详细描述

Enable alpha-to-coverage multisampling mode

A Qt3DRender::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. Qt3DRender::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.
