Maya Techniques Bi-Directional Constraining Part II
Description
This two-part series is aimed at Technical Directors and those with some experience with MEL scripting and API programming. Bi-Directional Constraining Part II: Breaking the Cyclic Dependencies will present a method to free up the animator from the uni-directionality of Maya relationships. This class will introduce a new constraint that can change source and destination objects interactively as well as during animation playback. You will benefit from practical examples on how to use this new paradigm for character rigging, character to character interaction and character to prop interaction. You’ll also explore how this constraint was developed through an in-depth analysis of the problems associated with traditional methods of constraining. To aid your understanding, this two-part series will provide you with a foundation of knowledge on Maya's Dependency Graph evaluations, with an “under the hood” look at what a transform is and how they are built in hierarchies, coordinate space basics, and finally the structure of the constraint node.
You Will Learn
* Classic Animation Workflow & Limitations Of Character Interactions
o Traditional Constraining Paradigms With Props
o Traditional Character Rigging Constraints
o Examples of Multi-Way Rigging Approaches
* Maya Node Evaluation Basics
o Dependency Graph Evaluation Rules
o DAG Coordinate Space Structures
* The Unidirectional Nature Of Constraints And A Solution
o Going Around DG Evaluation Problem With A Switch
o Going Around The DAG Structure Using A Reference Coordinate System
* Coordinate Space Basics
o Transformations - Under The Hood
o Understanding Transformation Concatenation
o Manipulating Coordinate Spaces With Vectors & Matrices
o Examples of Manipulating Nodes In Maya With Vectors & Matrices
