Detailed Description

The QCullFace class specifies whether front or back face culling is enabled.

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);
