1.获得一个obj模型文件(可以使用3dmax等建模软件制作，亦可直接百度下载) 2. 1)下载ActivePerl(百度下载) 2)下载obj2opengl(可以将.obj文件转化成.h) 3.将obj2opengl.pl和你需要转换的obj放到C:\Perl\bin目录中 (这里我们以banana.obj为例) 4.运行命令提示符，定位到C:\Perl\bin目录下，输入命令：perl obj2opengl.pl banana.obj
这时候你会发现，bin文件夹中自动生成了banana.h文件。 5.修改代码 这部分有点繁，等哪天有空了再写教程，先放上代码… 1)仿照Teapot.java，新建一个Banana.java 主要任务是要替换模型数据，由于数据量大，这里使用了文件操作，我将verts, norms, texcoords三个模型数据放在文件中分别导入
同时要注意的是，TeaPot的实现有4个参数，而使用obj2opengl导出的.h数据中只有3个参数，缺少indices数据，不过不影响模型的显示，Sample中的Building也是只有3个参数，但具体原理我就不太懂了，跟opengl的知识有关，还望大神指教
