问题 I am interested in creating a 3D visualization of network packets. A few years ago these things sold for tens of thousands of dollars, but now I think that I can hack one together in a few hours using an open source 3D kit. I've looked around and have found two kids that look good --- one is Panda3D and the other is CrystalSpace. My requirements are: Fast to learn Able to run from python or C++ Able to work with 50,000 polygons. (I want to represent each packet as a little brick in 3D space.)

　　很多开发者认为Python是比Java更高效的语言，Python是一种解释性语言，伴随着优雅的语法，它是脚本编写和快速应用程序开发在许多领域的绝佳选择。 　　Python是一种动态类型的编程语言，无需声明变量。而Java是一种统计类型的编程语言，其中必须明确声明变量。 　　即使未列出某些Java“类外壳”，Python代码也太小，这可能是python可能更具生产力的原因之一。 　　Java是一种统计类型的通用编程语言，它是一种面向对象的并发语言。 　　Java的含义是WORA(在任何地方运行一次即可编写)，它旨在在Java虚拟机(JVM)的帮助下在任何平台上运行，并且具有尽可能少的依赖性。 　　Python是一种动态类型的通用编程语言，其背后的主要动机是建立一种高级语言来弥合C和Shell之间的鸿沟。 　　该语法还受到诸如Algolol，Pascal和ABC之类的语言的启发，它的含义是易读且简洁。 　　Java 　　代码扩展代码行，而不是Python。 　　动态在Java编程中，您必须声明数据类型。 　　语法在程序结束时，如果你错过了分号，则会出现错误。在Java编程中，必须在特定块之后或之前使用花括号，如果不使用花括号，那么没有花括号，代码将无法工作。 　　可移植性Java随处可见,由于这个Java虚拟机(JVM)几乎随处可用。 　　速度关于速度，Java更快。在项目速度方面

问题 I already checked ( in stack exchange and other sites) and googled my problem but all solution seems useless. Here's the problem : My computer had win xp and had python2.7 and panda3d (version 1.8.1) installed (python in D: and panda3d in C: ). The module was working perfectly. Unfortunately I had to format my C drive. I upgraded to win 7 instead of installing xp again after formatting. Now I had python 2.7 in my D: drive (Which had not been formatted) working perfectly well and only had to

问题 I'm trying to learn panda 3d, but I'm getting this error importerror no module named direct.showbase.showbase I'm using the latest versions of panda 3d 1.7.2, python 2.7 on windows xp, how to fix the error? 回答1: http://www.panda3d.org/forums/viewtopic.php?t=10363 Panda 3D on Windows comes with a special version of python that is preconfigured to work correctly with Panda, that python is run with ppython . Otherwise you need to add the Panda libraries to your Python path from the Panda install
