Used by TMeshObject facegroups property to access vertices for a given texture. For example its possible to get all the vertices for the meshes that uses the material 'right_leg.jpg'. Each facegroup has a material name and a vertexindices property (TIntegerList) which lists all the vertices in the TMeshObject that are in the TFaceGroup.

Important TFaceGroups properties and methods include:

items [Index: integer]: TFaceGroup List of the facegroups that make up the mesh

clear Delete all facegroups

count The number of facegroups

materiallibrary : TGLMaterialLibrary The material library used by the facegroups

Unit: GLVectorFileObjects

Descends from TPersistentObjectList.
