The display of target data such as casting defects is an important part of 3D data field visualization of numerical simulation software. At this time, if the solid display of sand castings is used, the user cannot see the target data inside the contour. If the target data such as defects are displayed separately, the user cannot determine its specific location.
In the visual display, the user is really concerned about the display of the target data, but the outer contour of the sand casting must also be displayed. In order to facilitate the user to observe the relative position of the target data in the sand casting, at this time, the display of the target data and the outer contour of the sand casting is shown in the figure:
