Shadow Volumes
Over the last 10 years, significant progress has been made in the field of computer graphics, especially in real-time rendering. Most noteworthy, the use of dedicated graphics accelerator hardware has found its way from the professional to the consumer market, and their ever increasing power has allowed for rendering almost photorealistic virtual environments while still maintaining interactive...
متن کاملPartitioned Shadow Volumes
Real-time shadows remain a challenging problem in computer graphics. In this context, shadow algorithms generally rely either on shadow mapping or shadow volumes. This paper rediscovers an old class of algorithms that build a binary space partition over the shadow volumes. For almost 20 years, such methods have received little attention as they have been considered lacking of both robustness an...
متن کاملShadow Volumes Revisited
We present a method to utilize the Shadow Volume Algorithm by Crow and Williams without using a stencil buffer. We show that the shadow mask can be generated in the alpha channel or even in the screen buffer, if a hardware-accelerated stencil buffer is not available. In comparison to the original stencil buffer method, a small speed up can be achieved, if the shadow mask is computed in the alph...
متن کاملShadow Volumes on Programmable Graphics Hardware
One of the best choices for fast, high quality shadows is the shadow volume algorithm. However, for real time applications the extraction of silhouette edges can significantly burden the CPU, especially with highly tessellated input geometry or when complex geometry shaders are applied. In this paper we show how this last, expensive part of the shadow volume method can be implemented on program...
متن کاملShadow Volumes in Unreal Engine 4
The presented bachelor thesis project explores the possibilities of implementing custom lighting techniques in a state-of-the-art game engine. Specifically, Unreal Engine 4 is analyzed for the feasibility of implementing shadow volumes in a shader-centric plugin. The thesis discusses the theoretical and practical background of Unreal Engine and of shadow volumes, and provides detailed informati...
