  • Publication number: 20240102214
    Abstract: The present application relates to control command generation methods and systems for three-dimensional surface weaving. The control command generation method comprises the steps of: rebuilding a desired three-dimensional object into a three-dimensional surface mesh; converting the three-dimensional surface mesh into readable weaving information; and generating control commands from the readable weaving information to instruct a three-dimensional surface weaving system. The control command generation method generally comprises a pipeline of software including the mesh processing, weaving map extraction and command generation. The control command generation method can enable three-dimensional surface weaving function.

  • Publication number: 20240102213
    Abstract: The present application relates to systems, devices and methods for three-dimensional surface weaving. The system comprises a jacquard device, a weaving device and a roller matrix. The jacquard device configured to selectively raise or lower the wrap threads to form a shed for the weft thread to travel; the weaving device configured to carry the weft thread into the shed and weave the weft thread on the wrap threads; and the roller matrix with individually controlled rotate apparatus configured to control the wrap threads to move forward or backward. The wrap threads come from rotate apparatus installed on the roller matrix. The rotate apparatus is controlled individually to forward or reverse rotate, so that the attached wrap thread is able to be longer or shorter. As the wrap threads can be shortened during weaving process, the three-dimensional surface can be produced.

  • Patent number: 8411090
    Abstract: Disclosed is a method for flattening a 3D surface into a 2D piece. In one embodiment, the method is implemented by constructing a plurality of wire-patches by feature curves on a surface patch of the 3D surface, wherein each of feature curves comprises a plurality of wire-nodes; computing an optimal 2D angle for each of said wire-nodes of the constructed wire-patches; determining an optimal position for each of said wire-nodes based on the computed optimal 2D angles thereof, respectively; and laying out each of said feature curves in 2D based on the determined optimal position. A device to flatten a 3D surface into a 2D piece is also provided.
