使用d3d9中的粒子系统和普通的面片做成的喷发器，可以模拟炮弹落下时的情景。需要有PLANE面片类才能运行。-D3d9 use of particles in the system and the ordinary surfaces made of eruption, you can simulate the scenario when the shells fell. PLANE patches need to have categories in order to run.

Ras2vec 源码 Ras2vec是一个用于将光珊图像转换为矢量图的工具，适合于将光珊格式（支持BMP、TIF）的工程图纸、地图、构件图转换为可无级缩放的矢量格式（支持EMF、DXF等格式），功能十分强大。同时它也是一个完全符合GPL协议的自由软件，提供了完整的源代码，推荐使用！作者：Davide Libenzi，工具：通用C 。-Ras2vec is a source for optical Alexandra images to vector conversion tool, suitable for optical Alexandra formats (BMP, TIF), engineering drawings, maps, plans components can be converted to no-scalable vector format (EMF support, DXF format), the function is very powerful. It is also a fully consistent with the GPL free software, provides a complete source code, recommended! Author : Davide Libenzi, tools : Definitive C.
