卡特莫尔-ROM样条为Android [英] catmull-rom splines for Android

问题描述

我试图找到一种方式来实现，通过N点平滑画线的目的，在Android平台上的Catmull-ROM样条。理想情况下，我将能够通过路径及其cubicTo方法，在这个线程提到适应立方米贝济耶：<一href="http://stackoverflow.com/questions/4712003/how-do-i-draw-a-curve-through-tree-points-in-android">How我在Android中画出一条曲线通过植树点？

I'm trying to find a way to implement catmull-rom splines on the android platform for the purpose of smoothly drawing a line through n points. Ideally I would be able to adapt cubic beziers via the Path and its cubicTo method as alluded to in this thread: How do I draw a curve through tree points in Android?

不幸的是，我不是能够遵照执行有，所以我希望有人在那里已经做到了这一点，并可以共享的样本code的几行。

Unfortunately, I wasnt able to follow the implementation there so I'm hoping somebody out there has already done this and can share a few lines of sample code.

谢谢！

推荐答案

为Android这个游戏的开发库似乎有<一个href="http://www.google.com/$c$csearch/p?hl=en#c5txscj0tnc/trunk/gdx/src/com/badlogic/gdx/math/CatmullRomSpline.java"相对=nofollow>卡特莫尔-ROM样条 <一href="http://www.google.com/$c$csearch/p?hl=en#c5txscj0tnc/trunk/tests/gdx-tests/src/com/badlogic/gdx/tests/SplineTest.java"相对=nofollow>实施：的http：// code。 google.com/p/libgdx/ 。

This game development library for Android seems to have Catmull-Rom splines implemented: http://code.google.com/p/libgdx/.

PS，你标记贝塞尔，这是不正确 - 这是一个使用控制点具有外部影响:)

p.s., you tagged Bezier, that's incorrect -- that's the type of curve that uses control points outside the curve which have external influences :)
