An Efficient Shadow Texture Algorithm with Shadow Maps |
||||
Real-time shadow algorithms with shadow textures or shadow maps are the most
popular, but they suffer from visual artifacts. This paper presents an effcient
anti-aliased shadow rendering algorithm by using both shadow textures and
shadow maps. We generate shadows using shadow mapping, and store them into an
UV texture atlas being mapped on a geometric object instead of the
frame-buffer. Then we map the shadow texture on the object as a decal texture.
This algorithm can use filtering such as mipmapping supported by graphics
hardware, which cannot be used for conventional shadow mapping. This also
allows us making anti-aliased shadows easy with real-time performance of
hundreds frames per second. Our algorithm can be easily implemented on
commodity graphics hardware and integrated in exist real-time applications such
as games.
