@ephtracy Did you know this online SDF experiment? It's simple but smooth.

@metin it’s mesh based not sdf based as far as I know.

Decided to start creating something in Womp today, a free online SDF modeler (subscription = more features).

Although MagicaCSG wins in terms of speed, versatility and UI / UX, Womp has got some nice features too.

Updates will follow.

Want to try Womp yourself?

@metin wondering if you can use NURBS tools to model characters or other organic objects

Started a new MagicaCSG SDF modeling project…

What will it become? 🙂

More will follow in this thread.

let's just make it work first #magicaCSG

w.i.p. rewrote a large part of the backend codes to support that. #magicaCSG

@metin need to redesign workflow for operations on hierarchies.

ephtracy,
@ephtracy@mastodon.gamedev.place avatar

@sjb3d yes, I managed to find a way to cull the trees (currently two-level). it’s still very limited though. Compound sdfs definitely have artifacts (especially the interior region). but users may still prefer at least having some ways to localize the boolean operations.

I recently did some work on improving the import/export of emissive materials in Avoyd to/from @ephtracy's .vox format and whilst doing so saw this interesting pattern during rendering.

I've not tried to reverse engineer the MagicaVoxel rendering (Avoyd uses standard unidirectional path tracing), but this has me intrigued as to the algorithm and whether it's been written about anywhere.

Note: voxel emission increases by a factor of 10 each voxel from top (darkest) to bottom (brightest).

@dougbinks the built-in renderer was mainly developed for opengl 3.3 (to be compatible on macos back in 2017). therefore, I have to do some tricks to reduce the workload on the shader side. but it's still an unbiased path tracer (the rendered image will converge with sufficient samples)

SDF is referred to as the "Signed Distance Field". the work is mainly based on the prior R&D work from
@iquilezles, @mmalex, @sjb3d and @lritter, and I'm glad that I also developed some of my own techniques in this program. #magicaCSG

note that unlike cylinder spline, you can use Boolean subtract and groove blend on this capped spline. #magicaCSG

Started a new MagicaCSG 3D scene. As usual, I'll keep you up to date of the progress again.

A coffee is always appreciated. ☕😉

@ephtracy Thanks for the boost, I'm honored. 😊 Feel free to share it elsewhere as well (such as on Twitter).
