Technical Groups

Each technical groupAt least one person from each project group

Technical group – learn one major facet of software

Technical groups

• Modeling: polygons, NURBS, subdivision surfaces

• Animation: Forward kinematics, IK, particle systems

• Rendering: playblast, rendering qualities, recording frames, video editing, post-processing

Immediate Tasks

Form into groups

Start thinking of animation project

Consider software tasks

Computer AnimationRick Parent

By End of WeekForm groups

4-5 CSE students

At the end of Wednesday’s class, anyone not in a group will be put into one

Have an idea of technical group assignment
