Message-Id: <2alts8$q65@wraith.cs.uow.edu.au> I have been hunting around for cyberspace protocols. I came across Michael Snoswells "Cyberterm" which was very interesting. Are there any others floating around on ftp sites?? Also, I can't seem to mail snoswell. Does anyone have his latest i'net address (if he still has an account). Also, I belive cyberterm was shareware, anyone know where I can pick it up? -- +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+- Shane Richards u9050728@cs.uow.edu.au +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+- [I'm not sure about protocol, I believe I saw a Cyberspace Manifesto floating around the 'net.

I've been toying with the idea of constructing a HMD but I have a few questions. 1) Where would one find color lcd displays used in an HMD? 2) What kind of 3-d software (public domain) is availible for testing the device. I'm also curious as to what the experts think it would cost to build a basic HMD (as I am on a limited budget). There are many more questions I might have in the future, but these should suffice for now. :) Thanks in advance, Al Dorrington -- _____________________________________________________________________________. | Al Dorrington | F/A-18 \ _ / Hornet | V107NR8D@ubmvs.cc.buffalo.edu | | Elect.

Is anyone out there already using Kubota workstations for VR? How good are they for "our" purposes? I don't want benchmark figures, just impressions from users... Does anyone know a good "point of contact" at Kubota to talk a little about these things? Thanks anyone.

My goal is to develope a graphical server for internet eventually leading into VR apps. Any help would be greatly appreciated.

Apparently it is >similar to the cyberspace< toolkit that Autodesk is working on, except >that SuperScape (in versions VRT1 VRT2 & VRT3) has been out for a few >years. I have seen Superscape several times and played with VRT2 for a few hours once. Going by comments on CDK and the technotes I would say that Superscape works at a much higher level. CDK is very much bare bones stuff and requires a lot of programming. Superscape however requires little or no programming (by programming I mean using their Superscape Command Language (?)). I saw VRT3 last week and it has been extended considerably, mainly in the SCL area and I believe in the software developers kit, a C library that allows you to do the same as SCL and more. > We are interested in creating realistic virtual places (eg an office >with textured furniture, rolodex, glass vase, etc) which we will then >animate so it looks like you are flying through (walking) on a >predetermined path.

If you want realistic rendering then Superscape won't be much use. They have added simple texturing in VRT3 but as far as I know anything that isn't textured is flat shaded. It is a pretty neat system all the same. If only the rendering were better... 3D Studio will give you good realistic renderings if you can wait. All animation in 3D Studio (I have experience in version 1.5 only) is done using keyframing which can be very time consuming depending on what you want to do. For walkthroughs specifying a path is quite simple and quick to do. You can also set 3DS running in "batch mode" to render each frame and then quickly load the images off disk to give pseudo-realtime animation. I think this is what PhotoVR does (they are in Spectrum Dynamics catalogue (?)). 3D Studio in conjunction with CDK might be more useful... Sense8 seems to fall inbetween VRT3 and CDK. Rendering depends entirely on the platform you run it on.
