There are two methods of doing this, either to an entire hierarchy of items or to specific sections of a hierarchy. This can be done to a hierarchy of items, or to a full Skeleton, and can be applied either before or after the binding process. The first step in using IK in MODO is to assign it to the items that you want it to work with, this needs to be done in ' Setup' mode as this will define the rest positions for each joint. The setup of the chains is done easily by simply selecting the target elements and applying the commands found in the toolbox of the 'Setup' and 'Animate' interface tabs under the 'Inverse Kinematics' subtab. While it is commonly used for characters, it can be applied to any hierarchy chain of locator based items. MODO's Full Body IK is an automatic IK system that will work in a wide variety of rigging situations. MODO has implemented an IK system that is fairly automatic and extremely robust. IK works in reverse and is far more intuitive, simply grab the hand and bring to the object and the wrist, the elbow and shoulder joints adjust automatically, maintaining their proper orientation toward the goal, in this case, the hand. If lucky, it would only take a few attempts to get the hand properly positioned to the object. With FK, you would first position the shoulder joint, then the elbow and finally the wrist. For example say you wanted a characters arm to reach for an object on a table.
With forward kinematics, one starts animating by positioning the root element and then adjusting all the element down the chain. Add to that topological symmetry, layered multi-resolution sculpting, new Slice and Cap options, Quad Fill, Linear and Radial Align, Multi-slice and more, and polygon modeling is faster, easier and more efficient than ever.There are two methods for animating hierarchies of elements (such as a character) - forward kinematics (FK) and inverse kinematics (IK). Now a fully integrated feature included in MODO 901, MeshFusion takes away the challenge of complex and frustrating Boolean operations, making it easier to consistently produce high-quality models. When it comes to modeling and sculpting, MODO 901?s renowned toolset just got better.
