Info

Root Descriptors Stores a single descriptor directly as a root parameter – No need to burn through descriptor heap space – Most useful for a descriptor that changes ~ every draw Can only reference “raw data” – Only buffer resources (CBVs, SRVs/UAVs of buffers) – No type conversions (i.e. only float/uint/sint components) – i.e. it’s just a pointer to memory – No out of bounds checking!

Descriptor Tables Maps continuous range of descriptors to shader slots – Can mix SRVs, UAVs, and CBVs arbitrarily Multiple descriptor tables can point to disjoint ranges – Ex. Use separate parameters for different update frequencies – Per-scene, per-material, per-instance, per-draw, etc. – Similar to constant buffers, now also for the descriptors too Copyright © 2015, Intel Corporation.
