No, but the macro do exist.

You didn't miss anything.

Depends on how many you want to make, or how many adjustments you want to do, or
if you're going to use it in an animation, where it needs to be parameterized.

A macro taking Start, End, and Radius as arguments would save a lot of work.

I have no idea. I am a "newuser". I started with the boxes first

https://ceving.github.io/breakout/

and did the player later on. But your suggestion sounds right. I will try it.

There is also another optimization I need to add. Right now I create the
different colors with a Makefile and sed:

https://github.com/ceving/breakout/blob/main/Makefile

But I think Povray's DSL should be sufficient to do the iteration. I still need
to find out how.

Makefile ans sed  are powerful tools on Linux...

... but POVRay makes it easy

How ? have a look at the animations and the demo scenes in portfolio
folder like allpatterns.pov, t_textures_.pov, ...
