We present a hardware-based, volumetric approach for rendering
knit wear at very interactive rates. A single stitch is
represented by a volumetric texture with each voxel storing the
main direction of the strands of yarn inside it. We render the
knit wear in layers using an approximation of the Banks model.
Our hardware implementation allows specular and diffuse material
properties to change from one voxel to the next. This enables us
to represent yarn made up of different components or render
garments with complicated color patterns. Furthermore, our
approach can handle self-shadowing of the stitches, and can
easily be adapted to also include view-independent scattering.
The resulting shader lends itself naturally to mip-mapping, and
requires no reordering of the base geometry, making it
versatile and easy to use.
