Rendered mesh in Wireframe DisplayMode

The proposed solution is not natively supported and may not work in all scenarios and versions.

With the following code it's possible to have a mesh that is always drawn in Rendered even in Wireframe DisplayMode:

 

class MyRenderedMesh : Mesh
    {
        public MyRenderedMesh(Mesh another)
            : base(another)
        {
        }

        protected override void DrawWireframe(DrawParams data)
        {
            Pre(data.RenderContext);
            SetRenderedShader(data);

            Color col = Color;
            if (data.Selected)
                col = Color.Yellow;

            data.RenderContext.SetColorDiffuse(col, col);

            Draw(data);

            Post(data.RenderContext);
        }

        void SetRenderedShader(DrawParams data)
        {
            if (data.ShaderParams != null)
            {
                bool prevLighting = data.ShaderParams.Lighting;
                var prevPrimitiveType = data.ShaderParams.PrimitiveType;

                data.ShaderParams.Lighting = true;
                data.ShaderParams.PrimitiveType = shaderPrimitiveType.Polygon;

                base.SetShader(data);

                data.ShaderParams.Lighting = prevLighting;
                data.ShaderParams.PrimitiveType = prevPrimitiveType;
            }
        }

        protected override void DrawIsocurves(DrawParams data)
        {
            //base.DrawIsocurves(data);
        }

        protected override void DrawForSelection(GfxDrawForSelectionParams data)
        {
            Pre(data.RenderContext);

            base.DrawForSelection(data);

            Post(data.RenderContext);
        }           

        private static void Post(RenderContextBase context)
        {
            context.PopRasterizerState();
        }

        private void Pre(RenderContextBase context)
        {
            context.PushRasterizerState();
            context.SetState(rasterizerStateType.CCW_PolygonFill_CullFaceBack_PolygonOffset_1_1);
        }
    }

model1.Entities.Add(new MyRenderedMesh(Mesh.CreateSphere(10, 10, 10)), Color.Red);
var cone = Mesh.CreateCone(10, 0, new Point3D(20, 0, 0), new Point3D(20, 0, 20), 15);
model1.Entities.Add(cone, Color.Green);
model1.DisplayMode = displayType.Wireframe;
