Lines Matching full:circle
1125 concentric circles, with the color interpolated from the start circle
1126 (at t=0) to the end circle (at t=1).
1129 interpolated circle that intersects that point. The center
1130 of the desired circle (Cx, Cy) falls at some distance t
1137 The radius of the desired circle (r) is also a linear interpolation t
1168 If a<0, the start circle is entirely contained in the
1169 end circle, and one of the roots will be <0 or >1 (off the line
1170 segment). If a>0, the start circle falls at least partially
1171 outside the end circle (or vice versa), and the gradient
1172 defines a "tube" where a point may be on one circle (on the
1572 // returns angle in a circle [0..2PI) -> [0..255]
