Abstract

貝茲曲線內插法分段式 Bezier curveInterpolationSubdividing.
Outline font is one of method to represent font that consists of a series of straight line segmentsor curves. Usually they are designed as Bezier curves. In this thesis, we are goingto interpolate two different outline fonts. We propose a pretty simple algorithm to solvethis problem. We input two different outline fonts. Then we perform subdividing or cuttingcurve before interpolation. We cannot directly interpolate them because the composition ofeach font character is quite different, such as the total number of curves, position and sizeare totally different. We use subdividing curve method for cutting curve. The final outputof total number curves of first and second font should then be same. Then we perform interpolationfrom the first to second font at any time point 0 · t · 1. For each t value, wecan create a new curve as the final output for new outline font after interpolation. We alsoprovide some experimentation results.
