YESSSS!!!!
Can we rehash gamma and srgb conversion again? *PLEASE*?
That's totally one of my favorite topics!

Personally, I would rather dance on a bed of hot coals instead; it would
probably be less painful, and far less confusing...

Thanks! RE_Cylinder works fine.

There are some minor artifacts on both ends, but maybe they are normal, I don't
know.

I used the gamma value just as a brightness slider. The images were too dark
with 1.

Well yeah, you had a black background.
use
sky_sphere {pigment {rgb 1}}
and see the dramatic difference.

Do you really have to use a macro for such a simple object ?
Back to basics csg : a simple merge { sphere{} sphere{} cylinder{} } is
more than enough, but maybe I've missed something?

No, but the macro do exist.

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, ...
