Shadow Explorer

Intel Corporation


Features / Description

Shadow Explorer is a sample application, with source code, that allows developers to work with several shadowing techniques, examine the performance versus quality tradeoffs of each one, and discover which is best suited for their game. In this first version of Shadow Explorer, we include four algorithms for evaluation: simple shadow maps, percentage closer shadow maps, variance shadow maps and exponential variance shadow maps. Each method is optimized for performance and exposes several variables, which allow the developer to further refine the technique in real time. Additionally, two scenes are provided to enable the developer to explore the strengths of each technique on different types of geometry.

The Shadow Explorer configured to show Exponential Variance Shadow Maps with 5 cascades. Visualizing the shadow map cascades within Shadow Explorer. The light space and the cascades can be visualized concurrently as the user changes multiple shadow techniques and inputs in real time.

Intel's compilers may or may not optimize to the same degree for non-Intel microprocessors for optimizations that are not unique to Intel microprocessors. These optimizations include SSE2, SSE3, and SSSE3 instruction sets and other optimizations. Intel does not guarantee the availability, functionality, or effectiveness of any optimization on microprocessors not manufactured by Intel. Microprocessor-dependent optimizations in this product are intended for use with Intel microprocessors. Certain optimizations not specific to Intel microarchitecture are reserved for Intel microprocessors. Please refer to the applicable product User and Reference Guides for more information regarding the specific instruction sets covered by this notice.
