3D Path Rendering DetailsStencil step usesGLfloat slope = -0.05;GLint bias = -1;glPathStencilDepthOffsetNV(slope, bias);glDepthFunc(GL_LESS);glEnable(GL_DEPTH_TEST);Stenciling step usesglPathCoverDepthFuncNV(GL_ALWAYS);ObservationStencil step is testing—but not writing—depthStencil won’t be updated if stencil step fails depth test at a sampleCover step is writing—but not testing—depthCover step doesn’t need depth test because stencil test would only pass if prior stencilstep’s depth test passedTricky, but neat because minimal mode changes involved
