checkout main` without worrying which repo I'm browsing.

#### `Shape::Callback`
Example:
* <https://github.com/emilk/egui/blob/master/examples/custom_3d_glow/src/main.rs>
* <https://github.com/emilk/egui/blob/main/examples/custom_3d_glow/src/main.rs>
`Shape::Callback` will call your code when egui gets painted, to show anything using whatever the background rendering context is. When using [`eframe`](https://github.com/emilk/egui/tree/master/crates/eframe) this will be [`glow`](https://github.com/grovesNL/glow). Other integrations will give you other rendering contexts, if they support `Shape::Callback` at all.

#### Render-to-texture
You can also render your 3D scene to a texture and display it using [`ui.image(…)`](https://docs.rs/egui/latest/egui/struct.Ui.html#method.image). You first need to convert the native texture to an [`egui::TextureId`](https://docs.rs/egui/latest/egui/enum.TextureId.html), and how to do this depends on the integration you use.
Examples:
* Using [`egui-miniquad`]( https://github.com/not-fl3/egui-miniquad): https://github.com/not-fl3/egui-miniquad/blob/master/examples/render_to_egui_image.rs
