Integration with Rust 3D Graphics Libraries

[JohnPiwinski]

I am attempting to write a tool to assist doctors with visualizing tissue biopsies that have been stained with multiple fluorescent dyes to identify cell types. How difficult would it be to include a 3D graphics window in a Slint application for this purpose? I have some experience using this library, and I heard someone mention that I could employ glium, wgpu, or winit directly to write the 3D content to the graphics window. I am afraid that if I do not use an official API, the code will be fragile and make future updates prohibitively difficult.

Thank you very much

Hi! I Think this should be quite doable, three-d looks very promising and flexible. Depending on how you'd like to integrate the rendering into your UI, I think the https://github.com/slint-ui/slint/tree/master/examples/opengl_texture and the https://github.com/slint-ui/slint/tree/master/examples/opengl_underlay might serve as starting points. Slint provides a current OpenGL context in the rendering notifier callbacks, along with a get_proc_address function pointer to initialise your own GL wrapper.

With three-d, I don't think you can use the window module, but Context has the right signature that matches what we provide.

Thanks so much! I'll look into these examples and provide an update if I get a working demo.

Hi @JohnPiwinski,
How did it go?

I just figured this out and posted the answer to my own question in the disussions over at three-d. the link is asny/three-d#509
So far, nobody there has commented on it (though I just posted it) - but it works so it cannot be thaat wrong.
