본 논문에서는 미리 모델링된 실객체에 대한 3차원 모델을 변형하면서 애니메이션을 정의하고, 실사 객체를 추적하면서 카메라 뷰 상의 실사 객체에 애니메이션을 적용하는 방법을 제안한다. 애니메이션 정의는 라플라시안 기반 메쉬 변형 방법으로 3차원 모델을 변형시키며 키프레임을 지정함으로써 이루어진다. 정의된 애니메이션은 실제 환경에서 추적된 실사 객체의 영상으로부터 모델에 텍스처를 입힌 뒤, 카메라 포즈를 이용하여 객체 위치에 객체 모델을 렌더링할 때 적용된다. 제안된 방법을 통해 사용자가 원하는 대로 실제 환경에 대한 카메라 뷰 상에서 실사 객체가 변형되는 모습을 용이하게 보여줄 수 있다.

In order to investigate characteristics of waves and currents varying in space in the Haeundae coast in winter, numerical simulations by using a 2-D spectral wave model(SWAN) and 2-DH hydrodynamic model(Delft3D) were carried out in this study. The results of numerical simulations were validated with the field data collected at several different locations in the study area in February, 2014. From the numerical simulations, it was found that waves and currents were significantly influenced in terms of direction and magnitude by bottom topography characterized by straggling rock crops covered with sea grasses. The coupling of SWAN and Delft3D models also revealed that alongshore currents directing from the east to the west were developed in the nearshore, due to the influence of larger waves with the main incident direction from the east.

Purpose: The purpose of this study was to compare the accommodative function of young adult in their 20s wearing monovision, modified monovision, and aspheric multifocal contact lenses at near task. Methods: Thirty young adults ($23.53{\pm}2.37years$) were fitted with monovision, modified monovision (the application of single vision contact lenses and center-near low addition aspheric multifocal contact lenses), and aspheric center-near multifocal contact lenses. After wearing these modalities during a week for adaption, and after watching visual display at computer for inducing accommodative pressure for 1 hour. The following assessments of accommodative function were made: contrast visual acuity (VA) at distance and near; accommodative response; near accommodative facility; and negative relative accommodation (NRA)/positive relative accommodation (PRA). All measurements were carried out binocularly. Results: In binocular distance VA with contrast of 10%, monovision was the worst among the four modalities (p=0.005). In accommodative response at 1 m (1.00 D), monovision was the lowest (p<0.05) and accommodative response at 40 cm (2.50 D) with monovision was lower than that of modified monovision and multifocal contact lens (p<0.05). We also found that there were no significant differences in accommodative facility and NRA/PRA among the four modalities. Conclusions: In young adult (20s), monovision with low add reduced the accommodative response at near task, however, modified monovision and multifocal lens with center-near type did not affect accommodative relaxation.
