Abstract. In this paper, a three-dimensional (3D) visualization method of poplar seedlings was proposed, combined with the ToF camera and digital camera. Firstly, the average distance density method was proposed and employed to process outlier of leaves. Secondly, in order to improve the speed of data fitting, the local section tangent plane normal angle method was introduced to filter redundant points and retain the necessary data, and then the control points were adopted to fit the leaf surface based on Non-Uniform Rational B-Splines (NURBS) fitting algorithm. At the same time, the trunk was fitted based on NURBS according to the control points of the trunk, and the other branches were fitted using iterative method. Finally, the three-dimensional visualization of poplar seedlings was realized. A large number of experiments were carried out, including the normal growth poplar seedlings and the water shortages poplar seedlings. The results demonstrated that the poplar seedlings visualization method proposed in this paper can quickly and accurately reflect the growth states of the poplar seedlings, especially for water-shortage detection.

“…Previous approaches for simulating the dynamic system of trees can be roughly categorized in full simulation approaches, based on a computationally expensive integration of the equations of motion ([AK06,ZST*06,SF92,ZST*06, SO99]) and heuristic approaches ([SFT*03, WS05, Zio07, Sou07]) which do not consider the physical properties of trees. There are also hybrid techniques [GCF01,WVHR06].…”

This paper presents a new method to animate the interaction of a tree with wind both realistically and in real time. The main idea is to combine statistical observations with physical properties in two major parts of tree animation. First, the interaction of a single branch with the forces applied to it is approximated by a novel efficient two step nonlinear deformation method, allowing arbitrary continuous deformations and circumventing the need to segment a branch to model its deformation behavior. Second, the interaction of wind with the dynamic system representing a tree is statistically modeled. By precomputing the response function of branches to turbulent wind in frequency space, the motion of a branch can be synthesized efficiently by sampling a 2D motion texture. Using a hierarchical form of vertex displacement, both methods can be combined in a single vertex shader, fully leveraging the power of modern GPUs to realistically animate thousands of branches and ten thousands of leaves at practically no cost.

“…In the case of complex patterns, as long as a few IFS parameters are available, an iterated function system for pattern realization is subsequently determined. Therefore, IFS has been widely applied to many aspects of science simulation and creative design , especially plant simulation [4][5], printing on fabric [6], leather carving, biological modelling [7], etc.…”

Aiming at virtual applications, a prototype of affine transformation for designing patterns is proposed in this paper. Due to the capability of generating fractal geometry with self-similar and micro-fine structure by simple affine transformation, the iterative function system (IFS) is utilized to model the prototype, which is comprised of prototype the affine transform, computing the parameters of IFS ,designing and implementing iterative algorithms, and generating basic fractal sets as well. Simulation experiments has shown the validity of the proposed method.
