  1. I'm learning OpenTK for some simple 3D work. I'm able to setup a simple scene showing basic shapes. However OpenTK does not have a project() function to allow me to place 2D text into a 3D scene. I'm attempting to use the following project() function but getting odd results. Private Function Project13(world As Vector3) As Vector3 Dim view(4) As Integer Dim model(16) As Double Dim proj(16) As Double Dim Screen As Vector3 GL.GetInteger(GetPName.Viewport, view) GL.GetDouble(GetPName.ModelviewMatrix, model) GL.GetDouble(GetPName.ProjectionMatrix, proj) OpenTK.Graphics.Glu.Project(world, model, proj, view, Screen) Screen.Y = GlControl1.Height - Screen.Y Console.WriteLine(Screen.ToString) Return Screen End Function 3D math isn't my strong point, but can anyone suggest what might be amiss?
