Abstract: A method for progressive drape update on avatar morph for a virtual fitting system comprises steps for providing an infrastructured avatar for a three-dimensional body, providing an OBJ avatar, providing a garment, draping the garment on the infrastructured avatar, providing a morphable avatar so as to wrap the infrastructured avatar, performing metamorphosis of the morphable avatar from the infrastructured avatar to the OBJ avatar so as to provide a plurality of transitioning shapes of the morphable avatar, applying physically-based simulation of draping the garment to the plurality of transitioning shapes of the morphable avatar, and displaying the garment draped on the OBJ avatar on the screen of the information processing device using a result of the physically-based simulation of draping with the last frame of the morphable avatar.

Abstract: A method for CIG-mode rendering in a virtual fitting system is provided. The method comprises step for: preparing a three-dimensional body, selecting a first garment for an outer and a second garment for an inner, assigning a plurality of inner-saver objects (ISOs), initializing all pixels of a stencil buffer for the screen; incrementing first pixels of the stencil buffer corresponding to interiors and RGB-drawing of the interiors, and the interiors comprise pixels of the outer or the inner, decrementing second pixels of the stencil buffer corresponding to exteriors and RGB-drawing of the exteriors, incrementing third pixels of the inner-saver objects and void-drawing the inner-saver objects; RGB-drawing forth pixels of the inner, where the stencil values are greater than zero.

Abstract: An automatic 3D garment construction is provided using steps for: providing a plurality of panels of a garment so as to be processed in an information processing device, wherein each of the plurality of panels comprises seam lines; positioning the plurality of panels at corresponding locations around a virtual body provided in the information processing device; finding matching seam lines for the plurality of panels and creating seams; and producing the garment in which the plurality of panels are positioned, seamed, and draped on the virtual body. The step for positioning may comprise a step for panel tagging, a step for seam line tagging, and a step for panel packing, in which related panels are grouped and packed, such that relative positions are fixed among the packed panels, and the packed panels move as a group.
