Hi all,

For 2 years now, we have developed a 3D rendering algorithm that is beating the
existing solutions
in volume, near-to-far ability, and accuracy hands down (classes above Google
Earth).

take a look at sample screen-shots and compare for yourself,

http://render.parvan.net/taste-test/

My sample demo spans the West US from Northern Oregon to Southern California,
from the Pacific half
way across Washington State all in the same scene and at frame rates of 10 to
100 per second on a
laptop. The engine is efficient enough to pack and deliver all 50 Billion x,y,z
points across the
US public data set.

I think we are efficient enough to actually be able to put the 3D rendering onto
a handheld GPS. I
wanted to gage everyone's interest.

1. Would you buy a gps because it had this feature over another.
2. How much extra would you pay?
3. What if it cut your battery life in half?
4. What if it made the unit bulkier, like 4" wide x 6" tall x 1" deep?
5. Do you have any marketting suggestions for me?

Ata.

Yes, especially if you could do 3D rendering based on the existing US
Topo 100K and 24K maps that Garmin sells.

20-50% for the maps if I could use an existing GPSr.

Oops! Maybe if the set came with battery discount coupons! :-)

No, no way.

Patent it--and then offer to sell to Garmin (unless you need a
Pentium-class chip to run it...).

Good luck--I'd love to have a moving, even simplified, 3D picture of
the terrain while driving or walking. Actually, I've often thought of
what it would take to get that kind of real-time rendering based on the
USGS topo maps in a regular GPSR (Garmin nuvi or 60CSx) both in terms
of the processor power and battery life.

What if it gave you the USGS topo rendered in 3D, was not battery hungry or
bulky, but the following
way: You see the top-down 2D view you have been used to sofar, pick a point and
a direction for the
camera, press the button, and 1 to 2 seconds later, you get a rendering with
waypoints and routes
superimposed.

So giving up the 100 frames per second might be the compromise to get smaller
size and longer
battery life.

How would you rate such a receiver against the standard one's today?

Thanks for the time you put into this.
Ata.

That's what I would like to have, not a 100 frames a second movie.

Nobody in his/her right mind would want it in a tiny GPSr anyway.

I want it in the next nuvi software upgrade! It's just SW, no? I'd
like to have it do 3D rendering of my 100K and 24K topo maps--is it
doable? I could live even with as little as some shadowing...

Great idea! Don't be discouraged by some Luddite-like comments below.

More or less. It would be nice to get more flash memory inside the unit which,
as you know, comes
at no extra weight or battery requirement, but litterally a few dollars more
cost to the
manufacturer. The only thing that it would accomplish is you could sandwitch
your route with more
off-route data which can benefit your detouring.

On PDA's like the Garmin iQue series, I would not even have to go through them.
I could just
compile my code and offer it directly. But it seems like a small market share
compared to all the
non PDA units.

Are you kidding. I built this algorithm with years of sweat and tears.

People like you are gold. Just a couple of replies back and forth and I already
know what the end
user needs. People like you deserve to have better kit. You don't just wine.
You provide the input
we need to improve.

The challenge is to get into the big manufacturers when you are a little guy.
Many of them don't
even know what you have to offer and have too much work load to return the
little guy's calls.
Something to remember when we grow, I guess. If only I could have more of their
customer's telling
them they want this feature. Oh well, there is more competition to go to. Hey
look, it's morning
in Amsterdam, TomTom is awake for the day. They made it from 0 to 25% of the
North American car
market in 1 year. Perhaps they will be interested.
