MeshUtilsCalculateNormals(PositionNormalTexture, Int32, Int32, Int32, Boolean) Method

public static void CalculateNormals(
	PositionNormalTexture[] vertexBuffer,
	int[] indices,
	int startTriangleIndex,
	int indicesCount,
	bool normalize = true
)

Parameters

vertexBuffer  PositionNormalTexture

array of PositionNormalTexture that represents a vertex buffer

indices  Int32

triangle indices

startTriangleIndex  Int32

index of the first triangle index to process (note that this is not triangle index but index in the indices array so the startTriangleIndex for the second triangle is 3)

indicesCount  Int32

number of triangle indices to process (to get indicesCount from the number of triangles multiply the number of triangle by 3)

normalize  Boolean  (Optional)

when true (by default), then the normals are normalized
