2D web icons as well as other objects are remarkable for their flexibility. This is achieved by the peculiarity of rendering them at different resolutions suitable for various output devices.
2D Icons may embody the below items:
- raster pictures (digital graphics);
- styled text as a typeset for 2D Icons;
- vector models (geometric graphics).
The above-mentioned items can be managed by 2D transformations for example rotation, scaling or angular position etc. Meshing simple models you may get more advanced ones.
2D web icons usually are not similar to the real three-dimensional objects but because of the layers technique they are able to create the illusion of all 3D characteristics like shadow, reflection or highlighting. The layers really should maintain the certain hierarchy and order carefully.
2.5D Icons
The layered 2Dicons may also be known as 2.5D models. This technology allows web designers to work with any layer without touching the others. This kind of 2D object creation is preferred by the most of the prominent graphics editors.
2.5D is a synonym to pseudo 3D. It means "two-and-a-half-dimensional" graphics. Models created with 2.5D technology look like tridimensional while in fact they are not. The featured projection depicts both front and side views.
This technology used for designing 2D icons is frequently attained by the special lighting effect. 3D illusion can be reached as a result of virtual light source to the left or to the right side and above the users monitor.
