Detailed Description

The output of this effect is a modulation of the input color and coverage for a circle. It operates in a space normalized by the circle radius (outer radius in the case of a stroke) with origin at the circle center. Three vertex attributes are used: vec2f : position in device space of the bounding geometry vertices vec4ub: color vec4f : (p.xy, outerRad, innerRad) p is the position in the normalized space. outerRad is the outerRadius in device space. innerRad is the innerRadius in normalized space (ignored if not stroking). Additional clip planes are supported for rendering circular arcs. The additional planes are either intersected or unioned together. Up to three planes are supported (an initial plane, a plane intersected with the initial plane, and a plane unioned with the first two). Only two are useful for any given arc, but having all three in one instance allows combining different types of arcs. Round caps for stroking are allowed as well. The caps are specified as two circle center points in the same space as p.xy.

◆ addToKey()

void CircleGeometryProcessor::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.
