Has anyone here thought that  it could  be practical to have some kind of
vector format for a finish?

Example:
#declare Mirror = finish {ambient 0  diffuse 0 reflection 1}
could be
#declare Mirror= finish{ adr<0,0,1>}


Just a thought.

Have a great day

An interesting idea, however there would be so many floats within
such a "vector" it might be somewhat difficult to keep in mind what
goes where.  I believe there are currently 11 or more individual parts.
Also the way people write those out varies greatly, no set rule on
what goes first, second, third, etc.  Plus the fact that reflection itself can
be a vector already.
But not a bad idea if done certain ways.
Perhaps like:  finish { ad 0.1,0.6 sr 0.5,0.05 ps 0.3,80 re 0.9,1 mb 1,1 c 0.1 }
ad = ambient and diffuse
sr = specular and roughness
ps = phong and phong_size
re = reflection and reflection_exponent (also possible, re <0.9,0.9,0.9>,1)
mb = metallic and brilliance
c = crand

There's also 'irid' but it has it's own statement within the finish.
For shorthand it couldn't hurt to do in such ways I suppose.

This would be very bad for readability and maintainability, and all it 
would do is save a bit of typing. And your syntax limits you to float 
parameters...all three of those can take colors. And what about 
specular, angle dependant reflection, etc?

Intresting, I did not know that :)

This was only a general idea of how it could be done, I expected that there
would be problems  scince there are more keywords than those three.

Thanks for your input.
