I'm using sphere_sweep with cubic_spline to try to get a nice smooth curve, but
part of it is missing:
----
#version 3.5;
global_settings { ambient_light 0 assumed_gamma 1 }
background { rgb 0.05 }
light_source { <0,+1000,0> rgb 1 }
sphere_sweep
{
cubic_spline
6,
< 0 , 48 , 277 >, 1
< 0 , 88 , 166 >, 1
< 0 , 115 , 55 >, 1
< 0 , 115 , -55 >, 1
< 0 , 88 , -166 >, 1
< 0 , 48 , -277 >, 1
tolerance 0.1
pigment { color < 1 , 1 , 1 > }
finish { emission 1 }
}
camera
{
perspective
location < 320 , 100 , 0 >
angle 80
look_at < 0 , 0 , 0 >
}
----
The behaviour with linear_spline is also odd, there's a spike in the middle. I
can't see what I might be doing wrong. I'm using version
3.7.0.msvc10-sse2.win32 on Windows XP. Any suggestions?
