\qmltype GridGeometry \inqmlmodule QtQuick3D.Helpers \inherits Geometry
A custom geometry provider for rendering grids.
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.
\badcode 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 { } ] } }
