Embodiment Construction
[0033] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
[0034] figure 1 Select the way schematic for the prior art model. In the existing technology, when a click event is triggered, a collision detection ray is launched from the click point to multiple 3D models; when the ray hits the model, the first model it touches or the earliest touched Model name, and stop collision detection so that the model is selected. However, it is difficult for users to select the object model they want to select when the models are relatively small, clustered together or overlap with each other, especially when the model is blocked or there are a lot of other models around. At this time, There may be multiple misclicks, or other models must be moved or rotated to select, or even the target model cannot be selected at all. At the same time, using the traditional method, one ray can only select one detected model at a t...
