Converting Between Co-ordinate Systems


=Td SCREEN X(x,y,z)........Returns the AMOS X co-ordinate of world
co-ordinate x,y,z

=Td SCREEN Y(x,y,z)........Returns the AMOS Y co-ordinate of world
co-ordinate x,y,z

=Td WORLD X(n,x,y,z).......Takes a point (x,y,z) expressed in local
co-ordinates relative to object n and returns the world X co-ordinate

=Td WORLD Z(n,x,y,z).......Takes a point (x,y,z) expressed in local
co-ordinates relative toobject n and returns the world Z co-ordinates

Td VIEW X(n,x,y,z).........Takes a point in world co-ordinates and converts
it to the local X co-ordinate relative to object n

Td VIEW Y(n,x,y,z).........Takes a point in world co-ordinates and converts
it to the local Y co-ordinates relative to object n

Td VIEW Z(n,x,y,z).........Takes a point in world co-ordinates and converts
it to the local Z co-ordinates relative to object n
