[VertexElementSmoothingGroup class A smoothing group is a group of polygons in a polygon mesh which should appear to form a smooth surface. Some early 3d modeling software like 3D studio max for DOS used smoothing group to void storing normal vector for each mesh vertex. public class VertexElementSmoothingGroup : VertexElementIntsTemplate Constructors Name Description VertexElementSmoothingGroup() Initializes a new instance of the VertexElementSmoothingGroup class. Properties Name Description Data { get; } Gets the vertex data Indices { get; } Gets the indices data MappingMode { get; set; } Gets or sets how the element is mapped. Name { get; set; } Gets or sets the name. ReferenceMode { get; set; } Gets or sets how the element is referenced. VertexElementType { get; } Gets the type of the VertexElement Methods Name Description override Clear() Removes all elements from the direct and the index arrays. CopyTo(VertexElementIntsTemplate) Copies data to specified element SetData(int[]) Load data SetIndices(int[]) Load indices override ToString() String representation of vertex element.
