I have created a sample how to create 3D-preview of business card using Graphics Mill. You can find a sample rendering bellow.

Code:
        private void button1_Click(object sender, EventArgs e)
        {
            CreateBusinessCardPreview(@"C:\template.psd", @"C:\result.png";
        }


        private void CreateBusinessCardPreview(string sourcePath, string destPath)
        {
            //Inititally we draw on image of large size for better quality
            var size = 1000f;
            var pileHeight = size * 0.08f;
            var card1Left = size * 0.05f;
            var card2Top = size * 0.2f;
            var resultBgColor = new Aurigma.GraphicsMill.RgbColor(55, 55, 55, 255);
            var pileFoldColor = System.Drawing.Color.FromArgb(255, 210, 210, 210);

            System.Drawing.PointF[] card1Shape = {
                new System.Drawing.PointF(size * 0.222f, 0f),
                new System.Drawing.PointF(0f, size * 0.31f),
                new System.Drawing.PointF(size * 0.871f, size * 0.53f),
                new System.Drawing.PointF(size, size * 0.166f)
            };

            System.Drawing.PointF[] card2Shape = {
                new System.Drawing.PointF(size * 0.163f, 0f),
                new System.Drawing.PointF(0f, size * 0.444f),
                new System.Drawing.PointF(size * 0.9f, size * 0.652f),
                new System.Drawing.PointF(size, size * 0.16f)
            };

            System.Drawing.PointF[] pileShape = {
                new System.Drawing.PointF(card1Shape[1].X + card1Left, card1Shape[1].Y),

                new System.Drawing.PointF(card1Shape[3].X + card1Left, card1Shape[3].Y),
                new System.Drawing.PointF(card1Shape[3].X + card1Left, card1Shape[3].Y + pileHeight),
                new System.Drawing.PointF(card1Shape[2].X + card1Left, card1Shape[2].Y + pileHeight),
                new System.Drawing.PointF(card1Shape[1].X + card1Left, card1Shape[1].Y + pileHeight)
            };

            float[] pileOffsets = { 0.12f, 0.24f, 0.3f, 0.41f, 0.56f, 0.6f, 0.72f, 0.88f, 0.92f};

            int resultWidth = (int)(Math.Ceiling(card1Shape[3].X + card1Left));
            int resultHeight = (int)(Math.Ceiling(card2Shape[2].Y + card2Top));
