Class VertexAttribute

java.lang.Object

com.codename1.gpu.VertexAttribute

public final class VertexAttribute
extends Object

Describes a single attribute (position, normal, texture coordinate, color) within a VertexFormat. The engine derives the generated shader's vertex inputs from the attributes present in the format, which is why a fixed set of well known usages is used rather than free form names.
