Blender是一个全面开源免费的三维建模渲染软件.针对教育,学习,专业人士等各种人员都可以使用他.内建Python脚本支持,非常棒.
支持:windows/linux/unix/mac os/FreeBSD等
Blender是基于SDL以及Python以及其它一些相关的开源技术所构建的,在GPL协议下你可免费使用,分发,当然也可以修改其源码.

软件界面友好,用起来还是挺顺手的.建模功能丰富而而迅速.强大的动画制作系统,以及骨骼制作.渲染,建模,粒子也不错.而且编辑功能也很丰富,再加上导入导出格式很多,你可以与.X文件,或是3DS MAX,MAYA等一流软件配合使用,也是个不错的主题.
下面是一些英文介绍,有兴趣的朋友可以下载一份试试.
Blender therefore is fully free to use and distribute within any educational, professional or commercial environment. Artwork created with Blender - including python scripts - is the sole property of the creator.
