Soft Shadow Maps: Efficient Sampling of Light Source Visibility
Shadows, particularly soft shadows, play an important role in the visual perception of a scene by providing visual cues about the shape and position of objects. Several recent algorithms produce soft shadows at interactive rates, but they do not scale well with the number of polygons in the scene or only compute the outer penumbra. In this paper, we present a new algorithm for computing interac...
متن کاملRevectorization-Based Accurate Soft Shadow using Adaptive Area Light Source Sampling
Physically-based accurate soft shadows are typically computed by the evaluation of a visibility function over several point light sources which approximate an area light source. This visibility evaluation is computationally expensive for hundreds of light source samples, providing performance far from real-time. One solution to reduce the computational cost of the visibility evaluation is to ad...
متن کاملSoft Shadow Maps for Area Light by Area Approximation
Shadow mapping has been a popular way of generating shadows in real-time applications, but it is still incapable of generating realistic real time soft shadows for area light. There is an algorithm for generating soft shadows for linear light with few samples, but the algorithm is not suitable for area light. In this article, the author presents a modified method to the shadow mapping algorithm...
متن کاملInterpolation-Friendly Soft Shadow Maps
We present Penumbra Limit Maps, a technique for rendering soft shadows from a modified shadow map. The shadow representation used by our method has excellent interpolation properties, allowing the shadow boundary to be rendered with sub shadowmap-pixel accuracy, which partially mitigates the resolution problems common to shadow map methods. Unlike similar shadow map methods, our method includes...
متن کاملLight Space Perspective Shadow Maps
In this paper, we present a new shadow mapping technique that improves upon the quality of perspective and uniform shadow maps. Our technique uses a perspective transform specified in light space which allows treating all lights as directional lights and does not change the direction of the light sources. This gives all the benefits of the perspective mapping but avoids the problems inherent in...
