详细描述

Custom geometry allows using application-generated vertex and index data, that can possibly change dynamically as well. To use custom geometry, do not assign a .mesh file as the source to a Model. Instead, set its geometry property to reference a Geometry object.

A typical way of implementing custom geometry is by creating a QQuick3DGeometry subclass in C++ and registering the new type for use with QML.

It is also possible to use the built-in custom geometry provider GridGeometry Helpers module. The following is an example of GridGeometry . Any application-provided Geometry subclass can be taken into use in the same manner.

import QtQuick3D.Helpers
Model {
    geometry: GridGeometry {
    }
    materials: [
        DefaultMaterial {
            diffuseColor: "white"
            lighting: DefaultMaterial.NoLighting
        }
    ]
}
