Does anyone know of a conversion program for the PC that will convert Silicon Graphics native .RGB files to Targa files. I found one for the Mac but nothing on PC. Any help would be appreciated. -Parris

Parris, >> Does anyone know of a conversion program for the PC that will convert Silicon Graphics native .RGB files to Targa files. << image alchemy will convert .sgi files to anything you like. There's a shareware version available called imgalc.zip (go graphff – graphics file finder). The shareware version is crippled to images of 640×480 or less. Worked well for me – I bought the commercial version.

Conversion Artist will do it. I use it very often. Its batch processing is quick and its depth conversions (anything from monochrome to 32 bit) are very flexible. CA is very good as a basic image processor. As I recall it's less than $50 – chains like Egghead carry it. The program has been bullet-proof for me – I highly recommend it. Cheers, John

John, >>Conversion Artist will do it. I use it very often<< Next time I'm at Egghead or CompUSA I'll look for it. I've always used HiJaak but this time it's let me down. -Parris

I'm not positive, but I think Elastic Reality has programs that will do this. I believe my Exabyte/Abekas driver does .rgb conversion – but it's made for streaming to exabyte, not just file conversion =-( John Tissavary (LUNA cie, inc)

John, Thanks for the info. From the responses I've gotten so far – there is Image Alchemy and Conversion Artist to check out. Sounds like I won't have too much problem getting my files converted. Most of my work is forensic so I don't really need D1 quality– so I've got no excuse to buy the Exabyte drivers. Yet. -Parris

Parris, I see you already got some suggestions for PC conversion software. Is there some reason you can't use SGI's supplied RGB2TGA utility and convert on the SGI first? Kevin Krell – Computer Support Associates

Kevin, >> I see you already got some suggestions for PC conversion software. Is there some reason you can't use SGI's supplied RGB2TGA utility and convert on the SGI first?<< Well actually I did not know that there was a RGB2TGA utility. I have converted to tiff on the SGI and then copied it over to a PC, however the problem is that the tiff file is soooooo much larger than the RGB file. It won't fit on a floppy, and I haven't networked the SGI to the PCs. Which brings up the point–what does it cost to do that? I guess I have to get NFS for the SGI and then use Artisoft TC/IP to network to the PCs (which are running Lantastic 5.0). Also, are processor upgrades still outrageously expensive? We have a 50mhz r4000 Indigo. I know they have cpu's that are a lot faster….but at what price? –Parris

IRIX comes with NFS, so you should already have it. I'm about to set up the same sort of network, but will just be using TCP/IP and FTP'ing the files across, since I won't really be sharing other types of resources accross platforms anytime soon. Lantastic's gateway runs @ $1200 for a 5 user pack, or $300 per node. As I said, your SGI ought to have all the ingredients already, mine does. John Tissavary | LUNA cie, inc

John, I'll have to check on the NFS on my Indigo. I remember when I bought it that they wanted to sell me NFS, but that might have been for the PC. Anyway, thank you very much for your input. I don't know a lot about networks, but I'm learning fast. -Parris

Parris: Instead of Lantastic, why not just get PC-NFS for the PCs to talk NFS to the SGI? Works great, and, IMHO, is a _much_ better solution than Lantastic? That's basically what we are running here with no problems. Greg Pyros

Greg: You're probably right about PC-NFS. However I have 20 PCs here, of which only 6 are used for graphics (i.e. 3DS). The non-graphics people like the windows interface of Lantastic and probably won't want to change. All I want to do is occasionally convert some .RGB files and send them to my PC so that I can dump them to the PAR. The key here is to do this a cheaply as possible. Right now I can transfer by tape, but I thought it would be a lot nicer to do it over the network. I'll keep NFS in mind if I can afford it. Anyway, today I got a letter from SGI saying they've nixed the Indigo R4000/R4400 series and that future support will be limited. Only two years old and already an antique! -Parris

Paris, The original Indigo line has been deleted off the SGI price list, so let me check on upgrade or trade-in offers. NFS for IRIX lists for $595, and PC-NFS can be used to talk to it. BTW, in case you're not hanging out in the ACAD forum, AutoCAD R13 is delayed until November 28, when both DOS and Windows versions are expected to ship. Kevin Krell – Computer Support Associates
