Convenience wrapper to simplify the creation of a 3D window ready to be used with QGIS.
Base class for 3D engine implementation.
virtual QSurface * surface() const =0
Returns the surface of the engine.
virtual Qt3DRender::QCamera * camera()=0
Returns pointer to the engine's camera entity.
virtual void setClearColor(const QColor &color)=0
Sets background color of the scene.
virtual void setSize(QSize s)=0
Sets the size of the rendering area (in pixels)
virtual void setFrustumCullingEnabled(bool enabled)=0
Sets whether frustum culling is enabled (this should make rendering faster by not rendering entities ...
virtual void setRootEntity(Qt3DCore::QEntity *root)=0
Sets root entity of the 3D scene.
virtual QSize size() const =0
Returns size of the engine's rendering area in pixels.
virtual Qt3DRender::QRenderSettings * renderSettings()=0
Returns access to the engine's render settings (the frame graph can be accessed from here)
On-screen 3D engine: it creates an OpenGL window (QWindow) and displays rendered 3D scenes there.
