NUMERICAL SPACE / CUBES

POV-Ray has many internal functins and
control comands. So we can easily make
arranged groups of objects.
For example, you can get 10x10x10=1000
cubes in the X-Y-Z space by the script
I show right. They will be colored one
by one with the position.
I can get tipical computer graphics by
this way on X-Z plane and trigonometrical
functions or other. Images in this page
are those I got from that. I colored
them by the value of Y direction to show
their structure clearly.

I wrote functions I used for all images
so that you can get similar images.

    #declare Cy=0
    #while (Cy < 11)
    #declare Cz=0
    #while (Cz < 11)
    #declare Cx=0
    #while (Cx < 11)
    box { <-0.15,-0.15,-0.15> <0.15,0.15,0.15>
    translate < Cx, Cy, Cz >
    pigment { color red 1-Cx/10 green Cy/10 blue 1-Cz/10}
    }
    #declare Cx=Cx+1
    #end
    #declare Cz=Cz+1
    #end
    #declare Cy=Cy+1
    #end

    #declare C = (Cx*Cx+Cz*Cz)*0.004
    #if ( C<3.1415*1.2 )
    box { <-0.15,-0.15,-0.15> <0.15,0.15,0.15>
    translate
    finish {phong 0.3} finish {ambient 0.5}
    pigment {color red 1-sin(C-3.1415/2) green 0.2-0.2*sin(C-3.1415/2) blue sin(C-3.1415/2)}
    }
