model & animate a 3d person moving in C++

Please study this project description carefully and ensure that you are able to do this before applying. This is not an easy task to complete. I need 2 x 3d models of people, an adult in low detail and an adult in high detail. These need to be of a regular person in normal life, not a game character with guns, etc. I would like these models built in .3ds or .obj format. I would like c++ code that will load these models into a set of 3d meshes, and animate the meshes in four ways: - walking - running - sitting down - falling down I need the code built into a C++ class (or classes) without boost or any other complex software libraries. This code needs to be as simple as possible, and able to build on linux (gcc) and windows (mingw). Extracting the code out of a gaming or animation tool/ engine will probably not be a good solution. The interface of the class should allow me to: - get pointer to the mesh data structure - set movement type (walk/ run/ sit/ fall) - set movement speed - set time the mesh should have the following data structure: - a vector of points, each point being a struct with 3 elements being x,y,z coordinates, and 3 elements being x,y,z direction of the normal - a vector of triangles each triangle being a struct containing 3 indices into the points vector. They will point to the three vertices of the triangle. The rigging & animiation of the 3d models should match industry standards if possible so that other 3d models of people can be loaded and used if needed. Please also build a basic program that will display & animate the result in a Qt or opengl window. If you are able to do only part of this project (either the modelling or animation), or you believe there is a better solution, please let me know. In your proposal, please describe how you will complete this. Also, please begin your proposal with the words 'happy days' so demonstrate that you read the whole project description. thanks
