What it takes for better graphics


since 10 Aug 2002
The next time you wish that Trainz had better graphics, have a look at this video which gives an inside the GPU view of what needs to happen to put the image on your screen. Luckily they use a train engine as an example so it is easy to relate.

After I watched, all I can say is wow, that GPU sure has to work for it all happen.
That video summarised much of what I have learned or deduced during the last 14 years of content creation. I especially liked the description of the Z buffer to discard triangles (and their pixels) that should not be rendered. I've always wondered about that.
Thanks for sharing.
