Abstract
Shift of each stitch in a fabric is repeated and converged to eliminate the difference between distances to surrounding stitches and a default value, the deviation of an angle formed by a line connecting the right/left stitches and a line connecting the upper/lower stitches from 90°, the difference of an angle formed by the right/left stitches formed
Claims5
A loop simulation apparatus for creating a knitted fabric image corresponding to design data of a knitted fabric such that a loop of each individual stitch is represented, characterized by:
- means for determining a distance deviation between a distance from each individual stitch on said knitted fabric image to an adjacent stitch and a standard value thereof as a tension;
- means for determining a deviation between an intersection angle between a line linking each individual stitch on said knitted fabric image to an adjacent stitch in a course direction and a line linking each individual stitch on said knitted fabric image to an adjacent stitch in a wale direction and a standard value thereof as a distortion angle;
- means for determining a deviation between an angle between two stitches adjacent to each individual stitch on said knitted fabric image in said wale direction, with respect to an axis expressing an orientation of each individual stitch on said knitted fabric image to an adjacent stitch in said course direction, and a standard value thereof as a bending angle about a course axis;
- means for determining a deviation between an angle between two stitches adjacent to each individual stitch on said knitted fabric image in said course direction, with respect to an axis expressing an orientation of each individual stitch on said knitted fabric image to an adjacent stitch in said wale direction, and a standard value thereof as a bending angle about a wale axis;
- and
- shifting means for shifting a position of each individual stitch on said knitted fabric image to reduce said tension, said distortion angle, said bending angle about said course axis, and said bending angle about said wale axis.
