摘　　要：针对传统的脚本建模存在语言机制复杂繁琐、开发效率不高、可靠性难保证、建模阶段和交互阶段相互独立等问题,基于分划与递推(PAR)及其Apla抽象程序设计语言,设计与原Apla语言融合的虚拟现实建模语言机制。开发的Apla→MAXScript自动生成系统可以将抽象Apla程序转换成MAXScript脚本,并借助3DSMax来实现三维建模。Apla建模机制采用直接重用MAXScript修改器API方式,既大幅度简化了重构的工作量,又延续了Apla语言抽象程度高特征,便于对Apla建模程序进行形式化推导和正确性验证。最后通过案例证明了Apla建模语言及其工具能够提高三维建模的精细度、可靠性及开发效率。Aming at the problems such as being too complicated and cumbersome language mechanism,low efficiency,difficult reliability,independent modeling and interactive phases in the traditional script modeling,a virtual reality modeling language mechanism integrated with Apla language was designed based on the original research results of PAR(partition and recurrence)method platform and the Apla abstract programming language. The Apla→MAXScript automatic generation system could convert the abstract Apla program into a MAXScript script,which could be used to implement 3D models by 3DSMax.The designed Apla modeling mechanism directly reused the MAXScript modifier API,which not only greatly simplifies the workload of reconstruction,but also maintains the high abstraction feature of the Apla language. Meanwhile, the designed Apla modeling mechanism is convenient for formal derivation and verification of the Apla modeling program. It is exemplified by the case that our Apla modeling language and its tools can improve the precision,reliability and development efficiency of 3D modeling.
