Real adaptive topography optimization algorithm based on injection simulation platform

To meet the requirements of some injection simulation platforms for reality, a real adaptive topography optimization algorithm based on Real Time Optimally Adapting Mesh (ROAM) algorithm was proposed. By taking the terrain generated by ROAM as a base grid, a new integrated parameter Y was proposed, and a given threshold was compared with the Y parameter to determine whether the local splitting was implemented or not. The sharp features of the terrain were extracted from a vertex that satisfy the splitting conditions, and the local curve surface was splitted by Loop algorithm. Finally, a video stream was generated by rotation mapping algorithm in real-time roaming process and it was sent to the injection simulation system to be displayed by a Digital Visual Interface (DVI) display. Experimental results show that the average of roaming frame rate of proposed algorithm is 45.1303 frame/s and the peak frame rate is close to 50 frame/s, higher than that of traditional algorithm. Moreover, the obtained terrain could display on the DVI display on the injection simulation platform with an average of roaming frame rate of 45 frame/s, which satisfies the requirements of the injection simulation systems for the reality.
