Vertices scaling. Area of a polygon

[sirio21]

Hi, i’d imported a mesh and i can access to vertices, but when shape is scaled vertices are same. So i need to multiply transform matrix (i think) in order to get new values of vertices in space world.

GameObject go = GameObject.Find(“triangle1”);
Mesh mesh = go.transform.GetComponent().mesh;
list = mesh.vertices;

At this point list are same if object are scaled or not

Vector3[ ] poly = GetComponent().mesh.vertices;

float x = transform.localScale.x;
float y = transform.localScale.y;

float s = poly[0].y * y * (poly[poly.Length - 1].xx - poly[1].xx);
for (int i = 1; i < poly.Length; i++)
s += poly_.y y (poly[i - 1].xx - poly[(i + 1) % poly.Length].xx);_
Debug.Log(Mathf.Abs(s / 2).ToString(“F2”));[/QUOTE]
I use “x,y” to take localScale value and mul by each vertice. I dont know if it best way (faster) to do it.

Unity - Scripting API: Transform.TransformPoint

Probably what you want.
