The question is, is this a viable niche? You’re using SceneKit, but you’ve hit performance cliffs. You want to use Unity/Unreal, but they’re massive and cumbersome. Is there a (cross-platform) middle road for small teams building interactive/entertainment/edu/AR/viz apps?
I haven’t done much research yet, but I see things like Cinder, OpenFrameworks, and any number of nascent projects and I have to think things could be simpler and easier. You shouldn’t have to go the full Godot to add 3D to your app.
It was one of the reasons behind the creation of Filament (although it’s not quite enough on its own). Apps could either use GL/Vulkan or a full-blown game engine. That’s also why we focus a lot on binary size
Love the Filament approach. It’s very close to what I’m envisioning. I’m learning a lot from you right now.
The grander vision would be to have utilities on top of it to do assets loadings, text, 2D vector rendering, maybe a scene graph for those who like this kind of things, etc. as individual/optional libraries. It can be done by clients today (ex: ImGui works with public APIs only)
Sceneform does a lot of these things atop Filament today, yes? Just not on, say, native iOS?
Yes, Sceneform plays that role on Android but requires Java/Kotlin. It’s also an all or nothing approach.
Someone will address this.
This is exactly why I created a codebase called Polymer. It's more targeted at desktop AR/VR development, but the renderer was designed for mobile. I'm also working on a MoltenVK backend. DM me if you want access on GitHub.
Would love to take a look. wm@warrenmoore.net / GH: warrenm
It's possibly a bit fragmented right now, but I think worth looking at: Filament, bgfx, sokol_app/sokol_gfx. What these all might be lacking is "good tooling" though.
Indeed, familiar with all. I think they’re one layer lower than what I’m envisioning, but very much on-point with respect to being shaped like modern GPU APIs.
So, sounds like what you want is a cross-platform and open source SceneKit :)
and with a C API please. my heart bleeds when I see all those nice higher-level APIs on OSX that will always remain obscure because they're written in obscure languages, and will never 'escape into the free world' ;)
I can assure you, macOS also has terribly obscure low level APIs. ;)
Is there an example of a library being sellable, so that it can make enough profit to become what you’re talking about? It seems to me that frameworks + GUI wrappers are more marketable so that’s what every long-lived popular solution is.
Not in recent history AFAIK, but I’ll throw two years of my life at the wall in an attempt to make it stick.
You can if you find the right need to address, like @sehurlburt and her team have accomplished.
If anyone wants to take a crack at the business side of it (specifically business, not the technical details) I always love strategizing about that and helping more small companies take off 
To be fair - cinder and oF also supply mesh loading, audio playback, video playback, device integration, networking, midi, osc, font rendering, windowing, event management and other shit that’s all cross platform. They do A LOT.
Most of my clients don’t care about most of those things. Specificity is an asset.
Totally, i was just 'defending the bloat' ;)
