Detailed Description

The output of this effect is a hairline edge for quadratics. Quadratic specified by 0=u^2-v canonical coords. u and v are the first two components of the vertex attribute. At the three control points that define the Quadratic, u, v have the values {0,0}, {1/2, 0}, and {1, 1} respectively. Coverage for AA is min(0, 1-distance). 3rd & 4th cimponent unused. Requires shader derivative instruction support.

◆ addToKey()

void GrQuadEffect::addToKey ( const GrShaderCaps ,
skgpu::KeyBuilder  
) const
overridevirtual

Adds a key on the skgpu::KeyBuilder that reflects any variety in the code that the geometry processor subclass can emit.

Implements GrGeometryProcessor.
