Mesh.colors 顶点颜色

using UnityEngine;
using System.Collections;

public class example : MonoBehaviour {
	void Start() {
		Mesh mesh = GetComponent<MeshFilter>().mesh;
		Vector3[] vertices = mesh.vertices;
		Color[] colors = new Color[vertices.Length];
		int i = 0;
		while (i < vertices.Length) {
			colors[i] = Color.Lerp(Color.red, Color.green, vertices[i].y);
			i++;
		}
		mesh.colors = colors;
	}
}

// Sets the vertex color to be red at the y=0 and green at y=1.
// 设置顶点颜色，使y=0的顶点为红色，y=1的顶点为绿色。
// (Note that most builtin shaders don't display vertex colors, 
// （注意大多数的内置渲染器不显示顶点颜色
// you can use eg. a particle shader to see vertex colors)
// 您能使用这个例子,一个粒子渲染器来查看顶点颜色。
function Start () {
	var mesh : Mesh = GetComponentMeshFilter.mesh;
	var vertices : Vector3[] = mesh.vertices;
	var colors : Color[] = new Color[vertices.Length];

	for (var i = 0; i < vertices.Length;i++)
		colors[i] = Color.Lerp(Color.red, Color.green, vertices[i].y);

	mesh.colors = colors;
