Popis: Creating vegetation contents for a digital twin city entails generating dynamic 3D plant models in a large scale to represent the actual vegetation in the city. To enable high-fidelity environmental simulations and analysis applications, we model individual trees at a species level of detail. The 3D models are generated procedurally based on their botanical species profiles within the constraints of measurements and growth spaces derived from laser-scanned point cloud data. Users can conveniently define the known profile of a species by using a species profile template that we formulated based on species growth processes and patterns. Based on the given species profile and solving for the unknowns within the growth space constraints, a species model will be grown through iterations of our formulated growth rules. We show that this methodology produces structurally-representative species models with respect to their actual physical and species characteristics.
