Title- An Introduction to MEL & Expressions in Maya.

Description- This workshop will serve as an introduction to MEL (MAYA EMBEDDED LANGUAGE) and its use through the command line, script editor and expression editor.  Participants will be introduced to scripting logic within the Maya platform and how this logic can be harnessed to create geometrical complexity.  Topics covered will include interface and navigation within Maya, fundamentals of variables, attributes, custom attributes and expressions. Emphasis will be placed on understanding how to harness these tools and effectively implement them through a series of architecturally relevant modeling exercises.

Location- HHN 308 (TBD)

Date + Time- 2009.11.02(6-9pm)

Requirements- Participants are required to bring a laptop with the following software installed:

Autodesk Maya 2009

Description: Grasshopper Scripting Level I

Topics will include:

1. Vector Basics
2. Grasshopper Scripting Interface
3. Coordinate System Mapping

Location:
Room HHS 416
Date + Time:

The following script allows you to array an object around a curve and designate a rotation.

You will need to do the following to execute the script

1. Select an object.
2. Set the “cplane” by designating 3 points (origin, X, Y)
2. Select a “curve” the array will occupy
3. Select the # in your array
4. Designate the degree of rotation.
