Realistic and efficient rendering of free-form knitwear
نویسندگان
چکیده
We present a method for rendering knitwear on free-form surfaces. Starting from a parametric surface, a stitch pattern, and optionally a color pattern, we can produce highly realistic rendering of knitwear efficiently. Our method draws its realism from two sources. First, we have developed a novel and sophisticated model for free-form knitwear that takes into consideration the interactions between neighboring loops and the subtle irregularities in the position of the loops. Second, we have derived a method for rendering yarn microstructure with user control of the fluffiness of the yarn. The efficiency of our method comes from the fact that it displays free-form knitwear as Gouraud-shaded polygons, which current graphics hardware is optimized to draw. In contrast, previous technique for rendering free-form knitwear requires tracing curved rays and therefore cannot benefit from massmarket graphics hardware.

متن کاملParticle-based simulation of the interaction between fluid and knitwear
We present a particle-based method to simulate and visualize the interaction of knitwear with fluids. The knitwear is modeled using spring-mass systems and the fluid is modeled using the smoothed particle hydrodynamics method. Two-way coupling is achieved by considering surface tension, capillary, and interparticle forces between the fluid and knitwear. The simulation of fluid and knitwear part...

The yarnmicrostructurewithin...
متن کاملReal-time Cloth Rendering with Fiber-level Detail.
Modeling cloth with fiber-level geometry can produce highly realistic details. However, rendering fiber-level cloth models not only has a high memory cost but it also has a high computation cost even for offline rendering applications. In this paper we present a real-time fiber-level cloth rendering method for current GPUs. Our method procedurally generates fiber-level geometric details on-the-...
