Unity3d-mesh Create

Mesh needs to be created in code.

Using unityengine;using system.collections;using Unityeditor;public class Createmesh:monobehaviour {//Vertex collection Priva    Te vector3[] vertices = new vector3[constnumber.pointsum]; Triangle index Altogether (constnumber.xlength-1) * (constnumber.ylength-1) of rectangles, each rectangle 6 points private int[] triangles = new INT[6 * (Con    STNUMBER.XLENGTH-1) * (constnumber.ylength-1)]; Private color[] Colors = new color[constnumber.pointsum];//Use this for initializationvoid Start () {Createme    Shfun ();}        public void Createmeshfun () {Mesh mesh = new Mesh ();        Mesh = Createmeshobject ();        Assetdatabase.createasset (Mesh, "assets/" + "pollutant" + ".

Will grow into a rectangular mesh with a xlength width of ylength

OK, drag in, hierarchy panel, get Gameobject

Mesh creation is complete.
