3-d floors provide amazing images, all of which are 3-dimensional. The pictures are then coated in epoxy resin. When choosing your image, make sure it is high resolution, you do not want it to be blurred and ruin the effect. Choosing the correct size image is also important, once the 3D epoxy flooring is complete, it should provide a realistic final image.
The 3D flooring designs are completely up to you, almost any image should work on the floor. The main thing to consider and have correct is the angle as well as the resolution of the image. If you do get a professional in, you can choose the images they provide. Some companies only do their own images, while others also allow you to choose your own. Of course, when doing DIY epoxy floors, you get to choose your own designs and images.
