I want to make a matlab program that creates a povray file for a face mesh
and then renders it. To do this , I need to able to run povray from the
command line (not the GUI command line but DOS command line). The
documentation example says: POVRAY +Isimple.pov +V +W80 +H60, but when I
try this on dos, I get:
'povray' is not recognized as an internal or external command,
operable program or batch file.
I searched for povray.exe, but it doesn't exist anywhere. I will appreciate
if someone could tell me the way to do this.
thanks,
Ankur

and put it in your path. Or type something like:
C:\Graphics\POV-Ray for Windows v3.5\bin\ POVRAY +I
C:\Graphics\POV-Ray for Windows v3.5\MYDIRECTORY\simple.pov +V +W80
+H60

If you have found your pvengine.exe you can wrap the
pov call in a script file, like the one below.
(I think I am not allowed to use an attachment here,
so I split a couple of the lines to fit in a
reasonable width).
You can call this function as:
povray(filename)
or with name-value pairs
povray(filename,'Width',320,'Height',240,'Options','+V')
you can use any number of name-value pairs. I have defined
only three, but you can easily add your own.
Note: this assumes that you have set your inifile in povray
and that you have selected
'Render/On Completion .../Exit POV-Ray for Windows'
from the menu.
There must be a way to specify the inifile you want to use
and that you want to exit after completion from the command
line, but I can not find how.
Actually, your mail prompted me to investigate some more.
After writing the above I found that I can specify the
inifile. There are still a number of problems however,
so I can not give a working version of the matlabscript
that includes the inifile yet.
- You have to specify the complete path for the inifile
- The commandline parser does not parse quotes. You can
therefore not use a long filename that includes spaces
and put "" around them. In fact you have to use the
DOSfilename. In my case "c:\progra~1\pov-ra~1.5\" etc
- it still complains that "never found section '' in file..."
This is where I give up :(

I'm doing a similar thing with the R statistics programming
environment. The R code writes an include file with the
statistics that I want rendered, then at the end it calls
(executes) pov SDL that generates a pretty graph.
Here is what I use in R:
(beware if this wraps)
system('C:\\progra~1\\pov-ra~1.5\\bin\\pvengine.exe C:\\Rpovray.ini
C:\\Rpovray.pov')
The location is standard for a Windows installation.
The double "\\" is because R uses "\" as a control character.
