Interpolation calculates a value between two other values. For example, the number 5 is halfway between 0 and 10. Different types of interpolation use different rates of change between values. Linear interpolation, abbreviated as lerp, uses a constant rate of change. The lerp() function linearly interpolates between two numbers.
