Abstract(s)
The generation of three-dimensional plant models is increasingly important for applications
in agriculture, scientific visualization, landscape design, and immersive virtual
environments. Existing approaches often rely on specialized hardware or sensor data,
and publicly available models are limited, repetitive, or constrained to specific species,
limiting creative flexibility. This dissertation addresses these challenges by focusing
on sketch-based plant modelling as an accessible and flexible approach.
A systematic review of state-of-the-art methods was conducted following the Preferred
Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) guidelines,
identifying two main directions: sketch-based modelling and tree generation
from photographic data. Insights from this review informed the design of a novel
framework that integrates single- and multi-sketch strategies to generate 3D plant models
from user drawings. The framework was implemented as a Blender add-on, supporting
features such as variable levels of detail, leaf propagation, and generation of
multiple model variations, while providing a streamlined and intuitive interface.
The add-on was evaluated through quantitative and qualitative analyses. Task completion
times demonstrated efficient modelling, and a mean System Usability Scale
(SUS) score of 56.4 indicated moderate usability. Correlations with demographic factors
revealed influences of user experience, background, and familiarity with input devices
on usability. Qualitative feedback highlighted areas for improvement in feature
intuitiveness and onboarding. Despite a limited and unevenly distributed participant
sample, the results indicate that the framework is a promising tool for procedural plant
modelling and can enhance creative workflows for users of varying expertise.
This work contributes both a systematic understanding of visual-based plant modelling
approaches and a practical tool that bridges sketching and 3D model creation,
providing a foundation for future enhancements such as AI-assisted sketch interpretation,
expanded plant element support, and improved interface features.
