Hi I'm new to pov newsgroup.
Lately I've been using splines for coloring and scaling instead of just tracing
paths for objects, I was wondering if anyone knew what the technical term for
this is other than just spline scaling/coloring.
Some example code is below.
camera {look_at 0 location -25*z-10*x}
background {rgb 1}
light_source{<-25,5,-25> rgb 1}
#declare msp=spline{linear_spline
0,<2,1,2>,
5,<3,1,5>
5.5,1,
6,<.1,1,10>
10,<1,1,1>}
#declare msp2 = spline{linear_spline
0,<5,0,0>,
4,<0,5,0>,
5,<0,10,3>,
6,<5,11,0>,
10,<0,-5,0>}
#declare msp3 = spline{linear_spline
0,y,
5,y,
9.1,x,
10,1}
#declare obj1 = union{
#declare a1 = 0;
#while (a1<=10)
sphere{0,.5 pigment {rgb msp3(a1)}
scale msp(a1) translate msp2(a1) }
sphere{0,.5 pigment {rgb z} scale msp(a1) translate msp2(a1)-8*x}
#declare a1 = a1+.01;
#end}
object{obj1}
