有哪些好的 3D 插值库? [英] What are some good libraries for 3D interpolation?

问题描述

有哪些用于(快速)3D 插值的好库?最好在 C++ 中，但我也对其他人感兴趣.(尤其是 Matlab)

What are some good libraries for doing (fast) 3D interpolation? Preferably in C++, but I'm intrested in others, too. (Especially Matlab)

推荐答案

在 Matlab 中，3D 插值由 INTERP3.为了获得一些速度增益，请在您的方法参数前加上星号(例如 '*cubic' 而不是 'cubic').为了获得更多的速度增益，您可以将插值代码从函数中取出并跳过所有错误检查.

In Matlab, 3D interpolation is performed by INTERP3. For some speed gain, pass your method argument preceded by a star (e.g. '*cubic' instead of 'cubic'). For some more speed gain, you can just lift the interpolation code out of the function and skip all the error checking.

一个好的 C++ 实现可能会更快，例如介绍的那个 此处在 Matlab 文件交换中(从未测试过).

A good C++ implementation is likely to be faster, such as the one presented here on the Matlab File exchange (never tested it).
