Notes on .JAW files:
|
|
This is a file format created by Jawed Karim for Jaw3D
|
|
(http://jaw3d.home.ml.org).
|
|
-- updated 11/6/00 - www.jawed.com
|
|
It is very simple, and lets one easily create ones own models using only
|
|
a text editor. The format is pretty simple:
|
|
The first line must be "Light: (x,y,z)" where x,y, and z are the x y and
|
|
z components of the lightsource vector (I think ;)
|
|
A series of lines, numbered 0 to n, in the format of
|
|
"i: x y z", where i is the vertex number (which should be listed in
|
|
order, and x y and z are the coordinates of that vertex.
|
|
A series of lines, having the format "tri a, b, c" where a b and c are
|
|
the vertices that the face uses. It is unclear at this time which
|
|
way the vertices are listed (ccw or cw), so just make em consistent
|
|
and you can always use plFlipObjectNormals() on the loaded object.
|
|
That is it! (I told ya it was simple).
