Initializer

init(vertices:)

Creates a geometry source from an array of vertex positions.

Declaration

@nonobjc convenience init(vertices: [SCNVector3])

Parameters

vertices

An array of three-component vectors, each of which represents a vertex position for the geometry source.

Return Value

A new geometry source whose semantic property is vertex.

Discussion

SceneKit converts this data to its own format to optimize rendering performance. To read the converted data, examine the properties of the created SCNGeometrySource object.

To create a custom SCNGeometry object from the geometry source, use the init(sources:elements:) method.
