Wireframe rendering

Wireframe renderings are less used than photorealistic ones, nevertheless from time to time this technique is still usefull.
What these kind of renderings give is the possibility to have a look at the structure of the 3d model helping to find hidden parts of the model or even see directly inside the model.
This is a nice way to have a "computer generated" appearance of the rendering.

Sometimes it's very usefull to have a model rendered as if we have been "skinning" it for example to show a part of the model with the material and textures on it and another part simply with the 3d structure enabling us to see internal elements/parts.
In these situations, wireframe rendering comes to help us with some very nice final effects.
