Nevertheless sometimes advantages can be changed into problems. As an example the thoroughness and truthfulness of the picture may be the weakness of 3D icons. This means you are much more free to use artistic vision while drawing some object. Let's take a mobile-phone for example. So its possible to draw it rather similar to a real one but eliminate some extra details, shades and highlights. However, your consciousness discerns it as a phone easily. Often schematic drawings work even better than 3D models. You should analyze each particular situation. To develop an object and make it seem closer to real one 3d icons must repeat very carefully each detail and line. So it's more a kind of technical representation than a piece of art. Though some illustrators manage to create abstract 3D web icons that involve innovative thought and look like true works of art. Realistic and accurate modeling is the most well-known trend of 3D design today.If you're going to use some characters as icons, 3D icons are going to appear more realistic than 2D ones. The characters may remain cartoonish and this will give zest to your website.
Let us enumerate the technical issues you may face while using 3D icons.
So take note of these useful facts while creating the icons design for your website:
It is not possible to show all the glory and details of 3d icons with very poor resolution of the viewers screens;
since the monitor screen is 2D device it won't display the true three-dimensional object as we see it in reality;
3D space is harder to be manipulated and managed in comparison with 2D one;
sometimes users have to download and install some extra software that is needed for correct viewing of 3D web Icons.
In conclusion we can say that both 2D and 3D icons are based on geometric data but 3D objects are the sculpture models, they are more complicated items. And the requirements for creating the high quality 3D web Icons are much severer. 3D icons may lack creativity and abstract air but the facts of depth and volume which are effectively produced with 3D technology are incontestable.
