Rendering refers to process of creating images from a model of them
|
|
We will only look at case where image is of three dimensional world but much of our analysis will be generalizable
|
We intend to use such a 3D renderer to produce a 3D Image of New York State which can be navigated by children and teachers to provide a virtual field trip
-
This "New York State -- The Interactive Journey" is part of our Living Textbook project which will link remote host parallel machines to client PC's and Macintosh's in 6 schools linked to NPAC by high speed ATM network NYNET.
|
Current GIS systems tend only to support two dimensions properly with 3D either done crudely or in non real time mode. The Living Textbook project intends to use power of parallel machine to produce full 3D GIS.
-
Rendering and Map data will be on host parallel machine.
-
GIS Front End will be on Macintosh or PC in Schools

Much rendering research uses ray tracing and optimizes for the best possible Image quality
|
|
We will study texture mapped polygon method which is much faster and can give you ability to trade-off performance versus Image quality and guarantee real time constraint met.
