MEL Interface with Maya Mayas internal representation nodes

MEL Interface with Maya

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

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

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

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

Connections upstream v. downstrearm

Scene hierarchy subset of DG directed acyclic graph DAG transform hierarchy WIndows->Hypergraph: Hierarchy

Outliner Windows->Outliner

MEL/Python command line script editor

Script Editor

Expression Nodes similar syntax to MEL, but not same MEL: set. Attr(p. Sphere. translate. X) = 10; Expr: p. Sphere. translate. X = 10; write MEL script to define expression nodes particle expressions object attribute expressions 1. define variables 2. compute value 3. assign value to attribute
