Let Every Tree Have Its Own Life
Reconstructing Nature Through Procedural Systems
A Geometry Nodes–based parametric vegetation system designed for precise morphological control and real-time response to physically driven wind fields.
In this project, we move beyond the traditional boundaries of modeling and animation.
Built entirely within Blender Geometry Nodes, and grounded in Cosserat rod–based physical constraints, we developed a fully procedural, dynamically solvable, high-performance tree system capable of generating cohesive and believable natural environments.
Procedural Vegetation System
From Parameterization to Species Variation
Flexible Morphological Control
Through an intuitive parameter-driven system, we can precisely control:
* species variation
* canopy structure
* branching hierarchy
* curvature behavior
* density distribution
Subtle parameter adjustments allow for a wide range of plant variations while maintaining full non-destructive control. The system also supports art-directable adjustments at every hierarchical level of the branching structure.
All vegetation UVs are generated through a fully procedural UV workflow.
Additionally, the internal branching system is built upon a topology-aware curve data structure, providing a stable foundation for downstream physical simulation with believable details.
Geometry Nodes–Based Dynamics System
Physically Driven Wind Simulation
Continuum Mechanics–Based Branch Dynamics
Within Geometry Nodes, we developed a line-based solver derived from Cosserat rod theory, enabling physically plausible simulation of branch behavior under wind forces.
The system accurately reproduces:
* bending
* torsion
* elastic recovery
* collision response
* plastic deformation
Wind Field Control & Layered Response
The system supports full control over:
* wind direction
* wind intensity
* turbulence
* gust frequency
Different regions of the tree respond hierarchically based on variations in branch length and stiffness, resulting in highly natural and believable motion.
Production-Oriented System Design
The entire system is designed with a focus on usability, parameter control and scalability. This ensures efficient adaptability across a wide range of production scenarios.
Real-Time Simulation & Pipeline Integration
Dynamic simulations can be previewed in real time directly within the Blender viewport.
The results can be baked into keyframe animation on a per-frame basis and seamlessly exported to any standard rendering and compositing pipeline.
