-
- There have been a few comments about Virtual Reality Playhouse here,
- with a general tone similar to Chris' quote above. I suggest that
- perhaps there's a little lack of perspective. Bashing the book for
- it's perceived shortcomings in the view of those in this setting is a
- bit silly, at best.
-
- I communicate with Mitchell Waite on a fairly regular basis, and while
- I wouldn't presume to speak for him, I'd like to offer my comments
- about the book, based on my impressions and understanding of the
- intentions of the book.
-
- It should be realized, first of all, that the readers and contributors
- of this newsgroup are not really the intended audience of the book.
- Criticism of "VRP" as being lightweight rather misses the point. It
- isn't an intensive analysis of the State of the Art of Virtual
- Reality, and never pretends to be as much. It's a book intended for
- the general public, for people who have a computer and a certain
- amount of curiosity about this "virtual reality" stuff they keep
- hearing about, and would like to get at least a general idea of what
- it's about. It should be pretty obvious from the title what the book's
- nature is.
-
- Most people don't have access to SGI's, Crays, Suns, or other high
- performance graphics workstations. Most people don't have access to
- the sort of interface devices considered essential to "Real VR" by
- some. Most people can't take a trip over to the lab at HITL, or
- Wright-Patterson, or Chapel Hill, or wherever, to try out the latest
- and greatest hardware.
-
- Let's move down a bit in level. Most people don't have an opportunity
- to sit down and crank up software like VREAM or WorldToolKit or Body
- Electric or whatever, software that can be used with somewhat more
- humble machinery.
-
- Most people don't have access to internet FTP. For that matter, I'm a
- little puzzled by the comment about FTP, because as far as I know only
- one of the things included on the disk is available by FTP, the glove
- code. (By the way, let's also get rid of this often-stated concept of
- internet being "free". Access to internet is not "free". At best, it's
- only somebody else paying for it, and not YOU.)
-
- For a lot of people, the book is a chance to get a general idea of
- what VR is, get some basic information, and play around with some
- software that demonstrates some ideas, using a piece of hardware that
- they _do_ have access to, a common PC. With that, they also get a
- broad overview of what the higher levels are, and some solid
- information on who is doing what at those levels so they can
- investigate further if they like. It does what it sets out to do, give
- a _glimpse_ of what "virtual reality" is, in a readily accessible way.
- There's nothing wrong with that, IMHO.
-
- Certainly, for many of the people who participate here, "Virtual
- Reality Playhouse" is slightly redundant, and lightweight. So what? I
- wouldn't expect to see a group of Formula 1 drivers standing around
- criticising a local go-kart track; I would consider it fairly useless
- to see a group of filmmakers or video directors criticising a
- public-access video operation. The point is, if you're working
- seriously in a subject, there's nothing wrong whatsoever with anything
- which gives a large number of people an easy and relatively cheap
- glimpse of the subject at some level, and increases public awareness,
- interest, and appreciation of the more serious levels of that subject.
- Quite the opposite, in fact. Something to give serious consideration.
- A little less condescension here might be a healthy thing. For a lot
- of people here, the price of "Virtual Reality Playhouse" might well be
- better spent on a powerglove or glasses, but at the same time, those
- same people might do well to recommend the book to friends who don't
- have the same awareness and involvement in all this, but do have a PC
- and a sense of curiosity about this stuff. It might not be for you,
- but it does the job it was intended to do.
-
- To bring this little editorial to a close, there's one more thing. I
- definitely consider the characterization of Nicholas Lavroff and
- Mitchell Waite's efforts as "another sad case of cashing in on other
- people's public domain efforts" to be unfair. First, let's get the
- facts correct. If I'm not mistaken, none of the included software is
- public domain. Free and public domain are not synonymous terms. Not
- meaning to pick nits, but that is a distinction that's often lost. Of
- that software, the only authors who I have any personal communication
- with are John Swenson and Dave Stampe, and I haven't seen either of
- them bitching about the inclusion of their work in the book's disk. As
- far as what has been done in the book is concerned, Nicholas Lavroff
- and The Waite Group have collected a body of concrete information,
- overview explanation, and working software, and put it on the market
- for people to pick up at the local bookstore and take home with them
- instead of having to search it all out for themselves at the expense
- of their own time and effort, at a reasonable price. That's simply
- providing a service and getting paid for doing so. I find no fault in
- that. I think doing what they have done does considerably more good
- for this field as a whole than it does to sit around posting messages
- to this newsgroup congratulating each other for being far too
- sophisticated to be impressed by such a humble little tome. Cut these
- guys a little slack.
