Detailed Description¶
A
QAlphaCoverage
class enables alpha-to-coverage multisampling mode. When enabled, the fragment alpha value is used as a coverage for the sample and combined with fragment coverage value.QAlphaCoverage
does nothing if multisampling is disabled. Alpha-to-coverage is most useful when order independent blending is required, for example when rendering leaves, grass and other rich vegetation.It can be added to a
QRenderPass
by callingaddRenderState()
:QRenderPass *renderPass = new QRenderPass(); // Create a alpha coverage render state QAlphaCoverage *alphaCoverage = new QAlphaCoverage(); QMultiSampleAntiAliasing *multiSampleAntialiasing = new QMultiSampleAntiAliasing(); // Add the render states to the render pass renderPass->addRenderState(alphaCoverage); renderPass->addRenderState(multiSampleAntialiasing);Or to a
QRenderStateSet
by callingaddRenderState()
:QRenderStateSet *renderStateSet = new QRenderStateSet(); // Create a alpha coverage render state QAlphaCoverage *alphaCoverage = new QAlphaCoverage(); QMultiSampleAntiAliasing *multiSampleAntialiasing = new QMultiSampleAntiAliasing(); // Add the render states to the render state set renderStateSet->addRenderState(alphaCoverage); renderStateSet->addRenderState(multiSampleAntialiasing);See also
