Camera

The scene owns the camera: a position, a target, and a projection. In Python you set it through scene methods, not by mutating a raw camera struct.

scene.set_camera(position=(0.0, 0.0, 10.0), target=(0.0, 0.0, 0.0))
scene.set_view_width(16.0)

Orthographic (default)

Objects do not shrink with distance. set_view_width is how much world is visible horizontally. Height follows the scene frame.

scene.set_view_width(8.0)   # zoom in
scene.set_view_width(24.0)  # zoom out

Moving the camera in orthographic mode does not change the 2D crop. Use set_view_width.

Default view width is 16.0, which matches landscape bounds [-8, 8] × [-4.5, 4.5].

Perspective

For 3D scenes where depth should read as depth:

scene.set_perspective_camera(fov_y_degrees=45.0, near=0.1, far=100.0)
scene.set_camera(position=(4.0, 3.0, 8.0), target=(0.0, 0.0, 0.0))

up defaults to (0.0, 1.0, 0.0).

Animating the camera

timeline.animate_camera_frame(
    start_time=0.0,
    duration=2.0,
    position=(2.0, 1.0, 10.0),
    target=(0.0, 0.0, 0.0),
    ease="in_out_quad",
)
timeline.zoom_camera(start_time=1.0, duration=2.0, zoom=8.0, ease="in_out_quad")

zoom here is the target orthographic view width.

Preview orbit

In scene.preview(), you can orbit and pan in the window. That is inspection, not authored camera motion. Authored motion goes on the timeline so export matches preview timing.
