Basic differences between 2D and 3D icons design
Speaking about 3d Icons we need to point out that the source of light plays an extremely important role for creating authentic three-dimensional images. Undoubtedly the using several light sources in website design today is more effective but take into account that they should follow fundamental rules of physics and be truthful. A few 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 means of creating this illusion. Definitely the volume can be displayed by 3D Icons to more extent than 2D Icons. More often the images are flat and present just one perspective. Detailed highlights and imperceptible soft shadows are missing as a rule. The shades usage is restricted as well.
3D icons can be proud of all these features instead. Nevertheless dont forget that 3D is nothing but mathematical replication of the data that unfortunately restricts its usage. In some cases you can easily replace 3D Icons by 2D ones or by the videos with the sounds - but all this depends on situation. The sounds give additional dimensionality to the videos that actually use 2D images.Software used for 3D modeling enables to create that 3D dimension. Don't forget that 3D icons should be depicted in correlation with the other objects and the environment they're placed into.
