Shadow image is an image-based shadow generation method, which has low dependence on the complexity of scene space, and its complexity only depends on the number of light sources and the resolution of shadow image. Shadow effect is often used in tattoos. Let’s take a look at shadow tattoos with me today.
Shadow plays an important role in realistic scene rendering. It can not only reflect the occlusion relationship between objects in space, but also reflect the geometric information of occluded objects and receiving surface. The real-time rendering of shadow also greatly increases the reality of scene rendering.
