Detailed Description
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);
