Virtual crop models and animation make great significances to agricultural researches. But to recreate the structure and dynamic is often a hard and laborious task. Most existing plant-modeling systems require the user to have specific biological knowledge about plants, but its often the 3D artists who do the work. This paper discusses a method of plant modeling and rigging in Maya, which has already been familiar to 3D artists and has advantages in industrial production pipelines. The method takes pepper plant for example, dividing the problem into organs and the growth patterns, and using Maya modeling and animating system to simulate the topological structure and growth dynamic. It set up the geometry with controls which are easy to use. The result can be conveniently exported to projects. This approach helps prepare the research of variety plant modeling and animation plug-in for Maya.

This paper describes the concept of reverse engineering and the workflow of reverse modeling software — imageware. Using the powerful function of point cloud data processing in imageware, it achieves point cloud data pre-processing, point cloud segmenting, contour curve fitting and surface reconstructing of the human body. Finally, it makes the error evaluation of the surface model. This study may provide original design basis for related research.

With the social mass production of garment industry, the same style clothing requires organizing production in various specifications or size series to meet the different needs of consumers. Fast, accurate and flexible automatic grading technology has become the research hotspot, and the scientific size table is the basis of this technology. This study collects the size data of 251 female college students. Then make the body type classification and gain the size table of intermediate type and the increment of each body type. This study provide the basis for MTM automatically parameter table of young female university students to establish a pattern grading system.
