## Properties

- horizontalLines : int
- horizontalStep : real
- verticalLines : int
- verticalStep : real

## Detailed Description

This helper implements grid geometry, which allows showing a grid in a scene.

For example, the following snippet would display a grid with 19 cells in both directions in a scene that has one light. Without further transformations, the grid is facing the camera by default.

     View3D {
         anchors.fill: parent
         camera: camera

         PerspectiveCamera {
             id: camera
             position: Qt.vector3d(0, 0, 600)
         }

         DirectionalLight {
             position: Qt.vector3d(-500, 500, -100)
             color: Qt.rgba(0.4, 0.2, 0.6, 1.0)
             ambientColor: Qt.rgba(0.1, 0.1, 0.1, 1.0)
         }

         Model {
             scale: Qt.vector3d(100, 100, 100)
             geometry: GridGeometry {
                 horizontalLines: 20
                 verticalLines: 20
             }
             materials: [ DefaultMaterial { } ]
         }
     }
