Direct3D 12 predication and queries sample
This sample demonstrates the use of binary occlusion queries and predication in Direct3D 12. The sample renders two quads; one of them animates and periodically occludes the other. For each rendered frame, a binary occlusion query is executed and the SetPredication API is used to conditionally draw the potentially occluded quad. A transparency effect is used to illustrate when the query determines that the quad is fully occluded.
Optional features
This sample has been updated to build against the Windows 10 Anniversary Update SDK. In this SDK a new revision of Root Signatures is available for Direct3D 12 apps to use. Root Signature 1.1 allows for apps to declare when descriptors in a descriptor heap won't change or the data descriptors point to won't change. This allows the option for drivers to make optimizations that might be possible knowing that something (like a descriptor or the memory it points to) is static for some period of time.
