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.

As computer hardware and computer graphics technologies have developed in recent years, one can find research on the creation of bubbles. However, it is not easy to find soap bubbles that are modeled and rendered using actual physical parameters. The bubbles are expressed in a variety of models and colors depending on which tool is used, which strength is used, and the conditions of the surrounding environment. Therefore, in this paper, we present synthetic methods to create virtual soap bubbles based on physical parameters derived from some straws such as the bubbles' diameter over time and the number of bubbles when blowing. On the top of that, we will show a model of a soap bubble that can be usable in a virtual reality contents and optimized with rendering parameters.
