Interactive Invigoration: Volumetric Modeling of Trees with Strands
Abstract
Generating realistic models of trees and plants is a complex problem because of the vast variety of shapes trees can form.
Procedural modeling algorithms are popular for defining branching structures and steadily increasing their expressive power by considering more biological
findings. Most existing methods focus on defining the branching structure of trees based on skeletal graphs, while the surface mesh of
branches is most commonly defined as simple cylinders. One critical open problem is defining and controlling the complex details
observed in real trees. This paper aims to advance tree modeling by proposing a strand-based volumetric representation for tree models.
Strands are fixed-size volumetric pipes that define the branching structure. By leveraging strands, our approach captures the lateral
development of trees. We combine the strands with a novel branch development formulation that allows us to locally inject vigor and
reshape the tree model. Moreover, we define a set of editing operators for tree primary and lateral development that enables users to
interactively generate complex tree models with unprecedented detail with minimal effort.
