Topology

In 3D modeling, the term topology refers to a 3D model’s edge distribution and structure. Two models that look the same when rendered can have very different topologies.

Topologies Example

The same shape with two different topologies (left - mostly quads, right - only triangles)

Topology affects many aspects of 3D modeling and rendering, including:

• How highlights react to the model.
• How easy it is to edit the model’s shape.
• How easy it is to apply or edit mapping. Unwrapped UVs are easier to manage with quad topology.
• How easy it is to rig and animate the model. Quad topology makes it much easier to rig and animate.
