How to move a camera in Blender 2.61 with Python

Question

I\'m searching for a simple script to move a camera in Blender 2.61 with Python. I thought this would be an easy task, but the Camera object has no properties like loc or someth

Answer 1

Perhaps the camera rigs at the bottom of this page could be a nice starting point.

Answer 2

furtelwart's answer was quite usefull. I did some more digging so you can also set some other very usefull properties regarding the camera and render.

import bpy

tx = 0.0
ty = 0.0
tz = 80.0

rx = 0.0
ry = 0.0
rz = 0.0

fov = 50.0

pi = 3.14159265

scene = bpy.data.scenes["Scene"]

# Set render resolution
scene.render.resolution_x = 480
scene.render.resolution_y = 359

# Set camera fov in degrees
scene.camera.data.angle = fov*(pi/180.0)

# Set camera rotation in euler angles
scene.camera.rotation_mode = 'XYZ'
scene.camera.rotation_euler[0] = rx*(pi/180.0)
scene.camera.rotation_euler[1] = ry*(pi/180.0)
scene.camera.rotation_euler[2] = rz*(pi/180.0)

# Set camera translation
scene.camera.location.x = tx
scene.camera.location.y = ty
scene.camera.location.z = tz

I'm using this script to make batch rendering. You can check it out here: http://code.google.com/p/encuadro/source/browse/renders/marker/model/marker_a4.py

It will be improved later to take command line arguments. I'm new to python and blender so this may be kind of amateur but it works.

Answer 3

A friendly user on reddit pointed me to one correct solution: The trick is to retrieve the camera as an Object, not as a Camera. With this way, you can set the location via the standard way and set keyframes.

If you want to set Camera specific objects, you have to retrieve it via bpy.data.cameras.

import bpy

if(len(bpy.data.cameras) == 1):
    obj = bpy.data.objects['Camera'] # bpy.types.Camera
    obj.location.x = 0.0
    obj.location.y = -10.0
    obj.location.z = 10.0
    obj.keyframe_insert(data_path="location", frame=10.0)
    obj.location.x = 10.0
    obj.location.y = 0.0
    obj.location.z = 5.0
    obj.keyframe_insert(data_path="location", frame=20.0)
