该类在 Qt 5.7 引入。
enum | CullingMode { NoCulling, Front, Back, FrontAndBack } |
QCullFace (Qt3DCore::QNode * parent = nullptr) | |
Qt3DRender::QCullFace::CullingMode | mode () const |
void | setMode (Qt3DRender::QCullFace::CullingMode mode ) |
void | modeChanged (Qt3DRender::QCullFace::CullingMode mode ) |
QCullFace sets whether the front or back facets are culled. Facets include triangles, quadrilaterals, polygons and rectangles.
It can be added by calling the addRenderState() method on a QRenderPass :
// using namespace Qt3DRender; QRenderPass *renderPass = new QRenderPass(); // Create a front face culling render state QCullFace *cullFront = new QCullFace(); cullFront->setMode(QCullFace::Front); // Add the render state to the render pass renderPass->addRenderState(cullFront);
Or by calling the addRenderState() method on a QRenderStateSet :
// using namespace Qt3DRender; QRenderStateSet *renderStateSet = new QRenderStateSet(); // Create a front face culling render state QCullFace *cullFront = new QCullFace(); cullFront->setMode(QCullFace::Front); // Add the render state to the render pass renderStateSet->addRenderState(cullFront);

This enumeration specifies values for the culling mode.
