quite a lot since you last visited it. I think the engine deserves more attention than its getting currently, its close to a fully blown engine comparable to Untiy & Unreal at this point

Both magica voxel and csg works well under wine on my machime

Good to know !!!

Some good introduction stuff to SDF's technicals are Valve's paper on sharp decal textures, and Iquilezles's article page.

That is awesome. This reminds me of how simple 3d modeling used to be back in the day. I can see this becoming the go-to tool for novice modelers who just need to make simple shapes. I hope he adds some measurement features to allow for making simple cad models for cnc and 3d printing.

Exactly what I thought, I would love to use this for making and modifying my 3D printing stuff!

I have dabbled with Signed Distance Functions (SDFs) myself and it looks like this guy is doing something I was thinking of, only much better. Good to see and I hope this project will be open sourced. The reason that there is no exporting of generated shapes to a mesh to import the into something like blender is that SDFs only exist as a mathematical model that a SDF rendering engine will display, and do not have anything like vertices or points to define the image seen on screen. SDFs are also highly computational involved, and as such, are rendered purely using a GPU with a fragment shader being the prime source of where and/or the code exists to render the end image being displayed. The best idea I have come up with to generate a SDFs as some kind of mesh model is to generate and save the resultant SDF shapes as a point cloud, and from that point cloud generate a mesh. But this will then require the SDF rendering to be CPU based and not GPU, thus making any generation slow, and for any high resolution, the saved files would be very large.

This is cool. I was looking for SDF modeler for some time. So I'm glad it's finally here and even from a talended MV developer.

¡Uooo, it's exactly (and I mean EXACTLY) the Dreams modeler, but for PC! ¡Finally! This way of modelling is so different to traditional vertices and polys, but once you get to understand it, it's great. Not a technical person, but it's amazing how this system can handle hundreds of boolean operations with no sttutering. And the way this system handles the ¿fusion? ¿soft blend? don't know the term, of hard shapes gives beautiful results with minimum effort. The layers are, most probably, a way of separating different sculptures. Like, say, a head and a hat. And ephtracy deserves some kind of Really You're Great Thanks A Lot award.

This sounds like a really great tool when coupled with some sculpting software.

true, it's also how unreal does prebaked soft shadows by prebaking the SDF for each object in the scene. It's actually really simple and has many applications

So exciting! I just uploaded som videos of me Magicavoxel and was wondering if we’d ever get an update. Boom, found your vid. Stoked.

ephtracy gets a 10 out of 10 for tool democratization - really exciting to see this new project! Going to do another donation to him. Like many others, I can't wait for export features / support for the 'mcsg' file format in other tools (like magicavoxel and its .vox file format). note - I could not see the models until I switched the gpu used for the application to my nvidia card.

Obviously without export options or documentation its not of much use right now, but theres a really solid base here and I think will certainly become a mainstay of 3d modelling tools when its had some time to mature, just like MagicaVoxel.

I just fired it up in Wine 5.0 on Ubuntu 20.04 with an i5-8259U using Iris 655 graphics and was able to make a quick space ship, render it, save it. It is running wonderfully at 1080p and I already love this editor! Can't wait to actually export a model.

This has tremendous potential ! the four features that would make it use every day : - full linux support. - export to dae/obj - basic rigging ( not mandatory but would be cool) - CAD-like features like 2D plan, synchronisation of strokes and patterns. especially that last one would make it the best tool to model weapons, vehicules, etc...

To whom it may concern, much like MagicaVoxels, MagicaCSG also runs fine under Wine/Proton, even in a ten year old machine with a GTS650.

Looks fun! And interesting!

Will certainly be very useful with mesh export. Blender's boolean and remeshing can be very slow/undesirable for complex models.

so cool bro thx for doing what u do

very cool this type of modeling is what I do a lot when I model in Cinema 4D from time to time. However, SDF modeling like this is not great for everything, the use of voxels means that you have to work at high resolutions to get clean results. And that kills performance when not optimized correctly. Pretty excited to see where this goes, probably won't move me away from straight poly booleans tho.

Reminds me of Organica3D. Very cool. :)

Exciting stuff!

Nice! An SDF modeler? That's freaking awesome. -- Lack of export makes sense for 0.0.0, I don't know any standard file formats that support SDF models (obj definitely can't without compiling it into triangles first; but SDF compilers do exist).

SDF can be exported directly as a fragment shader (see curv3d.org). Or you can mesh it using marching cubes or dual contouring (see libfive.org). But it looks like MagicaCSG is using some sort of sampling rendering algorithm. See github.com/mkeeter/mpr.

It is possible to save the render image by pressing the camera button below the render window. But no obj-export

Distance field is distance from something. Signed distance field is distance from something and distance inside of something so the other direction.

Did you try clicking on the drop-down in the Save list to change the file type? Maybe it's got obj in there?

Great program! Would be more useful, if it had an animation tool, like for making sprites. Or a way to import these shapes in a game engine.

This software looks cool.

Reminds me of booleean operations in Truespace.

SDF can be rendered using ray marching for infinite resolution :)

Looks promising, I think this is ray matching technique that's cool because it has similar concepts of kit bashing if it does support sculpting the easy mode I'm all in . this should be stage 2 of none experienced artist . after photogrammetry stage . I think there's similar tool for unity in the assets store but I'm not sure how much they they are differ

PERFECT!!!

In my knowledge SDF rendering is basically 'rule to screen pixels by ray marching shader', so I will surprise to know how to reinterpret the raycasts to polygons.

Since this is OpenGL-based, could something like GLIntercept or OGLE be utilised to effectively export/save the resulting geometry?

It says no export options right now directly on the download page :P Cool software though, can't wait till it convert to obj or something so we can play around with them in unity etc.

This "voxel wrapper" is how sculpting in 3D-Coat has worked for over a decade.

This looks really cools for hard surface modelling. Needs exporting though.

Dude it's just like dreams!!

Power Up! Great News.

Helped my son do a CSci senior project on signed distance field rendering. The barrier for an exporter is there is no polygonal mesh for SDF objects (objects are defined by mathematical function, not vertices). You can certainly calculate one, similar to Blender’s remesh tools. But like remesh, it will lose precision and won’t have great topology.

@@n.lwhitaker572 Sort of. It’s not a perfect analogy. More accurately, voxels are the analog of bitmap pixels in 3D. The difference between SDFs and polygonal modeling is more like Bézier curves vs. straight lines, or painting vs. a mosaic, or literally the mathematical function for a circle vs. lines connecting a finite number of points along that function. Additionally, polygonal modeling defines the surface zero-thickness skin of an object, where a SDF calculates interior vs. exterior points in space, lending itself to constructive solid geometry (CSG) because by definition you can’t end-up with non-manifold [impossible in real space] shapes, like you can with polygonal models.

Amazing

Could be usefull for hard surface modeling

So, can we make a game engine that directly renders a SDF? Or would it be too slow for real time?

I could be wrong but I imagine the reason there's no export is because the model typology would be an absolute mess.

It's not working on my pc is there any solution

cool stuff but doesn't work on my 1050 laptop... I cant see the model.

Correct me if I'm wrong, but you can't export an SDF model because there are no vertices that define a 3D model to begin with. Unless there's a way to wrap vertices around an SDF model

there are many, many ways to do it. Almost all remeshing tools convert meshes to volumes as part of the remeshing process

But this is a voxel renderer just with smoothing via SDF?

Damn damn this is nice

Version 0.0.0?

Just playing around with it and it's intuitive and fun. However, it sorely needs export functionality. Also, he should seriously consider porting to iPadOS. The new iPad Pro and M1 chip are made for this.

This is freaking good! Time to say bye to magicavoxel for some time.

If all you can do is mess with it in the program what exactly is the point of it?

@Gamefromscratch the reason there is no export is most probably because the "objects" never technically exist... (at least not in triangular mesh form). It's very common to just do the rendering (including the viewports) using ray-marching, sampling the SDFs directly, without ever "meshing" them. So meshes can't be exported because they never even exist in the first place. Meshing a compound SDF is non-trivial - even more so than voxels. Not impossible, just very complicated. I suppose one way would be to first voxelize it all at very high resolution, then mesh the resulting voxels. But really, meshing would be defeating the purpose. Especially for film. Every offline renderer could easily support rendering SDFs, and that's like SVG for triangles - it keeps it all vectorized all the way, so you get unlimited resolution very cheaply with tiny memory footprint by comparison to triangulated meshes. For games, nowadays you could argue the same, especially with the rise of realtime raytracing.

@orsonpeters

> Meshing a compound SDF is non-trivial Not really, at least not computationally. All these SDF primitives are differentiable, as are the meta-operators (union, difference, etc). Using automatic differentiation you can thus calculate the partial derivatives of the entire SDF w.r.t. each coordinate. This is used to compute the surface normals (although numeric differentiation is also used). Since the SDF is differentiable you can use gradient descent to find zeros very rapidly. And the zeros of the SDF are exactly the surface you're trying to mesh.

@AinurEru

@@orsonpeters Unless you consider partial differentiation "trivial", it kinda supports what I said :) Even then, saying it's trivial to describing a surface mathematically, is not the same as saying it's trivial to mesh it. You still need a "good" story for constructing a triangular mesh out of that description (with varying definitions of "good" there).
