Can I declare the y component only?
For example, if I want to say,
#declare velocity[n].y=velocity[n].y*0.9;
Do I have to say,
#declare velocity[n]=<velocity[n].x,velocity[n].y*0.9,velocity[n].z>;
The former OUGHT to be good enough! I think pov gave me error messages
until I went to the trouble of the latter.....
