D3DReflect

D3DReflect is a command-line utility designed for inspecting and analyzing Direct3D shader bytecode. It allows developers to examine the internal structure of compiled shader programs, providing insights into their operations and resource usage. The tool can decompile shader bytecode into a more human-readable format, often High-Level Shading Language (HLSL) or a similar intermediate representation.

The primary function of D3DReflect is to aid in debugging and optimization of graphics shaders. By viewing the decompiled code, developers can identify potential performance bottlenecks, understand how variables are used, and verify that the shader is behaving as intended. It supports various shader models, making it a versatile tool for different DirectX versions.

Key features of D3DReflect include the ability to list shader inputs and outputs, exposed constants, texture samplers, and other shader-related metadata. It can also export shader bytecode in different formats. The tool is particularly useful when source code for shaders is unavailable or when debugging issues that manifest only in the compiled form. It is often integrated into development workflows for game development and other graphics-intensive applications.
