orthographic camera
// orthographic projection using parallel camera rays
// Could be used to render a planar image map, for example
camera {
orthographic
location <0,0,-1> // position & direction of view
look_at <0,0,0>
right 1*x // horizontal size of view
up 1*y // vertical size of view
}
/*
box { // this box fits exactly in view
<-0.5, -0.5, 0>, <0.5, 0.5, 0>
texture { pigment { rgb <1, 0, 1> } }
}*/
