Visualization and modeling of textile materials has already been inves
tigated In detail in the computer graphics literature, Most of the wor
k, however, concentrates on woven fabrics, In this paper we present a
novel approach to the modeling and rendering of knitwear, After the to
pological specification of a knitting pattern a subdivision into basic
elements is done, The yam microstructure within basic elements is app
roximated by volume data sets. The repetitive structure of knitted fab
rics allows an efficient rendering technique. Resulting images are giv
en that demonstrate the feasibility of our approach.
