Reconstructing 3D Tree Models Using Motion Capture and Particle Flow

Figure 7

A simple particle flow results in crown branching structure.

(a) Flow direction depends on root attractor and nearest trunk point positions

(b) Root attractor point 𝑆_𝑟 and nearest trunk point 𝑆_𝑡

(c) Particle flow ends when a particle merges with a neighbor or with the trunk
