GraphicsComplex

GraphicsComplex[{pt1,pt2,…},data]

represents a graphics complex in which coordinates given as integers i in graphics primitives in data are taken to be pti.

Basic Examples  (3)

Polygons and lines in 2D:

Polygons and lines in 3D:

Use built-in PolyhedronData:

Do the same using PolyhedronData property annotations:

Scope  (3)

The coordinate data for any primitive can come from a GraphicsComplex:

3D primitives:

Mixing directives and primitives within a GraphicsComplex:

Options  (7)

ContentSelectable  (3)

No individual object is selectable; the graphics complex appears as one object:

Allow the individual objects in the graphics complex to be selectable by a single click:

The first click selects the whole complex, and subsequent clicks select individual objects:

VertexColors  (2)

Specify colors for each vertex:

Specify vertex colors for 3D polygons:

VertexNormals  (1)

Define vertices and face indices of a cylindrical model:

Without surface normals, the shading is constant or flat for each polygon face:

With surface normals, the shading is interpolated or smooth across each polygon face:

VertexTextureCoordinates  (1)

Texture mapping with 2D polygons:

Texture mapping with 3D polygons:

Applications  (2)

Most surface and region plots produce GraphicsComplex:

You can use GraphicsComplex to transform the coordinates in this simple rotation:

The same idea applies to 3D surfaces:

Properties & Relations  (4)

Set up a graphics complex with shared coordinates:

Applying Normal will split a complex into primitives with duplicated coordinates:

Both forms produce the same image:

Graphics complexes can be built up from integrated PolyhedronData:

Or, get a graphics complex directly:

ExampleData contains a number of 3D graphics complex models:

Many Import formats produce GraphicsComplex:

In this case the surface has about 35000 vertices:
