Display an arbitrary 3D mesh

[tbarusseau]

Hello! I'm using egui to make a 3D-model viewer, and am wondering how to display a 3D mesh.

I can see in the documentation that I can do ui.painter().add(egui::Shape::Mesh(/* Some mesh */)).

Mesh needs an indices array for triangles (which doesn't pose much issues), but also a Vertex array. However it's indicated that this is "the 2D vertex type", implying that there might be a 3D vertex type?

If there isn't, do I need to project each of my 3D-model's vertex to egui's 2D frame? Manually doing occlusion culling etc?

Thanks in advance.

3D is outside the scope of egui. You can project to 2D and do your own culling, but that is tedious.

I suggest you use something like macroquad (with egui-macroquad) and render your mesh to a texture and display it with egui::Image.

Thank you! Also thanks for having the discussions enabled.

Cheers and good luck for the future of this awesome project!
