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

控制：

A、D 按键控制图像左右旋转

W、S 按键控制图像上下旋转

Q、E 按键控制图像 Z轴倾斜

Z、X 按键控制图像缩放

O、P 按键控制灯光强弱

Y 按键开启、关闭二级旋转开关

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

I 按键开启、关闭材质加强渲染开关

R 按键重置图像，复位键

空格键控制图像暂停、旋转

回车键控制程序关闭

2、8 按键控制图像上下平移

4、6 按键控制图像左右平移

7、9 按键控制图像里外平移

补充：

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。

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

PE下独立运行。
