The modeling of plants is an active area of research in computer graphics and the geometrical modeling of veins is essential for obtaining plant images with a realistic appearance. The venation patterns determine the anisotropy of plant tissues, and affect the shadowing and masking of light incident on these tissues, hence the images. The current trend in the area of plant image generation is to aim for realism using biologically-based and predictable algorithms. Such algorithms do not depend on ad hoc parameters that have to be tuned whenever a new image is being generated. A number of plant image generation algorithms are now available in the literature that have achieved an impressive level of sophistication in many aspects, generating realistic looking images. One notable exception is the geometrical modeling of veins. This remains as an open problem in computer graphics. In this paper we review the state of art of the realistic simulation of plant venation systems from a geometric modeling perspective and propose a specified set of requirements for evaluating possible solutions for this problem.
Submultiplicativity, an analytic property generalizing the Strengthened Hanna Neumann Conjecture (SHNC) to complexes was proved in [2] assuming the deep-fall property. This in particular implied SHNC. The purpose of this note is to write the proof of the original SHNC and purely in terms of groups and graphs. We also give explicit examples showing that the upper bound in SHNC is sharp.
Background: When performing partial toe-transfer flaps with a short vascular pedicle, as the flap becomes smaller, the likelihood of securing veins in the flap decreases. The purpose of this study was to clarify how frequently the partial toe-transfer flap with a short pedicle (free vascularized half-big toenail flap) contains veins and elucidate how frequently we can secure the veins with an artery via the first web space approach alone, using the Genial Viewer (a near-infrared light transmission imaging device).
Methods: We observed the dorsal vein images of the bilateral big toes of 250 volunteers (male, n = 125; female, n = 125) using the device. We counted the total number of dorsal veins in the big toe, the veins that crossed the margin of the region equivalent to the half-big toenail flap, and the veins that branched off from the fibular side of the flap area. An unpaired Student’s t-test was used for the statistical analyses.
Results: All of the dorsal big toes contained veins. The mean number of the veins was 2.3 (range, 1–4). Branched-off veins were observed in the area equivalent to the half-big toenail flap in 496 (99.2%) of the big toes, and the mean number of veins was 1.9 (range, 0–4). In four cases, the region contained no veins (unilaterally). Branched-off veins were observed in the first web space in 440 (88.0%) of the big toes, and the mean number of veins was 0.9 (range, 0–2).
Conclusions: The present study indicated high consistency of the veins in partial toe-transfer flaps with a short vascular pedicle and the high possibility of harvesting a flap with only exposing the first web space. In addition, in most cases, the flap will include one or, at most, two veins in the first web space.
