Qt3DRender.QCullFace ¶

概要 ¶

详细描述 ¶

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);
