public class MeshSpecification
extends Object

java.lang.Object
↳	android.graphics.MeshSpecification

Class responsible for holding specifications for Mesh creations. This class generates a MeshSpecification via the Make method, where multiple parameters to set up the mesh are supplied, including attributes, vertex stride, varyings, and vertex/fragment shaders. There are also additional methods to provide an optional ColorSpace as well as an alpha type. Note that there are several limitations on various mesh specifications: 1. The max amount of attributes allowed is 8. 2. The offset alignment length is 4 bytes. 2. The max stride length is 1024. 3. The max amount of varyings is 6. These should be kept in mind when generating a mesh specification, as exceeding them will lead to errors.
