virtual void setClearColor(const QColor &color)=0
Sets background color of the scene.
virtual Qt3DRender::QRenderSettings * renderSettings()=0
Returns access to the engine's render settings (the frame graph can be accessed from here)
virtual Qt3DRender::QCamera * camera()=0
Returns pointer to the engine's camera entity.
virtual QSurface * surface() const =0
Returns the surface of the engine.
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.
bool shadowRenderingEnabled()
Returns whether shadow rendering is enabled.
