Concept: 3D Objects and Coordinate Systems

Understanding how Blender represents 3D space is key to effective modeling and animation.

Objects and Meshes

In Blender, everything visible in a scene is an Object. Objects can contain different data types:

• Mesh (geometry made of vertices, edges, faces)
• Curve
• Text
• Light
• Camera

Coordinate System

Blender uses a right-handed coordinate system:

• X-axis (red): left/right
• Y-axis (green): front/back
• Z-axis (blue): up/down

The origin point (0,0,0) is the center of the world.

Local vs Global Space

• Global space: position relative to world origin.
• Local space: position relative to the object’s own origin.
