چکیده
Real-Time (60fps @ 1920x1200) Shadows Produced Using Our Algorithm Variance shadow maps (VSMs) provide an e cient way to produce highquality, ltered shadows in real-time, but su er from light bleeding artifacts. Layered variance shadow maps automatically partition the depth range into multiple layers, which alleviates or eliminates light bleeding artifacts. Compared to VSMs, LVSMs: • Reduce or eliminate light bleeding artifacts • Do not require high-precision (32-bit float) texture filtering • Can still be generated in one pass and need only one texture sample per pixel • Allow shadow quality to be easily scaled up at the cost of more storage Variance Shadow Map

Smooth shadow boundaries with exponentially warped Gaussian filtering
Shadow mapping is widely used in computer graphics for efficiently rendering shadows in real-time applications. Shadow maps cannot be filtered as regular textures, thus their limited resolution can cause severe shadow map discretization artifacts in the rendered images. To solve this problem, several techniques have been proposed, including variance shadow maps (VSM) and exponential shadow maps...
متن کاملLayered Reflective Shadow Maps for Voxel-based Indirect Illumination
We introduce a novel voxel-based algorithm that interactively simulates both diffuse and glossy single-bounce indirect illumination. Our algorithm generates high quality images similar to the reference solution while using only a fraction of the memory of previous methods. The key idea in our work is to decouple occlusion data, stored in voxels, from lighting and geometric data, encoded in a ne...
متن کاملIsosurface Ambient Occlusion and Soft Shadows with Filterable Occlusion Maps
Volumetric data sets are often examined by displaying isosurfaces, surfaces where the data or function takes on a given value. We propose a new method for rendering isosurfaces at interactive rates while supporting dynamic ambient occlusion and/or soft shadows and requiring minimal pre-computation time. By approximating the occlusion in a region as the percentage of occluding voxels in that reg...
متن کاملRendering Soft Shadows using Multilayered Shadow Fins
Generating soft shadows in real-time is difficult. Exact methods (such as ray tracing, and multiple light source simulation) are too slow, while approximate methods often over-estimate the umbra regions. In this paper, we introduce a new algorithm based on the shadow map method to quickly and accurately render soft shadows produced by a light source. Our method builds inner and outer translucen...
متن کاملSubdivided Shadow Maps
Figure 1: Comparison between trapezoidal shadow maps (TSMs) and subdivided shadow maps. a) TSM with 1K×1K shadow map, b) TSM with 4K×4K shadow map, and c) 1K×1K subdivided shadow map. This configuration with a small angle between the light and view directions is difficult for prior methods. Even with the largest shadow map that can be allocated on current hardware, TSMs are not able to match th...
