Configurar PovRay en Ubuntu

Una configuracion

Vamos a probar una configuracion por defecto, a partir de la instalacion mediante APT,

 sudo apt-get install povray* 

, instala los paquetes "povray-include, povray-examples, povray" version 3.7

 

Configurar el perfil y añadir variables de entorno

En el directorio $HOME se creara ".povray/{version}/" alli incluiremos el fichero povray.conf,que se encuentra en "/etc/povray/" , vemos que necesita la variable INSTALLDIR por defecto apunta a "/usr/share/povray-{version}/" tambien indicamos los directorios de Lectura/Escritura.

"/usr/share/povray/3.7/scripts", se encuentran scripts que permiten renderizar los ficheros .pov de una forma mas sencilla.

  
povray -h
