Windy trees: computing stress response for developmental tree models
ACM Transactions on Graphics (TOG), Volume 33, Issue 6Article No.: 204, Pages 1–11https://doi.org/10.1145/2661229.2661252We present a novel method for combining developmental tree models with turbulent wind fields. The tree geometry is created from internal growth functions of the developmental model and its response to external stress is induced by a physically-plausible ...

Capturing and animating the morphogenesis of polygonal tree models
ACM Transactions on Graphics (TOG), Volume 31, Issue 6Article No.: 169, Pages 1–10https://doi.org/10.1145/2366145.2366188Given a static tree model we present a method to compute developmental stages that approximate the tree's natural growth. The tree model is analyzed and a graph-based description its skeleton is determined. Based on structural similarity, branches are ...

ACM Transactions on Graphics (TOG), Volume 31, Issue 4Article No.: 50, Pages 1–10https://doi.org/10.1145/2185520.2185546We present a dynamic tree modeling and representation technique that allows complex tree models to interact with their environment. Our method uses changes in the light distribution and proximity to solid obstacles and other trees as approximations of ...

Efficient modeling of numerous trees by introducing growth volume for real-time virtual ecosystems
Computer Animation and Virtual Worlds (CAVW), Volume 23, Issue 3-4May 2012, Pages 155–165https://doi.org/10.1002/cav.1438This study suggests a growth volume system for the efficient modeling of numerous trees for a real-time virtual ecosystem. To increase the efficiency of the real-time system and to allow natural tree generation, the basic tree modeling system obtains ...

Modeling trees with a space colonization algorithm
NPH'07: Proceedings of the Third Eurographics conference on Natural PhenomenaSeptember 2007, Pages 63–70We extend the open leaf venation model by Runions et al. [RFL*05] to three dimensions and show that it generates surprisingly realistic tree structures. Model parameters correspond to visually relevant tree characteristics identified in landscaping, ...
