VR and AR contents provide a rich user experience [1]. Realistic content with human computer interaction and immersion provides an improved user experience, but there is a limit to producing all elements realistically. In this study, we propose a method to advance the rendering of immersive content using background color information [2]. First, the elements necessary for Kelvin temperature rendering are derived from the color and background as context elements, and the rendering effect has been realized in the soap bubble. For soap bubbles Kelvin temperature rendering, the average color of the background is extracted and the color with the highest similarity is applied by comparing the main color and Kelvin temperature.

In this paper, we propose a method to generate and optimize the height map that is suitable to render a soap bubble. The height map represents the flow speed of soap bubbles. To this end, we have analyzed the flow of the soap bubble surface through experiment, derived the moving speed value for each section. Some image filters have been used for optimization that reflects the parameters of the derived height map. In addition, in order to verify the results of the study, actual data measuring the surface flow speed of soap bubbles, the speed of the initial height map, and the optimized height map speed have been compared and tested. Through this study, we reach the issue that it is possible to express the variable flow speed of soap bubbles with the optimized height map, and it will help to express various fluids.

컴퓨터의 하드웨어와 컴퓨터 그래픽스 기술이 발전하면서 비눗방울 생성에 대한 연구가 수행되어 왔다. 그러나 실제 물리적인 수치를 이용하여 가상현실 콘텐츠에서 사용가능한 비눗방울 재현에 관한 연구는 매우 드물다. 비눗방울은 어떤 도구를 사용하는지, 어떤 세기로 바람을 부는지, 주변 환경의 조건은 어떤지에 따라 다양한 모형과 색상으로 표현 된다. 본 논문에서는 가상 비눗방울 생성을 재현하기 위해 필요한 물리기반 파라미터를 제안하였다. 이를 위해 비눗방울 생성 도구와 바람을 부는 지속시간에 따른 비눗방울의 모양과 렌더링에 필요한 파라미터를 도출하고 실험하였다.
