Detailed Description

Provides in-memory texture data from rendered map layers for 3D terrain visualization.

This class inherits from QQuick3DTextureData to provide texture data directly in memory, avoiding the need for temporary files. The map is rendered using QGIS rendering engine and the result is exposed as texture data for Qt Quick 3D.

Note:

QML Type: Quick3DMapTextureData
