   Problem with Managed DirectX 9.0 PerspectiveOffCenterLH
  I have same problems with representing object http://www.shalbarov.front.ru/untitled03.jpgMay be problem in PerspectiveOffCenterLH device.Transform.Projection = Matrix.PerspectiveOffCenterLH(0.0f,this.Width,0.0f,this.Height-    panel1.Height,0.005f, 500.0f ); 
  That, is an extra, uninitialized vertex. Your vertex information is wrong, not your viewport. ;  I create mesh like thismeshSphere =  Mesh.Sphere(dev,20.0f,20,20);what i must doing?
