Message to Students

In 3D Graphics Laboratory, we mainly research about the measurement by image processing, and try to develop the method and equipments to realize the resolution power of 1/200000 of image width/height. This resolution corresponds to 5mm in Skytree height. Another research activity is development of 3D solid modeler for the educational use. Full source codes are develpoed in the laboratory, and now it is used at 5 to 10 universities for the education of descriptive geometry..
