Snap Tool
Since FK/IK Rig is a very common but necessary setup, so is a tool that allows FK and IK controller
matching. Snap tool is an animation tool that match IK controller
to FK controller and vice versa.
Full Demo
## About The Project
I've come across two methods to achieve FK/IK snapping/matching,
both methods relies on assessing the joint info,
as controller is a layer on top of the joints and can be drastically
different across rig types.
- Constraint-based: used for easy setup
- **FK to IK**: use joint position in FK mode to point constraint IK controllers
- **IK to FK**: use joint rotation in IK mode to orient constraint FK controllers
- Vector math: used for generic setup
- **FK to IK**: set IK handle and IK root based on joint position in FK mode; calculate
mid-vector based on joint position in FK mode to set IK pole vector.
- **IK to FK**: set FK controllers to joint rotations in IK mode
## Getting Started
1. Unzip the [snapTool.zip](https://github.com/leixingyu/snapTool/releases/tag/v1.0.0) package under
`%USERPROFILE%/Documents/maya/[current maya version]/scripts/`
or a custom directory under `PYTHONPATH` env variable.
2. Launch through script editor:
```python
from snapTool import snapUI
snapUI.show()
```
## Usage
### Step 1: Assign Joints
the tools take a snapshot of the current active
result joint, and record its transform information.
### Step 2: Assign Controllers
assign either FK controllers or IK controllers
for matching by selecting it.
### Step 3: Snap!
click 'snap' will force the transform matching to the joint snapshot
