2D and 3D icons comparative analysis
As for the 3d Icons the light source plays important role for creating authentic three-dimensional images. It is appropriate and even recommended to use several light sources in website design today however they should follow basic rules of physics and be truthful. Several lights usually make 3D web icons look softer and more realistic.
Both 2D and 3D icons represent the volume found in the three-dimensional world but use various ways of creating this illusion. 2D Icons can certainly represent volume to less extent than 3D Icons. One of the disadvantages of 2D Icons are flat images that show just one perspective. To this weakness you can add one more - detailed highlights and imperceptible soft shadows are missing. Also the shades usage is really limited.
3D web icons can be proud of all these features instead. But 3D is mathematical replication of the data which anyway limits its usage. In some case 3D objects like 3D Icons may be successfully replaced by 2D ones or by the videos with the sounds. 3D dimension can be created due to the software used for 3D modeling. It is very important depict 3D icons in correlation with the other objects in the neighborhood and the environment they are placed into.
