用Perl在3D立方体中的点或球体

概述假设我有@points [$number] [$x] [$y] [$z] [$color],我只是出于调试目的,希望它们在3D立方体中可视化以更好地观察我拥有的内容.通常我将它们导出到* .txt并使用R 3D绘图,但也许在Perl中有简单的方法可以做到这一点？ 拥有半径的球体会更好. 我的回答：使用OpenGL perl绑定 我还没有完全回答你的问题,但我确信你可以采用这个代码 我以前没有做过O 假设我有@points [$number] [$x] [$y] [$z] [$color],我只是出于调试目的,希望它们在3D立方体中可视化以更好地观察我拥有的内容.通常我将它们导出到* .txt并使用R 3D绘图,但也许在Perl中有简单的方法可以做到这一点？

我还没有完全回答你的问题,但我确信你可以采用这个代码

我以前没有做过OpenGL,但这是一个有趣的小夜晚项目
