By the looks of the code, I assume this is about the Blender to POV exporter, so
unfortunately I can't comment much on the plugin code itself. But from my point
of view as a person who's got used to tuning all scene settings by hand solely
in POV, I can see quite wild numbers inside the camera syntax. It's quite
difficult to figure out what actually points and where. But I guess this is at
least partly because of the way the plugin works.
However, what concerns me most is the actual focal_point
<1.13652,4.92175e-08,1.12596> that seems to be way off. I don't know what kind
of focal blur possibilities there are in Blender, but in POV you can imagine the
focal_point as an invisible "plane" rotated as <90, 0, 0> in relation to the
camera direction. Everything along that plane in x and y axis are on focus, and
everything outside, meaning closer to or further from the camera are blurred
according to the value of aperture.
If the idea for focal blur in this case was to have eg. a smaller spot in focus
that blurs the rest of the scene in a circle or something similar, then I'm
afraid that's not how focal blur works in POV.
I tried to mimic your camera angle more or less with my own camera syntax below.
I don't know which one of the cubes was meant to be on focus, but to be clear
with my example I kept it on the one in the center.
camera {
location <0, 0, -9>
look_at <0, 0, 0>
right x*image_width/image_height
focal_point <0, 0, -1>
aperture 0.35
blur_samples 25, 100
variance 1/10000
rotate <30, -135, 0>
}
And here's the result (though it seems to be horizontally flipped compared to
yours):
