On the Statistical Analysis of Complex Tree-shaped 3D Objects [article]

Guan Wang, Hamid Laga, Anuj Srivastava
2021 arXiv   pre-print
The framework is also applied to various shape analysis tasks: (i) symmetry analysis and symmetrization of tree-shaped 3D objects, (ii) computing summary statistics (means and modes of variations) of populations  ...  of tree-shaped 3D objects, (iii) fitting parametric probability distributions to such populations, and (iv) finally synthesizing novel tree-shaped 3D objects through random sampling from estimated probability  ...  We can clearly see that sampling from the probability distribution fitted to the input population allows the synthesis of rich 3D botanical tree models and neuron tree shapes.  ...

3D modeling and reconstruction of plants and trees: A cross-cutting review across computer graphics, vision, and plant phenotyping

Fumio Okura
2022 Breeding Science  
This paper reviews the past and current trends of three-dimensional (3D) modeling and reconstruction of plants and trees.  ...  Representations of plant shape and structure are first summarized, where every method for plant modeling and reconstruction is based on a shape/structure representation.  ...  In fact, an early attempt of multiview 3D reconstruction of botanical trees (Shlyakhter et al. 2001) unified the 2D and 3D cues.  ...

Interactive Design of Botanical Trees using Freehand Sketches and Example-based Editing

Makoto Okabe, Shigeru Owada, Takeo Igarash
2005 Computer graphics forum (Print)  
We present a system for quickly and easily designing three-dimensional (3D) models of botanical trees using freehand sketches and additional example-based editing operations.  ...  The system generates a 3D geometry from a twodimensional (2D) sketch using the assumption that trees spread their branches so that the distances between the branches are as large as possible.  ...  Introduction 3D models of botanical trees are important in geographical landscape simulation, cityscape design, virtual reality, consumer games, and other fields of 3D graphics.  ...

Tree Modeling with Real Tree-Parts Examples

Ke Xie, Feilong Yan, Andrei Sharf, Oliver Deussen, Hui Huang, Baoquan Chen
2016 IEEE Transactions on Visualization and Computer Graphics  
In the modeling process, tree-cuts are positioned in space in an intuitive manner, serving as efficient proxies that guide the creation of the complete tree.  ...  We introduce a 3D tree modeling technique that utilizes examples of real trees to enhance tree creation with realistic structures and fine-level details.  ...  ACKNOWLEDGMENTS The authors thank all the reviewers for their valuable comments and constructive suggestions. They are grateful to Jianwei Guo for his help on tree rendering.  ...

Structure from silhouettes: a new paradigm for fast sketch-based design of trees

J. Wither, F. Boudon, M.-P. Cani, C. Godin
2009 Computer graphics forum (Print)  
When the user finally zooms out, the style inferred for the branching systems he has refined (in terms of branch density, angle, length distribution and shape) is duplicated to the unspecified branching  ...  Meanwhile, knowledge from botany is again used for extending the branch distribution to 3D, resulting in a full, plausible 3D tree that fits the user-sketched contours.  ...  We build such a structure based on botanical knowledge of trees, as presented in §3. Our method for recursively refining the tree shape and copying the style to the non-refined parts is given in §4.  ...

Modeling Complex Unfoliaged Trees from a Sparse Set of Images

Luis D. Lopez, Yuanyuan Ding, Jingyi Yu
2010 Computer graphics forum (Print)  
Our solution directly integrates 2D/3D tree topology as shape priors into the modeling process.  ...  Existing tree modeling tools either require capturing a large number of views for dense 3D reconstruction or rely on user inputs and botanic rules to synthesize natural-looking tree geometry.  ...  We would like to thank the anonymous PG reviewers for their valuable comments and suggestions. The authors are supported in part by NSF grants MSPAMCS-0625931, IIS-CAREER-0845268 and CONA-CYT 171570.  ...

Reconstructing 3D tree models from instrumented photographs

I. Shlyakhter, M. Rozenoer, J. Dorsey, S. Teller
2001 IEEE Computer Graphics and Applications  
The first rule directs the elongation of existing branches with time. The second rule allocates the creation of new branches from a bud, and the development of new buds on the existing branches.  ...  We're grateful to Ned Greene, who promptly replied to our request for one of his papers, and to Neel Master for his help with determining camera poses.  ...  Each cone restricts the 3D tree to lie inside it, so by computing the 3D intersection of all cones, we get an approximation to the 3D tree shape. We depict this process in Figure 2 .  ...

In the middle, a possible architecture of the branching extracted with our skeletonisation method. On the right, a 3D model of this tree with the same viewpoint.  ...  Then, a 3D generative model, based on a parametric model of branching systems that takes into account botanical knowledge is built.  ...  Based on botanical expertise, we assume that different branches of relatively similar size coexist and share the space of the crown of a plant.  ...
