LIGHTING AND MODEL RENDERING WITH IMPORTED GEOMETRY IN ASSEMBLY UNITS OF DIGITAL PRODUCT LAYOUTS
The approaches that provide object's illumination and visual representation of models as a part of the assemblies are considered. Digital layouts of assembly units, which are represented by export data formats in modeling systems, are used as initial object models. To substantiate the development of the software module, a structural description of the design solution for high quality display of models with photorealistic features was prepared. A software solution was created that provides functionality to visualize and display models as part of an assembly with effects that correspond to the conditions of behavior of objects in the real world. The software module in the implementation of rendering of models, which are part of the imported assemblies, is made on the classes and methods of the open geometric kernel Open CASCADE, where through dialogs, as well as with the help of auxiliary elements, visualization and lighting of object surfaces is made. Besides, the software implements tools for viewing and representing models in a separate scalable window, has functionality for changing model colors, deleting individual models in the assembly, shows the composition of the imported assembly if the specified records are placed in the export data format. The development is prepared for use in the Linux Manjaro operating system based on 64-bit architecture
