Hermite Curve Interpolation - English
URL: http://www.cubic.org/~submissive/sourcerer/hermite.htm

Hermite curves are very easy to calculate but also very powerful. They are used to smoothly interpolate between key-points (like object movement in keyframe animation or camera control). Understanding the mathematical background of hermite curves will help you to understand the entire family of splines.

Stair Interpolation (SI) - English

Everyone involved with digital imaging has heard about Genuine Fractals. This utility claimed to do a better job interpolating digital images than Photoshop's bicubic engine. Now I would like to introduce a new utility. It's called SI.
