Abstract
A realistic image of woven cloth surface is provided by a system which receives a user input of a yarn cross section design to produce a side view image of a resultant spun or unspun yarn and which utilizes either basic weave patterns or user-designed patterns to produce a woven cloth images. Shading is applied to the cross-sectional image of each fiber selected in a yarn to provide a realistic image of the resultant spun-yarn. Shading is also applied to portions of each warp and fill thread in the vicinity of their intersecting each other to provide a realistic woven fabric surface image.
Claims35
In a computer-assisted design system having data storage memory, a display device for displaying an image corresponding to a data set in said memory and a logic control system for manipulating data, a method for generating an image or a textile article comprising:
- establishing with said control system a two-dimensional data set in said memory representative of an image of a lateral cross section of a bundle of fibers;
- transforming said data set with said control system in a manner that will project said image of a lateral cross section along an axis perpendicular to said image of said cross section in order to generate a second two-dimensional data set in said memory representative of a first image of a longitudinal side of a yarn including said bundle of fibers;
- scaling said second two-dimensional data set with said control system to create a third data set representative of a second image of a longitudinal side of a yarn having a diameter smaller than said first image;
- and
- displaying with said control system said first and second images of longitudinal sides of said yarns on said display device.
In a computer-assisted design system having a data storage memory, a display device for displaying an image corresponding to a data set in said memory and a logic control system for manipulating data, a method for generating an image of a textile article comprising:
- establishing with said control system a first two-dimensional data set in said memory representative of a lateral cross-sectional image of a bundle of fibers, such that each of said fibers has a color hue value and a plurality of portions, each of said portions having a shading value, the shading value of each of said portions being dependent on the radial spacing of that portion from the center of the associated fiber;
- transforming said first two-dimensional data set with said control system in a manner that will project said cross-sectional image along an axis perpendicular to said cross-sectional image to generate a second two-dimensional data set in said memory representative of a longitudinal image of a yarn including said bundle of fibers;
- and
- displaying with said control system said longitudinal image of a yarn on said display device.
In a computer-assisted design system having a data storage memory, a display device for displaying an image corresponding to a data set in said memory and a logic control system for manipulating data, a method for generating an image of a textile article comprising:
- providing in said memory a first data set representative of a first yarn;
- providing in said memory a second data set representative of a second yarn;
- providing in said memory a third data set representative of a weave matrix including parameters for generating a woven fabric;
- combining with said control system said first and second data sets according to said third data set to produce a fourth data set representative of a woven fabric image having shading at portions of yarns in said image according to a function that is dependent on parameters of an element in the weave matrix that corresponds to the one of said portions;
- and
- displaying with said control system said woven fabric image on said display device.
A computer-assisted design system apparatus for generating an image of a textile article comprising:
- input means for receiving a user selection of fiber arrangement in a lateral cross section of a yarn;

- and
- woven fabric image generating means for applying a set of weave pattern parameters to said yarn image generating means to generate an image of a fabric woven according to a weave pattern utilizing a yarn image generated from a user selection to said input means.
A computer-assisted design system apparatus for generating an image of a textile article comprising:
- yarn data storage means for storing data representative of a plurality of yarn designs;
- weave matrix data storage means for storing parameters sufficient to specify a weave pattern;
- and
- woven fabric image generating means for applying a set of weave pattern parameters to sets of yarn design data to generate an image of a fabric woven according to a weave pattern utilizing yarn represented by said sets of yarn design data, said woven fabric generating means including yarn shading means for individually shading portions of yarn in a woven fabric image.
