Embodiment Construction
[0013] Examples are given below to describe the present invention in detail.
[0014] The invention provides an object-oriented hoisting process flow simulation modeling method. Firstly, a general simulation class is constructed to provide public functions. Proprietary functions of respective hoisting movements; build hoisting classes by inheriting simulation classes, provide exclusive functions for driving driving, crane, rope and hook objects, and collaboratively realize the hoisting process.
[0015] In order to be able to control the motion of various simulation objects in the virtual scene, it is first necessary to establish a mapping between various simulation objects and the simulation model to be operated in the program. The way of mapping is to use the pointer of the transformation matrix MatrixTransform type provided by OSG (OpenSceneGraph) to point to the simulation model that needs to be mapped. When mapping the root node of the simulation model, it is possible to...

Description
technical field [0001] The invention relates to the technical field of process flow simulation, in particular to an object-oriented hoisting process flow simulation modeling method. Background technique [0002] The process simulation is to find problems and optimize the process. Usually, 3D simulation drills are carried out according to the predetermined process plan. Next, either modify the shortcomings of the predetermined plan, or generate new ideas to design a new plan, and finally through the comparative analysis of multiple plans Determine the best solution. It is not difficult to see that whether the simulation drill of various process schemes can be quickly completed in the whole process is the key to determine whether the process simulation can play a role. [0003] The existing process simulation method is mainly based on data-driven, and its main drawback is that the data changes in some key steps in the simulation program are likely to cause chain reactions in ...
