DirectX11ShaderInfo

Description

sealed class Tinman.AddOns.DirectX11.Effects.DirectX11ShaderInfo

Derived from

DirectXShaderInfo
ICodeOutput

Full source code is included in the Tinman 3D SDK download.

Represents the shader metadata that the HLSL compiler writes into the Assembler Output / *.asm files.

The source code produced via ICodeOutput is minimal but parseable Assembler Output / *.asm file that contains the required shader metadata, see Reduce.

Direct​X11​Shader​Info

public constructor DirectX11ShaderInfo → (1)

assemblerOutput in : string

[not-null]
Source code of the Assembler Output / *.asm file, generated by the HLSL compiler.

Creates a new instance of DirectXShaderInfo.

This is the grammar for parsing the leading comment block of Assembler Output / *.asm files:
