Especially for complex industrial plants, which may consist of thousands of pipes, the monitoring of the operating physical conditions is a very cumbersome process. The complexity of the equipment object, especially the variable parameter characteristics such as elbow, welding seam, material and the like, brings huge workload to the three-dimensional modeling of the equipment object.
In the use process of the complex pipeline system, the physical states of the pipeline, such as temperature, pressure and the like, cannot be observed and sensed intuitively by equipment operation and maintenance personnel, which brings great challenges to the operation and maintenance of the complex pipeline system. The inconsistency between the physical model and the state parameters of the equipment object brings difficulty to the corresponding display of the physical and the parameters of the equipment object.

The complexity of the device object poses challenges to the method of device object presentation. The device appearance is to be described on the device object.

The three-dimensional modeling software adopts a three-dimensional entity or a three-dimensional space curved surface to represent the space form of a real design pipeline, and then the state of the pipeline is rendered onto the entity or the curved surface by different colors. This method requires a large amount of computer CPU computation, and is too costly to implement, especially for complex industrial pipeline systems.
