Points Convertion

Unity Engine
1

I have a software that comunicates with a Unity3D module that I’m developing and passes an image and a list of Points. The points should be correctly placed on top of the image, but they are not. I’ve seen code samples that look into this problem, but none of the ones I tried works (the one I place here is actually one of them)

I place an image here as example of what I need to accomplish. In the image the “sphereCollider” that are seen (marked with a red circle) should be on top of the circles connected by the lines.

Does anyone knows how to solve this conversion problem?
My thanks in advanced

This is my code.

public void DrawOnScreen()
{
SphereCollider sphereCollider;
Vector3 v3Converted;
Vector3 v3ConvertedToWorldUnits;

Camera cam;

cam =GameObject.Find(“MainCamera”).camera;

foreach (Script_Ponto pt in LPt) {
sph=GameObject.CreatePrimitive(PrimitiveType.Sphere);
v3Converted=new Vector3(pt.PontoX,pt.PontoY,0);

v3ConvertedToWorldUnits=cam.WorldToScreenPoint(v3Converted);

sph.transform.position=v3ConvertedToWorldUnits;
sph.transform.localScale=new Vector3(4,4,4);

Debug.Log(“SPHERE x:” + sph.transform.position.x + " y:" + sph.transform.position.y + " z:" + sph.transform.position.z);
sphereCollider=sph.GetComponent();
sphereCollider.radius=SPHERESIZE;

gObj.Add(sph);

}
}

You are converting the positions to screen space.
Is the picture in screen space?

Thank you for your answer.
Well, the picture wasn’t in screen space. I don’t know if that was the only problem since I now have other issues, after

converting the image to screen space, but looks like you may have solved the problem. Many thanks
