  • Publication number: 20250087092
    Abstract: Disclosed are a three-dimensional (3D) simulation method and a 3D simulation apparatus. The 3D simulation method disclosed herein includes a step (S20) of separating point cloud data including a road, an obstacle, and a cargo transportation route into road data and obstacle data, a step (S40) of converting the road data into road mesh data, and converting the obstacle data into obstacle mesh data, a step (S60) of constructing a virtual environment by merging the road mesh data with the obstacle mesh data, a step (S80) of loading a specific cargo transportation route to the virtual environment, a step (S100) of loading a 3D transport truck and a 3D cargo to a predetermined point of the cargo transportation route, and a step (S120) of performing a route survey simulation while virtually driving the 3D transport truck and the 3D cargo along the cargo transportation route.

  • Publication number: 20250040594
    Abstract: A cigarette filter which includes lyocell tow made of a plurality of lyocell fibers and a binder configured to bond the lyocell fibers to each other is provided. The cigarette filter according to one embodiment of the present disclosure reduces each of tar and nicotine, which are delivered through cigarette smoke, by 70% to 95%. The cigarette filter according to one embodiment of the present disclosure has a resistance to draw of 80 mmWG to 200 mmWG. The cigarette filter according to one embodiment of the present disclosure is filled with the lyocell tow at a packing density of 0.2 g/mL to 0.6 g/mL. The cigarette filter according to one embodiment of the present disclosure addresses basic material-related problems, such as low hardness, of the lyocell tow and, further, has excellent filtration functionality as a filter.
