Basic differences between 2D and 3D icons design
Speaking about 3d Icons we should point out that the source of light plays an extremely essential role for creating authentic three-dimensional images. It is appropriate and even recommended to use several light sources in internet site design nowadays however they should follow basic rules of physics and be truthful. So if you need to make 3D web icons look softer and more realistic - use several lights.
The purpose of 2D and 3D icons is to represent the volume found in the three-dimensional world but 2D and 3D icons obtain this illusion working with different means. 2D Icons can surely represent volume to less extent than 3D Icons. Usually the images are flat and present just one perspective. Detailed highlights and imperceptible soft shadows are missing as a rule. The shades usage is limited as well.
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 cases you can effortlessly replace 3D Icons by 2D ones or by the videos with the sounds - but all this depends on situation. The sounds give some extra dimensionality to the videos that actually use 2D images.Software used for 3D modeling enables to make that 3D dimension. It is very important show 3D icons in correlation with the other objects in the neighborhood and the environment they are placed into.
