Examples of the Scene Description Language

The following is an example of the scene description language used by POV-Ray to describe a scene to render. It demonstrates use of the camera, lights, a simple box shape and the transforming effects of scaling, rotation and translation.

#version 3.6;

#include "colors.inc"

global_settings {

assumed_gamma 1.0

}

background {

color rgb <0.25,0.25,0.25>

}

camera {

location <0.0, 0.5, -4.0>

direction 1.5*z

right x*image_width/image_height

look_at <0.0, 0.0, 0.0>

}

light_source {

<0, 0, 0>

color rgb <1, 1, 1>

translate <-5, 5, -5>

}

light_source {

<0, 0, 0>

color rgb <0.25, 0.25, 0.25>

translate <6, -6, -6>

}

box {

<-0.5, -0.5, -0.5>

<0.5, 0.5, 0.5>

texture {

pigment {

color Red

}

finish{

specular 0.6

}

normal {

agate 0.25

scale 1/2

}

}

rotate <45,46,47>

}

The following script fragment shows the use of variable declaration, assignment, comparison and the while loop construct:

#declare the_angle = 0;

#while (the_angle <= 360)

box {

<-0.5, -0.5, -0.5>

<0.5, 0.5, 0.5>

texture {

pigment {

color Red

}

finish{

specular 0.6

}

normal {

agate 0.25

scale 1/2

}

}

rotate the_angle

}

#declare the_angle = the_angle + 45;

#end
