File formats - DDS conversion tools?

Post #1by rthorvald » 28.05.2004, 11:17

It seems to me that the DDS format is much more memory-effective than others: i have no problems displaying a 32k DDS VT, while an 8k JPG VT gives me display problems if i have more than one body in view. The DDS also loads much faster.

I have done an extensive search after a conversion tool that makes DDS files out of more regular graphics formats, but cannot find _anything_ that can write DDS files in OSX. Grapphicconverter should supposedly READ them, but that does not help if it can?t?export.

Does anyone know? An alternative could be a very lightweight windows tool (i can run it in VirtualPC).

Many people use the Windows program nvdxt.
See http://developer.nvidia.com/object/nv_texture_tools.html

Nvidia also provides a Photoshop plugin on that same Web page. I don't know if it's usable with Mac paint programs.

Well, the Nvidia command line tools won?t run on my WinXP for some reason, and the Photoshop plugin only works with the Win version - i only have it for Mac.

But thanks, anyway.

What about the GIMP - does it have a DDS export plugin, anyone? Have looked, but not found...

Not sure about the MacOS X support, but maybe DevIL could help:
http://openil.sourceforge.net/
It's actually a image library, but there are some example programs, one of which can be used to convert to DDS.

Based on the latest CVS version of DevIL, and after eliminating further bugs, I coded some time ago a quite versatile conversion programme. It converts about anything into DXT 1,3,5 and resizes (automatically), sharpens and automatically cooks a meal during the conversion process;-)

I gave the sources to some people before...

But of course, users must be able to compile for themselves. It runs under Linux, Cygwin and presumably native Windows with the DevIL libs installed, of course.

It is "lightening fast" (unlike the NVIDIA tools!) and does not have this incredible <16k limitation.

fridger - your english is really bad, signing off "bye fridger" sounds like your telling yourself byebye - it doesn't make any sense.

do you have no life!!! - you seem to post all the time in these forums - get out into the fresh air.

and stop being so arrogant as if you're so much cleverer (therefore better) than everyone else.

I?m afraid that sounds more like magic than tech to me... But thank you, anyway :-)

Presumably, your german is much better. And, if you have something to say, please use your name. Btw, Fridger is one of the reasons you have this great program to play with.
