Updated Motion Camouflage Script

This weekend I worked on developing the “dragonfly” POV-Ray script some more. There are more details behind this idea in an earlier post.

Here is the linear intercept video, without motion camouflage. You can see more movement against the background, especially in the early part. I think it helps to see this first for comparison to the motion camouflage animation.

Here is the updated motion camouflage video.

Here is the POV-Ray script

camera {      
  #declare viewx=2-clock*5 ;
  #declare viewz= -2-clock*2.5 ;
  location <viewx, 2, viewz>
// viewer trajectory
              
// motion camo look at fixed

    background { color Gray }       

  plane { <0, 1, 0>, -1
    pigment {
      checker color Copper, color Blue
    }

    plane { <0, 0, 1>, 20
    pigment {

      scale 3
    }
  }        
  

  sphere {
   <0,1,0>, 0.2 
   pigment{color Red}

  }  
  

    sphere {  // dragonfly   
    
    // motion camo sequence  
    #declare dfz= 20-clock*24;

    #declare zint=20;           
    // slope of line, rise over run
    #declare slopedf=(xint-viewx)/(zint-viewz); 
    // intercept of line, solve by algebra
    #declare intercept=viewx-viewz*slopedf;
    // x position from liner line equation 
    #declare dfx= dfz*slopedf+intercept;  
      
    <dfx,2,dfz>, 0.2

   // intercept course
