Type Method

geometrySourceWithVertices:count:

Creates a geometry source from an array of vertex positions.

Declaration

+ (instancetype)geometrySourceWithVertices:(const SCNVector3 *)vertices count:(NSInteger)count;

Parameters

vertices

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

count

The number of vertex positions.

Return Value

A new geometry source whose SCNGeometrySource property is SCNGeometrySourceSemanticVertex.

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 geometryWithSources:elements: method.
