Abstract

This study focuses on the spatial fluctuations of garden foliage in the wind. It differs from previous spatial analyses of static structures in traditional Japanese gardens. This study was conducted using 3D point cloud data and verified with a dynamic state detection method via analyzing the spatial distribution of fluctuating foliage at Tanpu-kei in Shosei-en Garden, Kyoto, Japan. 3D measurements were taken three times to detect the fluctuating point cloud (F-point cloud), continuously fixed point cloud (C-point cloud), and total point cloud (T-point cloud). The data was taken using standard parameters; the appropriate voxel size is 0.125 meters, and the right cubic unit size for the spatial analysis is 1 cubic meter. As a result of spatial analysis with this appropriate value, in the vertical distribution, the T-point cloud number decreased in the upper layers except for 1.5-2.5 meters, and the F-point cloud percentage increased. Locations with strongly fluctuating foliage were distributed along the garden path at 1.5-2.5 meters in the horizontal distribution. This study detected spatial fluctuation in the dynamic movement of garden foliage and established a method to capture the dynamics of fluctuation.
