The creation of a 3D scene needs at least three key components: Models, Materials and Lights. In this part, the first of these is covered, that being modeling. Modeling is simply the art and science of creating a surface that either mimics the shape of a real-world object or expresses your imagination of abstract objects.

Modeling can take many forms in Blender depending on the type of object you are trying to model. Some objects are not able to be modeled, these being:

  • Speakers
  • Cameras
  • Lamps


Depending on the type of object you are trying to model, there are different types of modeling mode. Because modes are not specific to modeling they are covered in different parts of the manual.

Edit Mode

Edit mode is the main mode that modeling takes place. Edit mode is used to edit the following types of objects:

  • Meshes
  • Curves
  • Surfaces
  • Metaballs
  • Text objects
  • Lattice

Because each of these are different types of object they have different types of transforms and therefore have different set of tool. Because of this each has its own section described below.

Mesh Modeling
Typically begins with a Mesh Primitive shape (e.g. circle, cube, cylinder...).
Curve Modeling
Uses control points to define the shape of the curve.
Surface Modeling
Similar to curve modeling, but instead of being limited to simple linear paths, they allow the creation of three dimensional surfaces, potentially with volume.
Metaball Modeling

Begins similarly to mesh modeling (see above), with a base shape like a cube or sphere, but instead of extruding these base shapes, these objects are clumped together to form a larger object. In order to accomplish this, the metaballs have a liquid-like quality, when two or more are brought together, they merge by smoothly rounding out the point of connection, appearing as one unified object.

This can also be a quick way to get started with a rough shape which can be converted to a mesh later.

Text Modeling
Text modeling is an easy way to create logos and to simply add text to a scene.
Modifiers are automatic operations that affect an object in a non-destructive way. With modifiers, you can perform many effects automatically that would otherwise be tedious to do manually.
