Can anyone help me figure out what's wrong with this sweep? It seems to
work fine with a linear_sphere_sweep, but catmull_rom and b_spline
sweeps give me an error "Attempt to maloc zero size block..." Maloc?
Any hints?
sphere_sweep {
b_spline_sphere_sweep
3,
<0, .5, 0>, .5
<.75, 0, 0>, .25
<0, -1, 0>, .01
texture { pigment { color Black } }
finish { phong .4 }
}
The idea is to have two of these for a yin-yang symbol...
See ya...

Catmull-Rom and B-Spline are cubic forms of interpolation. You need at
least 4 spheres to use either one (and 2 spheres to use linear). Good
luck.
