tracePieSector
tracePieSector(
ctx,cx,cy,r0,r1,a0,a1):void
Defined in: core/instanced-vector.ts:133
One pie wedge’s sector between radii r0 ≤ r1, angles in radians: r0 = 0 is the plain sector from the
centre, r0 > 0 the annular sector of its outer band (#507). The one geometry the Canvas/SVG Scene pie
(tracePieWedges, network/glyphs.ts) and the toSVG() export of the instanced pie trace,
so the vector band meets the WebGL shader’s r > 1 − border test on the same circle.
