----------------------------Original message---------------------------- >> I've been marketing a program called Landscape Explorer as shareware ... Yes, I'm familiar with Landscape Explorer. Excellent work! I'm obsessed with the idea of recreating landscapes that no longer exist, and then traveling through them. I've written several different "Map Visualization" using tools Visual Basic to explore rendered landscapes built with Vistapro. It seems to me that - eventually - cheap PCs will be a standard tool used in cartography through the use of programs like Landscape Explorer and Vistapro. I believe television news and other visual media will regularly use these types of tools to give the public a more realistic view of geographic areas. Today a person needs to establish pre-defined paths of travel through a landscape and generate (render) individual frames of a fly-through. Eventually Virtual Reality applications will be written for your average PC that enable us to travel through highly detailed landscapes in real time. Hey, maybe in release 2.0 of Visual Explorer! -Vin +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ Check out my home page for sample 3d fly-through of the Bull Run area in the 1860s (US Civil War): Web Home Page: http://home.aol.com/menotomy +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
