Any connection this? http://mantawiki.sci.utah.edu/manta/Main_Page

Nope. Just a name collision.

This is a great learning resource for sure, thank you.

Same person who wrote the petrol engine sound simulation, good stuff https://www.youtube.com/watch?v=RKT-sKtR970

Wow that’s amazing

I just stumbled across that video 15 mins before this story. Seems the algos are feeding each other :).

Great, another Fabrice Bellard to make us code monkeys look bad ;)

Is it Windows-only? README only mentions building with Visual Studio

mkl2• 4 years ago

The Getting Started only mentions Visual Studio, but the README only mentions CMake:

This project was recently migrated to CMake and the setup instructions have changed. They will be updated here shortly.

"Open-source" but no license? Maybe I'm just missing it (on mobile).

Nice renders though.

9dev• 4 years ago

Nope, there is none. Not even mentioned on the Readme. Somehow people tend to forget the licensing aspect of Open Source, it’s not just putting your code on display

Vespasian• 4 years ago

In this case you are technically not even allowed to check it out in most jurisdiction.

No license means no rights.

dark-star• 4 years ago

If, by "most jurisdictions", you mean the US and maybe Canada/Australia...

Because in "most jurisdictions" it's not actually illegal to look at things that have no license

Github ToS grants some permissions

dagw• 4 years ago

From the Github docs: "If you publish your source code in a public repository on GitHub, according to the Terms of Service, other users of GitHub.com have the right to view and fork your repository."

So by using GitHub, he has implicitly 'signed over' some rights to other GitHub users.

Someone opened an issue about this and the creator responded saying that they’ll add a license.

Will be nice a comparison with Povray.

wiz21c• 4 years ago

How does it compare to Blender (in terms of quality of render) ? I ask because ray tracers have progressed so much that I don't know how to compare them anymore...

capableweb• 4 years ago

In terms of quality, the difference between quality of ray tracing engines is mostly up to the user at this point. People who have zero experience with Manta Ray won't be able to do better renders than people with non-zero experience with Cycles, and vice-versa. Same goes if you use Renderman, V-ray, POV-Ray, Mental or any other renderer. In capable hands, they can all do absolutely wonderful renders, but again, mostly up to the user rather than the engine.

In terms of user experience, if you're using Blender, it's much easier to use Cycles as it's already integrated in Blender, while Manta Ray is a standalone renderer.

zokier2• 4 years ago

Blender is not itself a renderer. It comes with (at least) two built-in renderers, Eevee and Cycles, and can be interfaced to many others.
