Hi.

I'm Javier Abadía. I'm a software developer in Spain. Our company
develops Mission Planning Software for Air Forces.

My part is the Terrain Visualization facilities in the application. I (we) have
to develop a system that automatically gets DEMS, GeoTiffs, DFADs and
so (in many, many different formats) and generates a real-time terrain
skin (to say so in TerraVista manual words).

I think my two main problems will be:

- Making a system that works automatically, used by a non-technical user,
   and still generates useful terrains.

- Allowing quite large scale terrains as well as having a lot of detail in
there.
   (think that a plane could take off in Madrid and land in Moscow for example).

I expect to get some guidelines and advice from this list. Also I would like
to contribute to the list with useful information and experience when I can.

Let's see...


Aaadios!  (Goood Bye! :-))

Asunto: [vtp] List is Alive


Greetings VTP people,

I'm happy to announce that this mailing list is now fully subscribed and
functional.  The entire VTP recipient database has been added successfully -
there are 195 of you in 30 countries!

A payment has been sent to eGroups so that soon, no advertisements will
appear at the bottom of each message.

It's a good time now for people to introduce themselves to the list.  If you
are working on a particular geographical area, or particular subject within
the field of virtual terrain, it can be a good way to find other people like
yourself.

Your humble moderator,

Ben Discoe

Hello vtp Group;
I am new to this group,
When i saw vtp site i found it great. It is nice to be in this group.
I work on 3D programming. Especially using OpenGL. Though it is still
in progress i make a my own 3d object format. I Plan to progress in
animation in 3D. That means i have still much to learn from this group.
Wishing all group have nice and good achivements in their work and life..

Byes All

Hello!

   I'm Bryan Turner, a freelance research programmer.  I hold down a day job
at Cisco Systems working on IP Phone technologies.

   I was heavily into terrain rendering a few months back while designing a
module for my programming library.  I wrote an article on Gamasutra
describing my results.  And if ever my time returns to me, I'll finish up
the code for an extended demo.  My main interests lay in real-time
simulation as an aid to Human-Computer interfaces.  Nowadays this generally
means game programming.  I envision future operating systems making use of
the third dimension to help us understand and interact with our tools.

All of my released projects are available through my uber-bare web page:
http://www.geocities.com/gone2rave/terrain.htm

   I am currently involved in learning Networking & Distributed Computing,
which will become another module in my programming library.

And a great thank-you to Ben for all his work, your project is an
inspiration & aspiration.

Hi,

I'm Thatcher Ulrich, I'm the programmer for a small game company which is
about to release Soul Ride, a snowboarding sim for PC (see
http://soulride.com ).  Soul Ride uses USGS DEM data as the starting point
for modeling real mountains (the initial release will include Mammoth
Mountain in CA and Mt Washington in NH).

The Soul Ride engine is designed to render Continuous LOD on adaptively
sampled (quadtree) height data.  You can read more about the workings of the
LOD algorithm in the GamaSutra article linked off my personal page.  There's
free demo source code with the article as well.

I'm always interested in better ways to acquire, edit and interactively
render real-world data.

The method I'm using currently is essentially a slightly optimized version
of the algorithm in Jim Chen's paper, "Physically-Based Modeling and
Real-Time Simulation of Fluids".  There's a link to the paper on the VTP
water page.  The method is intended for heightfields, but can be generalized
by treating other geometry as localized heightfields.
There are a couple of problems in the approach I'm using, though.
  - No LOD.  I need to work out a useful way to do LOD with the Navier-Stokes
equations.
  - Volume conservation is really expensive.  At least my attempt is; the
complicated part is increasing the size of a puddle since you have to scan
the surrounding terrain to see if you grow outward or upward and the amount
you grow is volume rather than area-based.
  - Only doing incompressible 2D Navier-Stokes.  Pretty useful for surface
dynamics but doesn't deal with submerged objects and has bad behavior at
boundaries.  I'm looking into training an AI (some high-capacity neural net)
to do the full 3D Navier-Stokes in real time, but don't know yet if I can
get enough accuracy for this to be a worthwhile approach.

Hi, I was surprised by the sudden life in the group. I am doing a part-time
research project at Melbourne uni. I am visualising (there must be a better
word) a volcano erupting, and seeing how well the different VRML,
Animations, Game Engines deliver a learning point to High School students,
being a teacher I thought I might as well use my captive audience as guinea
pigs. I feel Unreal Tournament is the way to go for teaching history,geog,
sci. But Morfit is my favourite vehicle as it is free. Any suggestions about
engines that allow multiuser that are free, and that an old schoolie can
master.Yours Brian Quinn

Hello VTP group!

I am responsible for the Distributed Intel Scene Manager (aka DISM) that VTP
uses to load and display 3D. My role in the VTP project is more one of
service since my contribution is in providing a framework for VTP graphics
development.

My research topic currently is using multiple processors for parallel scene
management. This includes distributing both simulation and geometry
workloads. VTP is a potentially infinite workload which presents serious
technical challenges for load balancing and distribution across a network.

I am also working on web-enabling DISM. Right now the DISM object model is
exported via the Java Native Interface and we have ActiveX and NetScape
plugins.  I am hoping to make JNI wrappers for some of the VTP classes so
that they may be called from Java as well.

Ben is pioneering in the area of open source. I will eventually follow in
his footsteps and make the DISM source publicly available.

Thanks,

The List is Alive all right...good grief!

Since I can't get any work done, thanks to all the VTP mail flooding my
machine, I might as well say hello too ;)
My name is Mike Dickheiser, and I'm a programmer with a computer game
company in Cary, NC, called "iRock Interactive".

My primary interests/responsibilities relate to physics and collision
detection of all kinds. Additionally, I've been working on a real-time
dynamic water engine for use in our products. This is essentially a 2d
system (surface considerations only), but it's sufficient to generate
realistic looking waves, ripples, and wakes for objects moving across the
surface. It also produces really nice reflections against terrain and
anything else for which such a thing is deemed interesting.

Since I noticed a few other gamers in the list you might recall mention of
a title being produced by Interactive Magic called "Red Fury". This was the
fluid engine for that game, and was shown at E3 in Atlanta a few years back.

Anywaze, the point of all the gab is presumably the same as for others, to
introduce myself and share a few things that others might find interesting,
possibly to the extent of opening up some long-term communication lines.

So, if you're into physics, collision systems, fluid simulation, or game
programming in general, or heck, anything else, feel free to drop me an
e-line.

-Mike

I'd love to hear more about what you're trying here. Water that collects in
pools and flows in response to gravity and terrain deformation is something
that's been in the back of my mind for a while. I think with a normal
height field it should be doable, but more general geometry would be
painful (having it flow into a cave for example). At one point I had an
idea that seemed workable for a height field, but I haven't had a chance to

Hello, all.
My name is John Barstow and I'm experimenting with real-time fluid dynamics
on terrain (rivers, lakes, etc.).  I'm also working on physically-based sky
colour/clouds.
I'm based in Issaquah, WA (near Seattle), using the DEM data from the
University of Washington.

So far I have sun position and sky colour (single scattering) working in
real-time, although *something* in my calculations blows up after sunset
(night sky flashes funny colours).
Fluid dynamics constrained to fixed boundaries seems to perform reasonably
well with reasonable performance, but volume conservation (needed for
dynamic terrain and things like puddle formation) brings the system to its
knees.

I work on real-time deformable terrain rendering for Longbow Digital Arts
(signed on as Lead Programmer after Seumas passed away). Currently we're
using his CLOD scheme using bin-trees (derived from ROAM), but I'm going to
start researching VIPM for the purpose in the next couple of months. This
is mostly inspired by a port to a soon to popular console, but should be
applicable to the PC platform as well. Working on other things right now,
but hopefully I'll be able to get back onto terrain in October.

Phil,

At one point I think I heard someone claim you could derive a rough
approximation of the color of the sea based on water depth ...

Do you know of any free data on a world wide scale?  It might be
interesting first pass at varying the ocean color in my flightgear
project. :-)

I'm a programmer for Haptek Inc. in Santa Cruz California.
My main interest in VTP is rooted in natural game environments.
That said, I'm mostly interested in realistically simulating non existent

Ok, I'll take a minute to introduce myself.

My name is Curt Olson.  I work at the Human Factors Research Lab at
the University of Minnesota.  My duties primarily center around
developing and supporting our driving simulators:

     http://www.hfrl.umn.edu/

In my "spare" time I coordinate the FlightGear open source flight
simulator project:

     http://www.flightgear.org

I've been the main force behind the scenery development for this
project.  My work has mainly focused on developing a set of automated
tools to transform raw data into final scenery.  I can regenerate the
entire world in about 5 hours using a set of 25 linux machines to
distribute the work.

I think much of what I've done or am doing parallels what is going on
with vtp, although we are concentrating on a specific "slice" of
terrain/scenery generation approaches.  Our concern is real time
rendering performance and levels of detail appropriate for flight
simulation.

Currently I'm working on code to automatically build airports based on
an extensive airport/runway database.  This is tedious work, but beats
doing it by hand in some modeling program for every airport out
there... :-) Obviously we sacrifice some detail/reality by working
from a database, but the goal is to eventually allow people to hand
tweak areas to add additional detail.

We have a web site setup for the terrain generation / 3d mapping
portion of the flightgear project:

     http://www.terragear.org/

It's rather sparse at the moment, but it all our code developed to
date is available there.

A potentially interesting spinoff from the flightgear project is a
moving map program called atlas:

     http://atlas.sourceforge.net/

This package can generate bitmaps directly from the FlightGear scenery
and then tile them together in a moving map display.  It overlay
runways and navaids in real time.  You can zoom in/out attach your
(real) gps via a serial port, or talk via network to a running copy of
FlightGear to display your current position and surroundings.  Obvious
disclaimer that I wish wasn't necessary to include: we are using free
non-validate, non-current data so it would be illegal, not to mention
*really* stupid to try to use this to navigate your airplane someplace
in real life.  You don't want to break out of the clouds at 100' agl,
realize you are 1/2 mile off from where the runway really is and find
your self dead center lined up with a water tower or something. :-)

I love to discuss flight simulators and terrain generation. :-)

Curt.

Hi All!

My name is Cassandra Thomas and I am in California. I am very interested in
the idea of temporal models of geographic areas, i.e. modeling how areas
change over time. This interest in extending VTP temporally grows out of my
interest in the environment and urban planning. I also like to model with 3d
studio (very easy to insert culture into Max...i feel a VTP F.A.Q. coming
on) and I love using Xfrog (www.greenworks.de) to work on plants! My
programming skills are minimal but growing - by day, i am a web usability
consultant). I currently work on Virtual Hawaii when I have time but I am
also am interested in modeling New Orleans concentrating on historical
change in the French Quarter. Anyone from that area? Anyone not mind a few
house guests?

Greetings VTP people,

I'm happy to announce that this mailing list is now fully subscribed and
functional.  The entire VTP recipient database has been added successfully -
there are 195 of you in 30 countries!

A payment has been sent to eGroups so that soon, no advertisements will
appear at the bottom of each message.

It's a good time now for people to introduce themselves to the list.  If you
are working on a particular geographical area, or particular subject within
the field of virtual terrain, it can be a good way to find other people like
yourself.

Your humble moderator,

Ben Discoe

Well, this is my first post on VTP eGroup.
I started to work on VTP 5 months ago but got very busy the last
couple of months and didn't really follow the progress of VTP.
Now, with this new forum, I think I'll get more involved in this
project that I'm still highly interested to.
I even forecasted a VTP section on my web site that I planned to
develop sometime soon.
Anyway, thanks to contact me and to keep me informed on the project.
Thanks to Ben Discoe too.
Jean-Louis
