Since several people asked, it's now on GitHub as well: https://github.com/cj-dao/mapped-stereogram-maker

I've also recently added cross-view support per u/DissonantGuile.

Note on development progress

I mainly made this tool for myself since there were no other convenient tools out there at the time. Because I already incorporate photoshop and Blender into my workflow, I didn't feel the need to add extra features like a dedicated depth map studio. I may do these things in the future but for now I wouldn't count on it.

Thus if u/eyefind3d ever releases a version of their software (whether open-source or paid) it will probably be a lot more feature-rich and industry-ready. Although that's entirely their prerogative.

Anyone can fork the repository and make their own additions to the core algorithm if they want to; at this point I have little plans to continue active development unless I notice a bug that directly interferes with my workflow.

On Depth Maps (and my workflow)

I've been using this Blender tutorial for making my depth maps: https://www.youtube.com/watch?v=7_9uS2ixBCs

As EF3D mentioned, if you can create your own outlines in photoshop it will be better than the auto-outline feature on my website. My typical workflow includes taking multiple textures (including a custom-made outline), creating multiple stereograms, and layering them in Affinity (Mac version of photoshop). This allows me to do cool tricks like transparency in the attached photo. For that one I actually used two different depth maps, allowing me to have 3d objects floating inside other objects.

For all of you who want to create your stereograms, I've coded a website that makes mapped-texture stereograms (stereograms where the color/pattern matches the 3D object). I've always wanted to make these, but most other online generators and software either make plain un-mapped stereograms, or are for really old versions of Windows and are quite janky.

I love when artistic tools like Blender are open-sourced, so I finally got the motivation to code it and make it into a website: https://mapped-stereogram-maker.web.app

You'll still need to provide your own texture and depth map, but the website can automatically generate outlines for you if you want some simple texturing, and I've included some example demos.

The website is still very much in development, so expect bugs! I may also make a future post with a tutorial and additional stereogram algorithm info for those interested.

Enjoy!

I haven't seen many realistic lava lamp simulations out there that use actual fluid physics and not just a couple metaballs floating up and down, so I decided to code one myself and use the actual lava lamp that I own as a reference.

Details: SPH Lagrangian simulation with 3000 particles with simplified surface tension, viscosity, pressure, turbulence, etc. Particle physics is done on the CPU, rendered on GPU with fragment shaders.

See the comments if you want to try out the sim / see the source code.
