Detailed Description

A structure containing the individual parts of the code of a load-time preprocessed (by g3d, not the driver) shader.

This is combined with the macro argument and preamble string at compilation time in the following manner: versionString + g3dInsertString + expandForPragmas(preprocessedCode).

Member Data Documentation

◆ extensionsString

String G3D::Shader::PreprocessedShaderSource::extensionsString

Multiple lines containing "\#extension ..." definitions.

Inserted at the beginning of the final code submitted to the driver, right after the version line.

◆ filename

String G3D::Shader::PreprocessedShaderSource::filename

The filename of the file where the code was originally loaded from.

Note that this does not somehow account for #include pragmas.

◆ g3dInsertString

String G3D::Shader::PreprocessedShaderSource::g3dInsertString

The #defines and uniform args added by G3D.

Does not include user-defined macro arguments or preamble

◆ preprocessedCode

String G3D::Shader::PreprocessedShaderSource::preprocessedCode

The original code, with #includes evaluated, and the version line (if existant) replaced with an empty line.

This is before the actual driver preprocessing and #for pragma expansion, so #defines, #ifs, and #fors have not yet been evaluated

◆ versionString

String G3D::Shader::PreprocessedShaderSource::versionString

A line of the form "\#version XXX" where XXX is a three digit number denoting the GLSL version for the graphics driver to use.

Inserted at the beginning of the final code submitted to the driver.
