详细描述

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.

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);
clearBuffers->setBuffers(QClearBuffers::ColorDepthBuffer);
QRenderStateSet *renderStateSet = new QRenderStateSet(cameraSelector);
QCullFace *cullFace = new QCullFace(renderStateSet);
cullFace->setMode(QCullFace::Front);
renderStateSet->addRenderState(cullFace);
renderSettings->setActiveFrameGraph(viewport);
rootEntity->addComponent(renderSettings);

成员函数文档编制

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

Adds a new QRenderState state 到 QRenderStateSet 实例。

注意： 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 )

移除 QRenderState state 从 QRenderStateSet 实例。

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

Returns the list of QRenderState objects that compose the QRenderStateSet 实例。
