Modelling with planes?

[WALP]

No this should hurt performance pretty bad I think. Having structures made of planes means drawcalls for materials and other object rendering features for every single plane, as opposed to having it all in one mesh would only need to do drawcalls for materials and such once, and not have to check for every single face/triangle.
In other words having one object that is 10000 triangles is better than having 1000 objects that are 1 triangle each, and I am pretty sure we can consider a plane to be some kind of object here.

The only performance wise reason to seperate objects is culling. Basicly it means not rendering what is not visible, so if your entire level was one object you would always have to do passes for the entire level at least to some extend, so splitting it up between rooms allows you to skip rendering some stuff.


That said as long as you dont go crazy and make a grunt out of planes and such you should be fine.
