void requestCaptureImage() override
Starts a request for an image rendered by the engine.
void setRootEntity(Qt3DCore::QEntity *root) override
Sets root entity of the 3D scene.
void setClearColor(const QColor &color) override
Sets background color of the scene.
QWindow * window()
Returns the internal 3D window where all the rendered output is displayed.
Qt3DRender::QRenderSettings * renderSettings() override
Returns access to the engine&#39;s render settings (the frame graph can be accessed from here) ...
Qt3DRender::QCamera * camera() override
Returns pointer to the engine&#39;s camera entity.
void imageCaptured(const QImage &image)
Emitted after a call to requestCaptureImage() to return the captured image.
QSize size() const override
Returns size of the engine&#39;s rendering area in pixels.
void setFrustumCullingEnabled(bool enabled) override
Sets whether frustum culling is enabled (this should make rendering faster by not rendering entities ...
