This module has mainly the three purposes denoted above. The input for this part of the pipeline is coming from the facefeatures part and its output is used by the webgl viewer to render 3D model. After this processing step the 3D model is deformed according to the inputs, its normals have been recomputed, to reflect the actual and surface normals and the minimum and maximum dimensions of the model's bounding box is passed on to perform the texture mapping correctly in the next step.
