The goal of the project was to develop a solution for a system able to transmit over the internet and visualise a huge amount of geometric data for making flying over in real time. Today’s communication canals do not allow transmission of a large data set in a real time, and besides this, visualisation of such amount of data can cause additional problems. The proposed solution consists of three steps: data preparation (presenting data with a triangular mesh, mesh decimation, data division into several resolution models, compression of these models), data transmission from a server to a client, and receiving the data on the client’s side and their visualisation. It was proved right that relatively low throughput of the communication canal in the presented solution already enables transmission and visualisation of huge geometric data sets in real time.
