rend3 VS blackjack

The WGPU people are still working through lock conflicts in that area. The idea with Vulkan land is that you should be able to load content while rendering is in progress. For that to be useful, all the layers above Vulkan also have to have their locking problems hammered out. Most open source game engines don't do that yet. Unreal Engine and Unity do, which is why you pay for them for your AAA title.

The big problem I have with bevy here is that they seem to be very much against bevy being reusable across the ecosystem. Every feature has to be bevyfied into an ECS thing. There's no way one can use bevy_input for input handling outside of bevy, or bevy_audio for audio, or bevy_render to get a 3d renderer like https://rend3.rs/. The Rust ecosystem would've been so much better off if bevy wasn't creating a walled garden and draining insane amounts of effort just for itself, but say instead used rend3 for its rendering, so that other efforts in rust gamedev didn't have to reimplement everything from scratch.

We have our own engine. There aren't really full engines available in the Rust ecosystem. Bevy attempts to fill this, but it's far from being feature complete. There's also https://fyrox.rs/, but that's also work in progress. There's also https://rend3.rs/ which is just a 3d renderer, so you'll need to build the rest of the engine yourself.

That's been fixed. It was one of those things where a complicated workaround for Rust's ownership rules, one that required maintaining internal consistency between multiple tables, was inconsistent.

Rend3 crashes The library's internal memory allocator for GPU objects is losing objects and panicking. This seems to be a race condition that comes up once you get past displaying static scenes and start having moving objects. Rend3 has one overworked main developer. If you're qualified to work on GPU-level stuff, which I am not, that project could use help.

I personally use Rend3, ability to use WGPU to make my own render effects, but I still get to build my own engine around it, although I'm waiting for the vertex-pulling branch to be merged before I really get going

My specific use case? That would be this: https://github.com/setzer22/blackjack

Very nice! I too have worked on implementing mesh data structures in Rust as part of my project https://github.com/setzer22/blackjack

Reasons why this would be great: - Interoperability between different libraries (importers, exporters, procedural mesh transformations, renderers, slicers, geometry analysis, etc.) - As a "backend" for projects like blackjack

Blackjack https://github.com/setzer22/blackjack a procedural modelling application; node-driven interface where you can compose operations to create a 3d mesh in a non-destructive way.

Very impressive. Looks similar in some respects to: https://github.com/setzer22/blackjack

was going to ask why lua? but then i saw you already had https://github.com/setzer22/blackjack/blob/main/doc/why_lua.md

Speaking of Houdini, https://github.com/setzer22/blackjack is an excellent open source alternative that loses a ton of cruft and is scriptable in Lua. I highly recommend checking it out if this is your kind of thing
