Abstract: Three-dimensional (3D) morphology is an important physiological characteristic of plants. In particular, because of its close link to the efficiency of photosynthesis, 3D morphology is an important tool for the investigation of plant growth. In 2014, 56 bryophyte specimens were collected near Great Wall Station on George King Island, Antarctica. The specimens were identified as four families, six genera, six species, and one variety. Representative samples were selected from each species and 3D morphology was determined using high precision laser scanning. The system harvested 120 million point cloud data points, as well as 987,429 points and 1,700,380 surfaces, to reconstruct the 3D morphological surfaces of seven plant species. In addition, Java Web technologies, MySQL, Three.js, and Tomcat, were used to build a domestic database (3D MPP, 3dmpp.gznu.edu.cn) of the 3D morphology of Antarctic plants, according to the WebGL standard with 3D rendering function. Using this database, researchers can browse and search for species information and can obtain access to the 3D morphological information. Furthermore, the database offers the option to download these 3D files in STL file format. The database offers a platform for the storage, display, and sharing of 3D morphological information of polar plants and provides basic data and tools for the comparative study of the 3D surface morphology of these plants. It also provides important protection for holographic information on polar plants.
