Filling arbitrary shapes with tilted gratings


In manufacturing devices of virtual reality and augmented reality, it is always involved that tilted gating is fabricated in specific area. In common methods, when grating line is rotated or fractured, line ending and fractured shape border would be snapped into unexpected grid intersection in database. The issue can be solved by a simple BEAMER flow and it is user-friendly to customize.


The BEAMER flow includes Import and Python modules. User can import contour which grating need populating in Import module and define features of the grating in Python module. Based on the defined grating parameters, single tilted line is created and repeated within the subfield and then mainfield. At last, the border of the entire grating area is decided by layout imported in Import module.
