Mastering Maya: Understanding Dependency Graph and Attribute Connections

Explore Maya's internal representation nodes and attributes, learn about Dependency Graph, different types of nodes like shape, transform, and expression, and their connections in the Hypergraph. Dive into Attribute Editor, creating expression nodes, and using MEL/Python for scripting and expressions. Enhance your skills in creating particle expressions and manipulating objects through MEL scripting.

  1. MEL Interface with Maya

  2. Maya's internal representation     nodes     with attributes     connected to each other

  3. DependencyGraph Types of nodes shape transform group expression shading etc. WIndows->Hypergraph:Connections

  4. Attributes types     integers     floating point     enumerated     vectors     matrices     arrays connections: links between attributes

  5. AttributeEditor 1st of upper right icons displays keyable attributes Windows->General Editors ->Attribute Editor

  6. Connections upstream v. downstrearm

  7. directed acyclic graph DAG  transform hierarchy Scenehierarchy subset of DG WIndows->Hypergraph:Hierarchy

  8. Outliner Windows->Outliner

  9. MEL/Python command line script editor

  10. Script Editor

  11. Expression Nodes similar syntax to MEL, but not same MEL: setAttr(pSphere.translateX) = 10; Expr: pSphere.translateX = 10; write MEL script to define expression nodes particle expressions object attribute expressions 1. define variables 2. compute value 3. assign value to attribute

  12. Expression Editor Window->Animation Editors->Expression Editors
