Visualizing, Analyzing and Constructing L-System from Arborized 3D Model Using a Web Application
International Joint Conference on Biomedical Engineering Systems and Technologies(2024)
摘要
In biology, arborized structures are well represented and typically complex
for visualization and analysis. In order to have a profound understanding of
the topology of arborized 3D biological model, higher level abstraction is
needed. We aim at constructing an abstraction of arborized 3D biological model
to an L-system that provides a generalized formalization in a grammar to
represent complex structures. The focus of this paper is to combine 3D
visualization, analysis and L-system abstraction into a single web application.
We designed a front-end user interface and a back-end. In the front-end, we
used A-Frame and defined algorithms to generate and visualize L-systems. In the
back-end, we utilized the Vascular Modelling Toolkit's (VMTK) centerline
analysis methods to extract important features from the arborized 3D models,
which can be applied to L-system generation. In addition, two 3D biological
models: lactiferous duct and artery are used as two case studies to verify the
functionality of this web application. In conclusion, our web application is
able to visualize, analyse and create L-system abstractions of arborized 3D
models. This in turn provides workflow-improving benefits, easy accessibility
and extensibility.
