 # Sampler Feedback Streaming
 
-This repository contains a demo of `DirectX12 Sampler Feedback Streaming`, a technique using DirectX12 Sampler Feedback to guide loading of tiles of a reserved resource on-demand per-frame. This allows scenes containing 100s of GBs of resources to be drawn using much less physical memory. The scene below uses just ~200MB of a 1GB heap, despite over 350GB of total texture resources.

 There is also a batch file "nvidia.bat". For some hardware, it was observed that the performance of [UpdateTileMappings](https://docs.microsoft.com/en-us/windows/win32/api/d3d12/nf-d3d12-id3d12commandqueue-updatetilemappings) impacted overall throughput *unless* the heap size was 32MB. One workaround is to create many 32MB heaps and distribute the resources across them.

+## Creating Your Own Textures
+
+The executable `DdsToXet.exe` converts BCn DDS textures to the custom XET format. Only BC1 and BC7 textures have been tested. Usage:
+
+    c:> ddstoxet.xet -in myfile.dds -out myfile.xet
+
+The batch file `convert.bat` will read all the DDS files in one directory and write XET files to a second directory. The output directory must exist.

+## TileUpdateManager: a library for streaming textures
 
 Within the source, there is a *TileUpdateManager* library that aspires to be stand-alone. The central object, *TileUpdateManager*, allows for the creation of streaming textures and heaps to contain them. These objects handle all the feedback resource creation, readback, processing, and file/IO.
