What effect does scaling a camera have on focal_blur?
I have two cameras, and they should both produce the same result. But
they don't.
// focal blur camera
camera {
location <0,0,-5>
look_at <0,0,0>
right x*image_width/image_height
up y
aperture 1.0 // [0...N] larger is narrower depth of field
(blurrier)
blur_samples 10 // number of rays per pixel for sampling
focal_point <0,0,0> // point that is in focus <X,Y,Z>
confidence 0.95 // [0...<1] when to move on while sampling
(smaller is less accurate)
variance 1/200 // [0...1] how precise to calculate (smaller
is more accurate)
scale 2
}
/*
