Realtime 3D animation of Human spine using three.js

You will be provided with a very high quality model of the human spine in COLLADA format so you can use it with [login to view URL] which is built on top of D3.js for 3D rendering and animation. Your task would be to use [login to view URL] to render it and animate it such that the movements of the spine is achieved in the attached video. As a final test, I will also provide you with orientation data (x, y, z coordinates) in CSV file, so you can test your animation program's accuracy - you only need the orien_x, orien_y and orien_z columns in the CSV file. In addition, the resulting animation program should be able to accept inputs (orien_x1, orien_y1, orient_z1 for Cervical region Cl -C7, orien_x2, orien_y2, orient_z2 for Thoracic region Tl-T12 and orien_x3, orien_y3, orient_z3 for Lumbar region Ll-L5.) and make transformation in all 3 regions of the spine independently or in combination with other regions of the spine. Please provide me with an estimate of how many hours it will take to get this done.
