Three-dimensional reconstruction of the idea is very simple, with OpenGL texture mapping function, the plane image of the triangle one by one to the calculated three-dimensional coordinates up on it. In order to facilitate the observation of 3D effects, I also designed the interactive function: the arrow keys can be rotated up and down around the reconstructed model, with the mouse wheel can zoom in or out. Use gluLookAt function to achieve the function of point rotation. The three-dimensional reconstructed code is implemented in glFuncs.cpp.
