Hello,
I am a new user of Celestia.
I would like to know how to transform starting from an format JPEG or PNG picture into an dds format.
Which software it is necessary to use to do that?
How to create several pictures dds format of 512*512 of one only kid picture of 2048*1024?
Thank you.
Need your help about DDS format

Hi Izar1,
This is what I've used; jpeg or png to bmp in Paint (or other similar apps), then dxtex.exe (Microsoft) available as utility in Orbiter space sim (free download) and elsewhere probably, for dds conversion from power of 2 size bmp only. So either manually resize and chop a bmp into 512 squares using Paint etc, or have a look at virtualtex threads on this forum for an automated method. Depends on how much you need to do/how often/ how interested/good at/patient with etc. If you just want to put a close up picture in at a location or something relatively simple like that, above is ok. To name your dds tiles so that they are in the right place use the excellent excel script that has been posted here recently. This works with the spreadsheet app. in Open Office, so you can do it all for free.
I think Irfanview has a plug in that will save to dds , but I'm not sure, I'm sure there are better answers for you , but I didnt want you to feel ignored, all the best , Z

For conversion to DDS and reverse I use Nvidea's tools:
- nvdxt: a comandline tool (nice for batch conversion)
- PSD / PSP filter plugin
http://developer.nvidia.com/object/nv_t ... tools.html
To view dds files or for back conversion you can also use "Irfanview" or "XnView".
To cut a map into small tiles that means to build a virtual texture you can find several sripts on the forum. At the beginning you should start here:
