I2LW version 1.0
Copyright (C) 1994 Peter Verswyvelen

--------------
Introduction
--------------
I2LW is a simple 3D object converter. It takes as input an Imagine
group of TDDD objects and outputs a LightWave object.
Each TDDD object in the group is converted to a LW surface of
polygons. The surface gets the same name as the TDDD object, with
an optional prefix added.
During the conversion, I2LW performs 2 important optimizations :
(1) All triangles (called 'faces') are re-oriented so that their
'normal vectors' will point 'outside' the object.
ADVANTAGE: Each polygon in Lightwave has only one visible side.
When the TDDD faces, which will merge into LW polygons, are not
re-oriented you will have 'gaps' in your LW rendering. You can
solve this by enabling the 'Double Sided' LW feature, but this slows
down the rendering process. So nomore gaps and more speed !
(2) Each pair of coplanar faces is merged into a quadrangle, a
polygon with 4 points (and 4 edges :-)
ADVANTAGE: 'nicer' objects, less memory consumption and faster
rendering.
NOTE: THE DEMO VERSION OF I2LW HAS A LIMIT OF 500 POINTS AND CAN
CONVERT A SINGLE TDDD OBJECT ONLY.

Requirements
---------------
MS-DOS:
80386 or higher
math coprocessor
AmigaDOS:
AmigaDOS 2.0 or higher
68020 or better
math coprocessor
--------
Usage
--------
I2LW is run from the command line prompt only. The first argument
is the (input) filename of the Imagine TDDD object, the second
argument the (output) filename of the LightWave object, and the
third (optional) argument is a string which will be the prefix of
each surface name.
MS-DOS Example:
I2LW C:\IMAGINE\COW.OBJ A:\CONVERT.LW COW_
will read the TDDD group 'COW.OBJ', display a lot of info on the
screen, and write a LightWave object 'CONVERT.LW'. The first object
in 'COW.OBJ', which we assume has the name 'BODY', will be converted
into a Lightwave surface named 'COW_BODY'. This conversion
continues until all objects in the group are done.
