Motion Capture  21
14. Return to frame –13. You can now begin adding handles and constraints to the rest of the
joints. For quick reference, Figure1.26 shows the point and orient constraint options.
15. Add an SC handle from spine1_JNT to spine2_jnt.
16. Shi+select thorax from the motion-capture skeleton and ikHandle2. Add a point
constraint.
17. Shi+select upperback from the motion-capture skeleton and ikHandle2. Add an
orient constraint.
18. To nish the spine, add an SC handle from spine2_JNT and collar_JNT.
19. Shi+select lowerneck from the motion-capture skeleton and ikHandle3. Add a point
constraint.
20. Shi+select thorax from the motion-capture skeleton and ikHandle3. Add an orient
constraint.
21. For the le leg, follow the same procedure all the way down the skeletal chain. Here
is a list of the constraint mappings:
SC IK Handle Point Constraint Orient Constraint
ikHandle 4 ltibia lfemur
ikHandle 5 lfoot ltibia
ikHandle 6 ltoes lfoot
ikHandle 7 ltoes_end ltoes
