Declaration
+ (instancetype)geometrySourceWithNormals:(const SCNVector3 *)normals count:(NSInteger)count;
Parameters
normalsAn array of three-component vectors, each of which represents a surface normal for the geometry source.
countThe number of normal vectors.
Return Value
A new geometry source whose SCNGeometry property is SCNGeometry.
Discussion
SceneKit converts this data to its own format to optimize rendering performance. To read the converted data, examine the properties of the created SCNGeometry object.
To create a custom SCNGeometry object from the geometry source, use the geometry method.
