Abstrakt:
Trees are among the most visually appealing and complex structures in Nature. They have immeasurable effects on humans as they are an essential part of the atmosphere, but they also have substantial positive value on our well-being. Computer science has attempted to capture and decipher the shape and development of trees for over forty years, with one of the goals being to build tree digital twins – a computer representation that responds to its environment, is simulation-ready, and can be used to answer "what-if" scenarios.

This presentation will showcase several recent advances enabled by the deep neural representation of mathematical models of trees, including their development. We will show how tree representations can be learned from data, particularly vegetation capture using LiDAR or single images. We will discuss how L-systems can be learned by the transformer and how a novel deep representation can encapsulate the tree's environmental and growth parameters by learning them from simulated data.  We will also present several recent methods that combine physics to illustrate the dynamics of plant growth and its interaction with the environment.
