Abstract

Motivation

With the development of computer graphics in front-end technology and internet applications, there are many universal online modeling tools like Spline and Vectary. However, ship hull design requires specific constraints like displacement volume and standard deformation algorithms such as Lackenby and Free-Form deformation (FFD).

Solution

This study developed an online platform of ship hull parametric modeling and design called Ship Hull Iterative Parametrization Online (SHIP Online). Firstly, three deformation methods—linear,interactive FFD, and combined deformation—were implemented using JavaScript and Python. Fast Quadric Mesh Simplification (FQMS) and Nelder-Mead optimization were introduced for combined deformation. Secondly, the user interface was built with HTML5, JavaScript, and CSS. Thirdly, the synchronization and data transmission issues between front and back-end were handled by Django and $. ajax. Finally, the platform would be deployed on a cloud server for multi-system access.

Result

The DTMB-5415 standard model was used to evaluate the accuracy, efficiency, and functions of calculations and deformations in SHIP Online. The errors of hydrostatic parameters were nearly 0.0 %. With a 90 % optimal simplification rate and parameter errors under 0.001, combined deformation efficiency improved by 87.78 % and 55.15 % compared to deformation without FQMS and other software. Functional and user testing shows that the functions can be stably and normally executed.

Conclusion

By integrating ship deformation algorithms and design constraints with the front-end technology, SHIP Online provides a Web-based rapid hull design platform instead of traditional 3D modeling client software.
