Abstract: Method for simulating a dyed fabric, in which an image of the dyed fabric is produced on a display device, such as a color monitor, or on a hardcopy. The fabric to be simulated consists of dyed yarns woven into each other which each consist of interrupted pieces of particular shape at the surface perceptible to the eye. The colors of all the points in the total surface of each simulated shape are summed and corrected so that the average color is approximately the same as the spectrophotometrically measured color of the shape of the fabric in reality, The simulated shape is embodied in a manner such that it is approximately the same as the shape of the yarn which the eye will observe when observing the fabric in reality and which is provided with shading at the edges when it passes over and beneath other yarns. For the purpose of defining the position of the surface of the simulated shape in the three-dimensional space, the shape is chosen as an elliptical shape between two yarns passing thereover.
