Detailed Description

The output of this effect is a modulation of the input color and coverage for an axis-aligned ellipse, specified as a 2D offset from center, and the reciprocals of the outer and inner radii, in both x and y directions.

We are using an implicit function of x^2/a^2 + y^2/b^2 - 1 = 0.

◆ addToKey()

void EllipseGeometryProcessor::addToKey	(	const GrShaderCaps &	,
		skgpu::KeyBuilder *
	)		const

inlineoverridevirtual

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

Implements GrGeometryProcessor.

◆ makeProgramImpl()

std::unique_ptr< ProgramImpl > EllipseGeometryProcessor::makeProgramImpl ( const GrShaderCaps & ) const

inlineoverridevirtual

Returns a new instance of the appropriate implementation class for the given GrGeometryProcessor.

Implements GrGeometryProcessor.

                                                                                   {
        return std::make_unique<Impl>();
    }

◆ name()

const char * EllipseGeometryProcessor::name ( ) const

inlineoverridevirtual

Human-meaningful string to identify this processor; may be embedded in generated shader code and must be a legal SkSL identifier prefix.

Implements GrProcessor.
