Now the cabin is well-framed (0.19-0.76), but the pond is off to the right (x=1.18) — because the pond is east of the cabin, and from this angle it's pushed right. The dock at (0.82-1.09) is also right-of-center. The cabin is left-center, pond right. That's actually a reasonable composition: cabin left, pond right. But the pond far edge is at y=-0.86 (below frame) and near edge at y=0.24. Only the top part of the pond is visible.

The fundamental issue: the pond is huge (radius 7) and located at (8,-7), while the cabin is at (-4,1). They're ~13 units apart. To get both in one frame from a reasonable distance, I need to be quite far back. Let me try a much more pulled-back camera with a moderate lens.

import bpy, math
from mathutils import Vector
from bpy_extras.object_utils import world_to_camera_view

cam = bpy.data.objects['Camera']
scene = bpy.context.scene

def set_cam(loc, target, lens=40):
    cam.location = Vector(loc)
    direction = Vector(target) - cam.location
    cam.rotation_euler = direction.to_track_quat('-Z', 'Y').to_euler()
    cam.data.lens = lens

def project(xyz):
    v = world_to_camera_view(scene, cam, Vector(xyz))
    return (round(v.x,3), round(v.y,3))
