3d Floor Plan

[pax]

1. Запоминать координаты всех линий и рисовать все сразу.
2. Для каждой линии создавать отдельный объект, ее рисующий.
3. Использовать например LineRenderer
4. и т.д.

Как отредактировать этот скрипт так чтобы он рисовал не линию а прямоугольник
using UnityEngine;
using System.Collections.Generic;
public class example : MonoBehaviour {

struct line
{
public Vector3 start;
public Vector3 end;
}
public Material mat;
private Vector3 mousePos;
private bool startDraw;
private List<line> lines;
private line currentLine;
void Start() {
lines = new List<line>();
startDraw = false;
}
void Update() {
mousePos = Input.mousePosition;
if (Input.GetKeyDown(KeyCode.Space) && !startDraw)
{
currentLine.start = new Vector3(mousePos.x / Screen.width, mousePos.y / Screen.height, 0);
startDraw = true;
}else if (Input.GetKeyDown(KeyCode.Space) && startDraw)
{
currentLine.end = new Vector3(mousePos.x / Screen.width, mousePos.y / Screen.height, 0);
lines.Add(currentLine);
startDraw = false;
}

}
void OnPostRender() {
if (!mat) {
Debug.LogError("Please Assign a material on the inspector");
return;
}
GL.PushMatrix();
mat.SetPass(0);
GL.LoadOrtho();

foreach(line l in lines)
{
GL.Begin(GL.LINES);
GL.Color(Color.red);
GL.Vertex(l.start);
GL.Vertex(l.end);
GL.End();
}

if(startDraw)
{
GL.Begin(GL.LINES);
GL.Color(Color.yellow);
GL.Vertex(currentLine.start);
GL.Vertex(new Vector3(mousePos.x / Screen.width, mousePos.y / Screen.height, 0));
GL.End();
}
GL.PopMatrix();
}
}

Рисовать не линиями а треугольниками.

Привет всем!!! Подскажите пожалуйста как изменить скрипт для рисования мышью

private var origPoints : Vector2[];

function Start () {
    linePoints = new Vector2[numberOfPoints];
    origPoints = new Vector2[numberOfPoints];

    var p = 0.0;
    for (i = 0; i < numberOfPoints; i++) {
        linePoints[i] = Vector2(.5 + .25*Mathf.Cos(p), .5 + .25*Mathf.Sin(p));
        origPoints[i] = linePoints[i];
        p += radians;
    }
}

function Update () { 
    for (i = 0; i < linePoints.Length; i++) {
        if (i%2 == 0) {var m = .4; var t = 1.0;}
        else {m = .5; t = .5;}
        linePoints[i] = (origPoints[i]-Vector2(.5, .5))*(Mathf.Sin(Time.time*t)+Mathf.PI*m)+Vector2(.5, .5);
    }
