How do I create a Frustum as a node that I can add to a scene? For example:
var frustum = new Frustum();
var tr = scene.RootNode.CreateChildNode(frustum).Transform;
tr.Scale = new Vector3(obj.Width, obj.Height, 3); //…...Translation = new Vector3(-10, -10, -7);...Vector3(0.3, 0.3, 0.3); tr.Translation = new Vector3(-20, -20, -7);...
