C language implementation of Multithreaded Animation program Sample _c language

The program is a simple 3d animation program written using OpenGL graphics library and Fmod Audio library. This program works well under vs. if the associated DLL file is missing, please confirm that the FMOD and OpenGL libraries have been prepared.
