I am impressed with where technology is taking us, and I am ready to go there.
However, I can't help but compare this to watching a movie vs reading the book.
It's a different experience, but I am not ready to say that it's a better experience.
What caught my eye was the Global Illumination images in BIMx and the Unreal Engine presentations. Why Render a scene that takes hours when a screen shot is just as good?
