Lines Matching full:circle
1406 concentric circles, with the color interpolated from the start circle
1407 (at t=0) to the end circle (at t=1).
1410 interpolated circle that intersects that point. The center
1411 of the desired circle (Cx, Cy) falls at some distance t
1418 The radius of the desired circle (r) is also a linear interpolation t
1449 If a<0, the start circle is entirely contained in the
1450 end circle, and one of the roots will be <0 or >1 (off the line
1451 segment). If a>0, the start circle falls at least partially
1452 outside the end circle (or vice versa), and the gradient
1453 defines a "tube" where a point may be on one circle (on the
2045 // returns angle in a circle [0..2PI) -> [0..255]
