Houses Generated by Scripts

Working on some scripts for creating houses.  This one uses Illustrator.  Pretty rough at this point.

POVRay code (use at your own risk):



global_settings {max_trace_level 5}
background {rgb <1,1,1>}
//camera {orthographic location <30-15*clock,0,0> rotate <clock*60,clock*30,clock*360> look_at <0,0,0> angle 22}
camera {orthographic location <0,20,-40> look_at <0,0,0> angle 20}
light_source {<80,100,40> rgb .5 }
light_source {<20,200,20> rgb .8 }
    
height_field {
    png "house_roofs.png"
    //smooth 
    translate <-.5,0,-.5>
pigment {
      gradient y       //this is the PATTERN_TYPE
      color_map {
        [0.0  color <.2,.1,.0>]
        [0.5  color <.2,.1,.0>]
        [0.7  color <.9,.4,.2>]
        [0.9  color <.9,.3,.2>]
        [1.0  color <.9,.3,.1>]
      }                     }
    scale <17, 1, 17>
    finish {roughness .1 specular .5 ambient .2}
  }



A collection of houses generated from the following gray scale.

This is the JavaScript that drives the Illustrator program.  Use at your own risk.
