[Radiance-general] Major Axis definition

[Marcus Jacobs]

Dear Group

I am looking into using tmesh.cal in order to map patterns onto polygons 
with a Radiance converter that I have written. In tmesh.cal, it defines the 
first argument as :

A1 = Major axis (0==X, 1==Y, 2==Z)


I have no clue to exactly what this is. Could anyone *coughGreg* provide an 
explaination of this.


Thanks


Marcus
