Detailed Description

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 in the 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
         }
     ]
 }
