here is the meaning of the rotation matrix:
set_view (\
#rotation matrix, describes the orientation of
#the object relative to coordinate system:
-0.423272938, 0.519671082, -0.742144108,\
0.565680504, -0.488278866, -0.664524078,\
-0.707710445, -0.701090038, -0.087292627,\
#Position of the object relative to world coordinates:
0.000000000, 0.000000000, -108.510879517,\
#Coordinates of the object rotation center:
21.806344986, 33.097042084, 26.156803131,\
#Near and far clipping planes, and the orthoscopic flag:
81.724128723, 141.037658691, 0.000000000 )

Here is a simple script that saves the molecule
with coordinates from the current orientation.
# Adds the command save_transformed
# Usage: save_transformed object, file
def save_transformed(object,file):
m = cmd.get_view(0)
ttt = [m[0], m[1], m[2], 0.0,
m[3], m[4], m[5], 0.0,
m[6], m[7], m[8], 0.0,
0.0, 0.0, 0.0, 1.0]
cmd.transform_object(object,ttt)
cmd.save(file,object)
cmd.extend('save_transformed',save_transformed)
