SGI: Computer Graphics

Have some time over and thought about modelling the Octane in Psubs and set up a scene and render the Octane in Otoy's Octane

I have the Octane on my desk, so I can spin it and measure, but I severly need some kind of blueprints or at least some relativly exact drawings to model it from. You know, top, front and side kind of things.

I have already started to model it, and it goes well, but there are so many quirky bends and curves that it is hard to get it right from measurements alone.

Google haven't been able to bring up anything so far, I even had a quick flick in the Octane manual in hopes of good drawings, but no luck there either.

So I would be greatly thankful if maybe someone here have some of the good stuff and might wanna share.

I can provide you wrml model of Octane from Octane demos if you're interested.

Yeah, sure! It's definitely worth a look.

You can mail it to 'jonas at edgeloop dot se'

the "at" and "dot" is of course an '@' and a '.'

Thanks alot

The models are quite detailed - it won't be easy to surpass them. I've uploaded them on dropbox in case someone else needs them:

These are Inventor models, not wrml.

Thanks a lot, unfortunately I can't import/use .iv files, none of my program I use is able to read/import that format.

.iges/.stp/.3dm/.dxf only, dangit! Not sure if buying the relatively expensive CadLoaders for Modo would help in this case.

/Edit:
Looks like Maya might be able to read .iv files. Unfortunately I don't have a license installed on this machine. Now, where is my old Maya license? lol Probably in the attic with my luck, guess I'll have to put on some clothes and go looking for it. Gah, can't find it. It probably is there somewhere inside a box among the other gazillion of boxes.

/Edit again:
.iv files is SGI Inventor files, and is not the the same as Open inventor from Autocrap. The more you learn..

dang, so may formats and most of them are just a plain text with coordinates of verticles, still incompatible tho.

I also found some models in .wrl.gz format. Maybe someone can suggest a converter.

Might have better luck with .wrl though!

Alright, later this evening. I have already shut down my Octane.

Supernice! Let's hope I can use it this time so you haven't had to go through all this in vain.

Really appreciate it ,thx

if memory serves there are some 3d format converters installed in irix by default. i think they have their own category in the toolchest even. i recall inventor support as being part of that. but if that included conversion-from capability is an entirely different question.
also if you have a version of maya installed on the octane, check the plugin manager for any inventor format plugins that are likely not autoloaded by default but may have shipped with the software.
last place i'd look is ivview. this might have the option to export into some other format long forgotten by history.

in any case these 1996-style models are likely pretty lowpoly by today's standards and a messy CAD export to boot. might not be of much use other than for volume reference. if you have the real thing on the desk why not get to work proper? shouldn't be hard to recreate in subdivs - or even booleans if you like it messy.

Thanks for your suggestions, but unfortunately right now, I have no way of setting up my SGI equipment. Severe lack of space not to mention I have all my monitors and stuff in storage until I get ore space again. Oh well.

No, no problems of recreating at all, it will be made in Pixars-SubdivisionSurface type of geometry in my ordinary style of quality, pro/commercial stuff. So no booleans here, no thank you sir

Since there is no technical drawings/blueprints, at least from what I have found, the next best thing would be a crappy model as a volume reference/measurments for where certain details should start/end etc. I will/would of course check against my real reference item backed with real measurments.

I had the day "off" so I thought I could do this quickly before working with my clients again, so lazy as I am, good reference in form of blueprints etc. would have speed things up significantly.

This is how these "crappy" models look like. You can download them directly from my Octane while it's running or i will upload them to dropbox later:

Wow, A bit lowpoly of course, but no where near as I remembered them and a whole lot more detailed. Excellent reference. Thanks A lot nongrato!! You are indeed awesome sir!

Well, actually these are shots of Inventor models, I don't remember clearly if WRML models are as good.

Ah, that might be it. But at least the WRML files will have that as a reference, and you would asume the inventor models to be pretty exact regarding relative measurments.

Once again, thanks a lot my good sir!

My pleasure! I have alot of good stuff.

attached package contains the iv files converted to obj and sidefx format

Absolutely fantastic! Thanks a lot for this!

Turned out the case part of the wrl files wouldn't convert over properly either. Only thing I know of that will convert SGI inventor files reliably is a program called Polytrans from okino. I do have an age-old licens somewhere, but only works on 32bit version of windows it seems, probably only WinXP at that.

Again, thanks a lot!



Now the question is, can I spare a couple of hours doing some fun modelling today?

Ok, the base done. Was thinking about building the internal stuff too, but since this is only for viewing/rendering purpose, i take the easy road. Modo is not a CAD program after all.

There is a small surface detail left to do, that shall match the line in the front plastic cover, but I do that when I'm there.

Base done in Psubs, but I don't do any weighting of the edges , so I guess it could be done in ordinary subdivs anyway.

no problem at all. was just a few clicks

alternatively you could template the original stuff and put a few curves on
