[其他] 命令行 三维模型渲染绘制器

v v.exe
摘要：命令行下的 ASE、PLY 三维模型文件绘制工具。不足50KB, cpu使用率不到百分之一,黑窗口下高质量渲染三维模型

版本：1.8
用法：（控制台窗口输入命令）
vv [ASE文件路径]

请及时下载,失效后不在补更
  1. 控制：

  2. A、D 按键控制图像 左右旋转

  3. W、S 按键控制图像 上下旋转

  4. Q、E 按键控制图像 Z轴倾斜

  5. Z、X 按键控制图像 缩放

  6. 

  7. O、P 按键控制灯光强弱

  8. 

  9. Y 按键 开启、关闭 二级旋转开关

  10. U 按键 渲染模式切换： 1.面渲染 2.点渲染 3.线渲染 4.白模渲染

  11. I 按键 开启、关闭 材质加强渲染开关

  12. 

  13. R 按键重置图像，复位键

  14. 空格键 控制图像 暂停、旋转

  15. 回车键 控制程序 关闭

  16. 

  17. 2、8 按键控制图像 上下平移

  18. 4、6 按键控制图像 左右平移

  19. 7、9 按键控制图像 里外平移

  20. 

  21. 补充：

  22. 附带的FreeImage.dll图像插件如果删除，vv.exe将会启用内置gdiplus显示模型。

  23. 脱离FreeImage图像插件后，vv将无法加载dds、tga等纹理贴图，但此时可实现在

  24. PE下独立运行。
