Call programs like paint to create images?
Did you learn to code on this planet?
Generating a complex mesh like that bridge, well that's just incredible, in fact I'd be surprised if it didn't have some designed mesh elements, like prefab bits that it re-uses a lot rather than working out all the polygons itself.
I'm guessing the textures are created like fractals, they might have control over colouring and noise and suchlike - that's doable in DBPro, and not something that anyone would do in Paint, they'd be generated as raw images in code.
There's no doubt that DBPro could make a cool demo like that, the cube snakes for example are quite straightforward and could be replicated to make a cool effect. Same goes for the cube that comes apart, probably be able to get something like that in DBPro as well.
