Decals
By Alan Baylis 13/03/2002
The decals used in this demo are based on the method used by
Nate Miller and you should have a read of his tutorial if you haven't already done so. I found that there were two different rendering styles needed to render different types of decals (bullet holes or burn marks) and the program demonstrates both. This type of decal would most likely be described as a first generation type as they are not clipped and do not cover multiple faces.
There is surprisingly little (free) information about decals on the net which may be due to the fact that they are relatively new. The newest method is called 'decal mapping' and I have a fair idea of how it is done but will wait until I find at least one example/explanation of the method before I give it a go.
