  Reflection problem. (Message 1 to 5 of 5)  
From: Nekar Xenos
Subject: Reflection problem.
Date: 10 Dec 2001 02:30:38
Message: <3c14649e@news.povray.org>
Is this a bug or am I missing something? The bottom of the "J" reflects the sky
sphere but everything is enclosed in a box. If I get rid of the sky-sphere it
reflects black. This should just reflect the box texture.

The source is posted to povray.binaries.scene-files.

Any help will be appreciated.

Thanks.

It is the box, indirectly.  It's where the box ends in the reflection
apparently, as you can see better by using:

box { <-1000,-1000,-1000>, <1000,1000,0>
 clipped_by {plane {-z,100}}

You'll have to scale it or move it differently, possibly like:

box { <-1000,-1000,-1000>, <1000,100,0>

I'm not sure what you mean here.

Sorry that didn't help.

Any other ideas anyone?

I was clipping off the box after moving it to the -z side so that lights and
camera were still able to see the scene ok.

Note that I commented out the clipped_by when using that, as well as upped
the max_trace_level to 10, whether or not that made any difference.
Image attached shows how "J" looks as I had seen it, not sure what is
acceptable to you but it looked passable to me.

My apologies for taking you on a wild goose chase, Bob. I wanted the scene
inside the box. I just fixed the z co-ordinates of the box to -1000 and
everything was fine.

I think I need more sleep...
