Examples of the Scene Description Language
[edit]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
