T=rand (ta, tb)；
As it can be seen that specifically calculating step for the required model animation duration are as follows: from previous uterine contraction duration and
A numerical value is randomly selected between the two duration values of phase duration of having a rest as the required model animation duration；That is, right
It is the uterine contraction duration ta from the previous uterine contraction period in the required model animation durationn-1With intermittent phase duration tbn-1
It is randomly selected out between the two numerical value；
S20143, model of place presentation quantitative model is established, this model is used to press according to uterine contraction curve instantaneous slope and palace
Value, so that model of place number be calculated；
Specifically, the number of model is related with contraction strength in scene, therefore when uterine contraction is stronger, and more models is enabled to go out
It is existing, meanwhile, in order to allow animation more vivid and interesting, the number of model can also be reduced with the decrease of contraction strength, that is,
It says, the number of model of place is in the state of a dynamic change；In order to meet this demand, in the present embodiment (such as Fig. 4 institute
Show), the model of place of required building is presented quantitative model and is particularly preferred as: N=γ k+ δ m；Wherein, N is expressed as model of place number
