How do we fill color between two raycast in unity?

Question

I created a cube with meshfilter, boxcollider, rigidbody(in 2D platform) in unity. It creates a raycast towards each of the vertices in the scene(platforms, boxes and anything having box collider with it). But, I am having a problem as how to fill a color between any two raycast I created. My game scene:-

My script:-
using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class Lights : MonoBehaviour
{
    public GameObject[] sceneObjects;
    public float offset = 0.01f;
    RaycastHit hit, hit2;
    // Start is called before the first frame update

    void Start()
    {
    }


    // Update is called once per frame
    void Update()
    {
        Vector3 myPos = this.transform.position;
        for (int i = 0 ; i< sceneObjects.Length; i++){
            Vector3[] mesh = sceneObjects[i].GetComponent <MeshFilter>().mesh.vertices;

            for (int j=0; j<mesh.Length; j++){
                    Vector3 vertiLoc = sceneObjects[i].transform.localToWorldMatrix.MultiplyPoint3x4 (mesh[j]);

                    Physics.Raycast (myPos, new Vector2 (myPos.x - vertiLoc.x - offset, myPos.y - vertiLoc.y - offset),out hit, 100);
                    Physics.Raycast (myPos, new Vector2 (myPos.x + vertiLoc.x + offset, myPos.y + vertiLoc.y + offset),out hit2, 100);
                    Debug.DrawLine (myPos, hit.point, Color.green);
                    Debug.DrawLine (myPos, hit2.point, Color.blue);
                    Debug.Log (vertiLoc);
            }

        }  

    }
