초록

Omni-directional high dynamic range images are used in image-based lighting or environment mapping. In game development environment high dynamic images can be used with shader assets. Recently various 360 VR camera systems are produced which can capture omni-directional images or video images without extra image stitching. In game development environment, shader assets or assets for shaders can be made along very time-consuming complex processes. In this paper, we proposed more simple and autonomous conversion system which can use directly in Unity.
