Development

Part of the Lexx just noodling animation The Lexx itself is so complicated even a modestly good copy of it is difficult. There is always something to learn along the way. The moving parts are two hemisphere (spere clipped_by plane) that rotate open. The problem is to have the opening part facing outward regardless of its location. #declare tt = 0; #while (tt < 360) object {eyec rotate 90*x rotate<0,0,tt> rotate<-80*sin(pp*tt),70*cos(pp*tt),0> translate } #declare tt = tt + 9 ; #end #declare tt = 0; #while (tt < 360) object {eyec rotate 90*x rotate<0,0,tt> rotate<-80*sin(pp*tt),80*cos(pp*tt),0> translate } #declare tt = tt + 9 ; #end The second rotate in each block changes, one for each ring around the "north pole." Look carefully and you see that spherical geometry you ignored or avoided in high school.
