Hardware Accelerated Soft Shadows using Penumbra Quads
Shadow mapping is a commonly used technique for generating hard shadows in real time. However, existing shadow map based algorithms cannot render full soft shadows penumbras onto ...

Layered variance shadow maps
Shadow maps are commonly used in real-time rendering, but they cannot be filtered linearly like standard color, resulting in severe aliasing. Variance shadow maps resolve this pro...

Interpolation-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 propert...

Robust Soft Shadow Mapping with Backprojection and Depth Peeling
Abstract. Soft shadow mapping is an attractive solution to the problem of realtime soft shadows because it works with any kind of rasterizable geometry (in particular alpha-transpa...

Sample Based Visibility for Soft Shadows using Alias-free Shadow Maps
This paper introduces an accurate real-time soft shadow algorithm that uses sample based visibility. Initially, we present a GPU-based alias-free hard shadow map algorithm that ty...
