No parameter needed, wie just override the vertex shader

Vertex Data Packing
Currently the terrain uses up a lot of memory. This could be the cause for all the lag spikes when rendering the world.
One optimization is reducing the amount of data each vertex holds by packing multiple attributes into one number and extracting the individual values in a vertex shader, adding a little overhead to every render.
The following plan is based on the Information Theory class from ZHAW:
