I am more less familiarized with the major computer graphics concepts up to certain dregree of "low-levelness". So I know how models, vertices, polygons etc. and how these works. Also how is the info in these (meaning the models) serialized and interpreted by a software, generally a game or graphics engine, to use this models info, vertices and indices, to get the model itself and handle it accordingly.
Thats why I was surprised when I found some wireframe models, because I am not familiar neither with the concept nor the purpose of these.
1.- Are these handled (seralized and de-serialized) same as regular vertices models? Back in the beginning of computer graphics guess this was about all a computer could easily do, but is there any other purpose?
2.- If there is a wireframe resource provided such as this, how it would me used/handled. In the case of a 2D isometric view game, I do not know what would I need to do with resources provided in this format. What would be roughly the approach? There are no vertices in this case, the wireframe is provided as a sprite resource, so what is it that needs to be done roughly to make use of it?
I am not after an specific algorithm to handle this, this is not a code question. I mean what would be the general concept/workflow for this type of resource.
