The system utilizes virtual texture, block scheduling and other technologies to solve database building, management, scheduling and distribution of big 3D data, making it possible for 3D virtual reality system to develop from single application system to system integration. It is able to present the overall look of agricultural park from the macro level, and describe the operational state of equipment inside the greenhouses as well as data parameters from the micro level, so as to help users get the information they need in an explicit, vivid and efficient way. The combination of 3D technology and agricultural informatization is another innovation of KQ GEO in the field of modern agriculture.
