RadialGradientFilling

RadialGradientFilling[{col1,col2,…,coln}] is a two-dimensional graphics directive specifying that faces of polygons and other filled graphics objects are to be drawn using concentric circles of colors coli.

RadialGradientFilling[{r1,r2,…,rn}->{col1,col2,…,coln}] uses the colors coli at radii ri.

RadialGradientFilling[{r1,r2,…,rn}->{col1,col2,…,coln},{x,y}] radiates from the center point {x,y}.

RadialGradientFilling[{r1,r2,…,rn}->{col1,col2,…,coln},{{x,y},{r1,r2}}] radiates from the center point {x,y} in concentric axis-aligned ellipsoids with semiaxes length proportional to ri.

RadialGradientFilling[{r1,r2,…,rn}->{col1,col2,…,coln},{{x,y},{r1,r2}},padding] uses the specified padding when drawing beyond the boundary radii r1 and rn.
