Einführung

The geometry of a scene is constructed from one or more objects. These objects can range from lights to illuminate your scene, basic 2D and 3D shapes to fill it with models, armatures to animate those models, to cameras to take pictures or make video of it all.

Each Blender object type (mesh, light, curve, camera, etc.) is composed from two parts: an Object and Object Data (sometimes abbreviated to „ObData“):

Object

Holds information about the position, rotation and size of a particular element.

Object Data

Holds everything else. For example:

Meshes:

Store geometry, material list, vertex groups, etc.

Cameras:

Store focal length, depth of field, sensor size, etc.

Each object has a link to its associated object-data, and a single object-data may be shared by many objects.
