3D garment designing has a variety techniques at our disposal of 3D form creation – Loft, Network, T-Splines The first one – Loft technique is good for re-forming the mesh-scan of the person into 3D digital body model Re-topology (i.e. high quality transformation) of irregular pitted asymmetrical mesh surface into the smooth and nice 3D body form is done quickly with the help of Loft technique Loft to be devised to correct volume forms, asymmetries and surface irregularities It is extremely difficult to make a mistake even having lack of experience as the clear and easy algorithm of this technique a high quality result within half an hour of work It is not convenient to design garment with the help of Loft – it appears to be a one-off surface, it is extremely complicated and boresome to reshape it with another seam allowances or change the form completely It is much more convenient to create 3D digital body model of the client by Loft technique then make garment designing with the help of T-Splines T-Spline modelling allows to quickly get the various 3D forms of the garment which could be much far from anatomic form of 3D digital body model T-Splines allow various surface topology options, meaning that relative location of apexes and edges in relation to each other can vary endlessly Nothing can limit your creativeness However, it will not be easy to cut out the created form along surface lines or darts – T-Spline form being a number of polysurfaces and you might have you dress or coat pattern consisting of 5 pieces, for example So, every time you cross the edge of polysurface, you would have to start again to draw the line, smoothness of lines being violated andre-drafting being more complicated So, you would have to put together slops from pieces, no integral surface is possible One more technique to mention is Network designing This method allows controlled re-drafting of garments, by changing fit, allowances and form within reasonable limits If you are going to draft patterns by Network, it makes sense to create 3D digital model from scan of the client by Network as well In this case one can easily and quickly move from digital model of the client to garment design, as in fact 3D body model being tight form of the scan What are the advantages of Network drafting in comparing to T-Splines drawing 3D garment drafted by Network being the integral surface where one can easily put the lines Moreover this process could be set as automatic process so the lines would be put on a 3D form on their own under your explicit control You will be working on a planar map monitoring lines location on a 3 dimensional form We would like to emphasize that there is no ideal technique that fits to everyone, each technique has it’s own pro and cons Thus each 3D professional has its own best practices that most fit to their needs and tasks Any questions left?
