Abstract

An overview of the development of a stereolithography preprocessor for constructing wire frame images for model verifications is presented. Based on the data representation in stereolithography files, the preprocessor is designed to consist of four subsystems-data input in both ASCII and binary format, wire frame images construction, interactive verifications and data output in both ASCII and binary format-so as to enable visualisation of the stereolithography model and geometrical orientation of the model. The design allows the user to optimise part orientation for the stereolithography process. The preprocessor has been evaluated to be fully functional and versatile with an excellent graphics display for the model
