# [name]

Contains handy functions geometry manipulations.

## Methods

### .merge( [page:Geometry geometry1] , [page:Geometry geometry2], [page:Integer materialIndexOffset] )

geometry1 — Parent geometry element
geometry2 — Geometry that need to be added in parent
materialIndexOffset — Offset applied to the materialIndex of all the new faces in the merged geometry. Default : 0

### .randomPointInTriangle( [page:Vector VectorA] , [page:Vector VectorB] , [page:Vector VectorC])

VectorA — Vector
VectorB — Vector
VectorC — Vector
returns [page:Int Point]

### .center ( [page:Vector VectorA] , [page:Vector VectorB] , [page:Vector VectorC])

VectorA — Vector
VectorB — Vector
VectorC — Vector
returns [page:Int Area]

### .center ( [page:Geometry geometry] )

Geometry — Geometry to Center position
