Constructor & Destructor Documentation

◆ HeightFieldGeometry()

HeightFieldGeometry::HeightFieldGeometry ( )

\qmltype HeightFieldGeometry \inqmlmodule QtQuick3D.Helpers \inherits Geometry

Since
6.4

A height field geometry.

This helper implements a height-field geometry. It defines a surface built from a grayscale image. The y-coordinate of the surface at a given point in the horizontal plane is determined by the pixel value at the corresponding point in the image. The image's x-axis and y-axis will go along the geometry's x-axis and z-axis respectively.

\qmlproperty vector3d HeightFieldGeometry::extents This property defines the extents of the height-field, that is the dimensions of a box large enough to always contain the geometry. The default value is (100, 100, 100) when the image is square.

\qmlproperty QUrl HeightFieldGeometry::heightMap \obsolete

This property defines the URL of the height map image.

Use \l HeightFieldGeometry::source instead.

\qmlproperty QUrl HeightFieldGeometry::source This property defines the URL of the height map image.

\qmlproperty bool HeightFieldGeometry::smoothShading This property defines whether the height map is shown with smooth shading or with hard angles between the squares of the map.

The default value is true, meaning smooth shading is turned on.
