  QR command line option (Message 1 to 6 of 6)

Hello people.

I was trying to get kpovmodeler to use 3.7beta, and thought I was there.
But then I got a command-line problem. It seems 3.7 doesn't accept +QR as
an option anymore (does it?).

Kpovmodeler always seems to generate +(or -)QR, so this means some patch
to the source code...

I couldn't find any reference to the QR flag in the changelog. Is this
change documented somewhere?

Taking a good look at the documentation, both 3.6 and 3.7, the only +Q 
something I can find is +Qn, or +qn, used to set the quality of the 
rendering.
You need an integer in the range 0..11 after the "Q".

In 3.6, the "R" seems to be ignored, or it assume that anything not 
numeric means to use the default of 9, and it generate an error when you 
use 3.7.
On the POV side, it's just that 3.7 is more strict in what you can use.
Maybe it was a valid switch in some version older than 3.6.

It looks like a bug in Kpovmodeler as +QR/-QR is NOT a valid command 
line argument in 3.6.

  I believe kpovmodeler was designer for POV-Ray versions older than 3.6.
Probably older than 3.5.

That switch has been deprecated for years, at least since 3.6, which 
doesn't even mention it in its documentation, and just gracefully ignore 
it with the following warning:

     Radiosity commandline/INI switch is not needed in POV-Ray 3.5.
     Add a radiosity{}-block to your scene to turn on radiosity.

Unfortunately, it will only output this message if the parameter is 
turned /off/, so some pepople may not have been warned about it.

Looking at that message, I'd say it was already deprecated in version 3.5.

It's very probable that the last version that effectively used it was 3.1.

Ok guys

Apologies for not replying earlier. Internet has been dodgy for quite a
while (just got awakened by an alarm on the telcom line, I guess
they're finally repairing it).

Fine about the QR option - I'll try to update the KPM source code for
that problem. Thanks for the info.

John
