OK, enough of that, the plg format and how this wireframe engine works should be pretty clear by now. 
Next installment will be to load up more than one object model and explore another way to get the model data to our renderer using the TCRenderlist4D class. After a few example projects with this approach, we’ll be adding some lights to our engine. Up to now, we have been mostly ignoring color aspects of our models. So, please stay tuned!
