Reference image 3d modeling technique is to help modelers speed up their modeling process by drawing over their reference images or designs accurately. With just 5 to 10 minutes to insert a reference image before starting to model a 3D object, you speeds up your production by 5 times or more! 3D modeling using reference is important and critical to achieve good 3D geometry. However it is tedious and inefficient to model by comparing between the monitor screen and your printed design. Even if you have a huge monitor, it is still not easy to space out your monitor space just to view your reference image.
