3d transformation gizmo built on top of the egui library.

Try it out in a web demo

Usage

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.into();
}

For a more complete example, see the demo source code.

The gizmo accepts matrices as Into<[[f32; 4]; 4]>, which means it is easy to use with matrix types from various crates such as nalgebra, glam and cgmath.
