thanks for pointing me in the right direction.

as always i enjoy your blog and always check in to see whats new from time to time.

it would be great for all the orthophoto sceneries developpers like me and will help both for the size adn the loading of the scenery !

By Jove, you mean, like in normal maps for aircraft textures? Woot! Although they could certainly be useful for terrain as well. Mmm…

(4-bit alpha from DXT3 is inadequate for us a lot of the time, and DXT5 limits the high frequency possibilities of the alpha channel for us in others.)

I’m dealing almost every day with DDS textures in Oblivion; even in DXT1, the compression artifacts are not a problem. The only case where an agressive compression can make a very noticeable difference is when compressing normal maps in DXT1, and I dont remember X-Plane using them anywhere in the sim.

DDS is a _file format_…in other words, it’s an agreement about how to encode data onto a hard drive. (Computer scientists, stop cringing. 🙂 So it’s not specific to Mac or PC, and doesn’t really depend on a particular computer.

THEORETICALY speaking, any file format should be POSSIBLE for any operating system.

Now a file format is useless unless you can READ the file, and that’s where the question comes: can somebody program the Mac to read this file?

In the answer of DDS the answer is: yes definitely. You don’t need DirectX to read a DDS file…you just need to write a program.

Most file formats can be supported on any operating system.
