Crate egui_gizmo

Provides a 3d transformation gizmo that can be used to manipulate 4x4 transformation matrices. Such gizmos are commonly used in applications such as game engines and 3d modeling software.

Creating a gizmo

For a more complete example, see the online demo at https://urholaukkarinen.github.io/egui-gizmo/. The demo sources can be found at https://github.com/urholaukkarinen/egui-gizmo/blob/main/demo/src/main.rs.

A basic example

let gizmo = Gizmo::new("My gizmo")
    .view_matrix(view_matrix)
    .projection_matrix(projection_matrix)
    .model_matrix(model_matrix)
    .mode(GizmoMode::Rotate);

if let Some(response) = gizmo.interact(ui) {
    model_matrix = response.transform();
}

The gizmo can be placed inside a container such as a egui::Window or an egui::Area. By default, the gizmo will use the ui clip rect as a viewport. The gizmo will apply transformations to the given model matrix.
