Detailed Description

Custom Qt Quick 3D geometry for rendering terrain meshes with height data.

This class generates a triangulated mesh grid with vertex positions, normals, and texture coordinates based on provided elevation data. The geometry is suitable for use with Qt Quick 3D Model items and supports dynamic updates when height data changes.

Note:

QML Type: Quick3DTerrainGeometry
