Class VertexAttributes

java.lang.Object

com.badlogic.gdx.graphics.VertexAttributes

All Implemented Interfaces:

Comparable<VertexAttributes>, Iterable<VertexAttribute>

public final class VertexAttributes
extends Object
implements Iterable<VertexAttribute>, Comparable<VertexAttributes>

Instances of this class specify the vertex attributes of a mesh. VertexAttributes are used by Mesh instances to define its vertex structure. Vertex attributes have an order. The order is specified by the order they are added to this class.
