According to various embodiments of the present invention, an optical capture system is provided. In one embodiment, a micro-scale optical capturing system is provided with low divergence (approximately 1°) of the incident light and low acceptance angle (<8°) of the captured light. According to embodiments, a micro-scale optical capturing system is provided with a large number of collimated high-power white LEDs as light sources, between 60 and 100 units, for example, and may be positioned at distances of about 650 mm from the sample. In one embodiment, a digital camera using 50 mm focal objective with a 25 mm length extension tube captures images of the sample. This provides a working distance of approximately 100 mm and at the same time maintains ×0.5 magnification for microscale captures, with an image size of 4×4 microns per pixel.

Modeling cross-sections of yarn may include receiving yarn simulation input comprising a descriptive model of a general curvature followed by the yarn, providing a plurality of fibers distributed radially from the center of a ply, setting a base position based on parameters, applying a strain model to simulate the effect of stretch forces applied to the yarn, and outputting a yarn model indicating position and directionality of fibers in the yarn. The technology also relates to real-time modeling of a garment comprising a fabric. For instance, real-time modeling of a garment may include providing an input associated with one or more parameters of the fabric, receiving frames of a computer simulated garment, the computer simulated garment including a simulation of the fabric, the fabric simulation including yarns simulated based on a yarn model.
