MODELLING

When we think about modelling, the first thing it comes to me is a picture formed by small polygons, but what is it?

That is a type of modelling, yes it is, but modelling is not only that. Is to render a real or only existing in computer prototype, so that we could change the initial status to another new one to create a movement. We first make a data structure to render the object, then create the object on the computer to afterwards have the opportunity to edit it.

This process can be made by different methods but the most popular is the named previously: polygonal representation. Polygons, which are defined in a certain position, define the shape of the object and they can be textured. Not only that, we can move them coordinately so that it seems to be moving. However, it requires a lot of information about the positioning , the shape and the texture of each polygon.

To sum up, I should say that this is a really complex technique to model your object, the goal you have formed in a computer for applying any change after.
