MEL and Expression : Object and Attributes

Object : existed objects in a scene such as nurbs shpere, polygon plane, ambient light, Phong shader, etc.


These objects has original attributes. There are different types of attribute like attribute related to translation, rotation, scale ( translateX, rotateY, scaleZ), relate to shape (radius, spans), related to material (colorT, transparencyG, specularColorB) and many others.
