NAME
world_to_obj - transform from world to object coord frame
PROTOTYPE
unitptr world_to_obj( int n, unitptr host)
ARGUMENTS
- int n
- number of points to be transformed
- unitptr host
- host unit for newly created instance
RETURN VALUE:
- unitptr u:
- pointer to newly created unit
INTERFACE OF CREATED UNIT:
- in_0[3]:
- world coordinates of first point
- ...
-
- in_n-1[3]:
- world coordinates of last point
- out_0[3]:
- object coordinates of first point
- ...
-
- out_n-1[3]:
- object coordinates of last point
If n==0::
- out_0[16]:
- world coordinate frame (as a homogeneous
4x4 matrix) relative to object coordinates.
Columns 0-2 are unit vectors along world x,y and
z-axis in object coordinates. Column 3 is origin
of world coord frame in object coordinates.
