Detailed Description

States set on a QRenderStateSet are set globally, contrary to the per-material states that can be set on a QRenderPass. By default, an empty QRenderStateSet will result in all render states being disabled when executed. Adding a QRenderState state explicitly enables that render state at runtime.

The RenderStateSet is enabled when added to the active frame graph:

// using namespace Qt3DRender;

Qt3DCore::QEntity *rootEntity = new Qt3DCore::QEntity();

QRenderSettings *renderSettings = new QRenderSettings();

QViewport *viewport = new QViewport();
QCameraSelector *cameraSelector = new QCameraSelector(viewport);

QClearBuffers *clearBuffers = new QClearBuffers(cameraSelector);

QRenderStateSet *renderStateSet = new QRenderStateSet(cameraSelector);
QCullFace *cullFace = new QCullFace(renderStateSet);

Member Function Documentation

void QRenderStateSet::addRenderState(Qt3DRender::QRenderState *state)

Adds a new QRenderState state to the QRenderStateSet instance.

Note: Not setting any QRenderState state on a QRenderStateSet instance implies all the render states will be disabled at render time.

void QRenderStateSet::removeRenderState(Qt3DRender::QRenderState *state)

Removes the QRenderState state from the QRenderStateSet instance.

QList<Qt3DRender::QRenderState *> QRenderStateSet::renderStates() const

Returns the list of QRenderState objects that compose the QRenderStateSet instance.
