Detailed Description

Shader compiler interface. Custom shader compilers need to derive from this class and implement the pure virtual interface functions. Instances are created via reflection, so each implementation must be properly reflected.

Member Function Documentation

Compile()

virtual xiiResult xiiGALShaderProgramCompiler::Compile ( xiiGALShaderProgramData & inout_data, xiiLogInterface * pLog )

pure virtual

Compiles the shader comprised of multiple stages defined in inout_data.

Parameters

inout_data	The state of the shader compiler. m_Resources and m_ByteCode should be written to on successful return code.
pLog	Logging interface to be used when outputting any errors.

Returns

Returns whether the shader was compiled successfully. On failure, errors should be written to pLog.

Implemented in xiiShaderCompilerDXIL, and xiiShaderCompilerSPIRV.

GetSupportedPlatforms()

virtual void xiiGALShaderProgramCompiler::GetSupportedPlatforms ( xiiHybridArray< xiiString, 4 > & out_platforms )

pure virtual

Returns the platforms that this shader compiler supports.

Parameters

out_platforms

Filled with the platforms this compiler supports.

Implemented in xiiShaderCompilerDXIL, and xiiShaderCompilerSPIRV.

ModifyShaderSource()

virtual xiiResult xiiGALShaderProgramCompiler::ModifyShaderSource ( xiiGALShaderProgramData & inout_data, xiiLogInterface * pLog )

pure virtual

Allows the shader compiler to modify the shader source before hashing and compiling. This allows it to implement custom features by injecting code before the compile process. Mostly used to define resource bindings that do not cause conflicts across shader stages.

Parameters

inout_data	The state of the shader compiler. Only m_sShaderSource should be modified by the implementation.
pLog	Logging interface to be used when outputting any errors.

Returns

Returns whether the shader could be modified. On failure, the shader won't be compiled.

Implemented in xiiShaderCompilerDXIL, and xiiShaderCompilerSPIRV.
