This is the second part of the tutorial dedicated to one of the most used Mathematical tools in Game Development: linear interpolation! In this part, we will explore how to extend the concept of linear interpolation to non-linear mappings. The final part will explore how to use them to correct colour curves.

• Part 1: Linear Interpolation
• Part 2: Piecewise Interpolation
• Part 3: Color Curve Correction
