VC编写的基于对话框的OpenGL程序，可动态读raw格式的纹理-VC prepared by the OpenGL-based dialog procedures can dynamically read the raw texture format

利用OpenGL根据.raw作为高度图文件绘制地形,按键f为GL_FILL模式,按键l为GL_LINE模式,m为纹理贴图的地形,c为自己设置颜色的地形,h和t切换不同的地形.-The use of OpenGL in accordance with. Raw height map as a document mapping the topography, key f for GL_FILL mode l for GL_LINE mode button, m for the texture map
