A distributed graphics programming language called DGLa is presented, which facilitates the development of distributed graphics application. Facilities for distributed programming and graphics support are included in it. It not only supports synchronous and asynchronous communication but also provides programmer with multiple control mechanism for process communication. The graphics support of DGLa is powerful, for both sequential graphics library and parallel graphics library are provided. The design consideration and implementation experience are discussed in detail in this paper. Application example are also given.
