Assignment 1 - Basic Character Animation

In this assignment, you will become familiar with fundamental data structures and the animation creation workflow. Your task is to craft an animation clip using the provided infrastructure. Also, you need to understand the mathematical concepts behind Forward Kinematics (FK) and Inverse Kinematics (IK), and then to interpret the motion capture files and interact with them.

Details: [subfolder]

Tutorial Slides

1. Basic Linear Algebra in Graphics [slide]
2. Forward and Inverse Kinematics [slide]

Assessments

• A rendered video with character animation (Task 1, 40%)
• Core code implementation of Forward Kinematics (Task 2, 25%)
• Core code implementation of Inverse Kinematics - CCD IK (Task 3, 25%)
• Report (10%)

Useful tutorials of Blender

• Basic operations of Blender
• Character rigging
• Keyframing animation

Assignment 2 - Animation Processing and Scripting

This assignment will provide a practical introduction to working with animation data through various algorithms such as interpolation and concatenation. Additionally, you will learn to consider various variables from motion data to enhance the performance of the motion matching method.
