Abstract: A process of determining features of a fabric. A representation of a portion of a surface of the fabric is formed showing locations and sizes of knuckles and pockets in the fabric surface. The representation is a print or a photograph of the fabric surface. An image is generated based on the representation. At least a portion of the image is displayed on a computer screen. The sizes and locations of the knuckles or pockets is determined. A unit cell is drawn for the portion of the fabric surface in the image. The unit cell is defined by guidelines that (i) pass through the centers of the knuckles and (ii) form shapes that surround areas of the image that correspond to where the pockets are formed between the knuckles. A fabric planar volumetric index is calculated based on properties of the unit cell formed by the guidelines.
