Project Components

The GFXReconstruct project provides tools for the capture and replay of graphics API calls, allowing the graphics commands executed by an application to be recorded to a file that may later be replayed to reconstruct the graphics-specific behavior of the captured application. The replay code has been organized with a framework design to make it easy to create additional tools for processing capture files.

The GFXReconstruct components currently provided with this repository are:

• The VK_LAYER_LUNARG_gfxreconstruct Vulkan layer for capturing Vulkan application commands.
• The D3D12 capture libraries for capturing D3D12 application commands.
• The gfxrecon-replay tool to replay GFXReconstruct capture files.
• The gfxrecon-info tool to print information describing GFXReconstruct capture files.
• The gfxrecon-compress tool to compress/decompress GFXReconstruct capture files.
  • NOTE: The gfxrecon-compress tool requires LZ4, Zstandard, and/or zlib, which are currently optional build dependencies.
• The gfxrecon-extract tool to extract SPIR-V binaries from GFXReconstruct capture files.
• The gfxrecon-convert tool to convert GFXReconstruct capture files to a JSON Lines listing of API calls. (experimental for D3D12 captures)
• The gfxrecon-optimize tool to produce new capture files with improved replay performance.
