I am using splines to position a camera and got an unexpected result. How can I
output the value of the spline (at a clock value) to #debug.
#declare Cam_Pos =
spline {
quadratic_spline
0.00, <0.894, -1.569, 2.334>
0.25, <2.939, -0.06, 2.035>
0.75, <2.939, -0.06, 2.035>
1.00, <3.061, -1.763, 2.335>
}
Regards
Stephen

#debug VStr(Cam_Pos(clock))

Forgot something: you have to #include "strings.inc" first. Or you could
use the built-in str() function and do what VStr() does, but it's more
work.

Thanks Christopher,
That looks just the thing.
