Concept / Polygonal modeling

Polygonal modeling

A 3D modeling method that edits vertices, edges, and faces

A 3D modeling method that edits vertices, edges, and faces.

A phrase to start with

Directs form toward a 3D mesh based on faces and edges.

Appearance and effects

Faces and edges organize the three-dimensional form.

Visual traits

  • Faces
  • Edges
  • Mesh structure

Expected changes

  • Face structure is more likely to be legible
  • Form is more likely to be assembled as a mesh

Meaning and scope

Definition

Polygonal modeling creates 3D form by adding, moving, and subdividing meshes of vertices, edges, and faces. It does not include rendering, materials, or polygon patterns on an image.

In more detail

Face placement and edge flow can build forms from angular to smooth. Face count and smoothness can be adjusted separately. It is distinct from voxel grids and curve-surface methods.

Includes

  • Mesh shaping by editing vertices
  • edges
  • and faces

Excludes

  • Image creation through light
  • Voxel grids
  • Two-dimensional polygon patterns

What this does not imply

  • A specific face count
  • Material
  • Lighting

Variability

Face count and smoothness can be adjusted separately.

Usage and adjustments

Usage

  • Construct form with vertices and faces

Distinguish similar expressions

  • Specify rendering separately

Typical uses

  • Create 3D form with a mesh

Possible failure modes

  • It becomes a line-only wireframe
  • Only the pattern becomes polygonal
