Member Function Documentation

CompileNewShaderFromFile()

static Shader * VAPoR::ShaderManager::CompileNewShaderFromFile ( const std::string &  path, const std::vector< std::string > &  defines = {}  )

static

Parameters

[in]

path

to GLSL source code file

Return values

Shader*	is returned on success
nullptr	is returned on failure

GetShader()

ShaderProgram * VAPoR::ShaderManager::GetShader

(

const std::string &

name

)

GetShaderDependencies()

static std::vector< std::string > VAPoR::ShaderManager::GetShaderDependencies ( const std::string &  path )

static

GetShaderTypeFromPath()

static unsigned int VAPoR::ShaderManager::GetShaderTypeFromPath ( const std::string &  path )

static

Returns an OpenGL shader type enum based on the file extension. Valid extensions are .vert, .frag, and .geom

Parameters

[in]

path

to GLSL source code file

GetSmartShader()

SmartShaderProgram VAPoR::ShaderManager::GetSmartShader

(

const std::string &

name

)

LoadResourceByKey()

int VAPoR::ShaderManager::LoadResourceByKey ( const std::string &  key )

virtual

Implements VAPoR::IResourceManager< std::string, ShaderProgram >.

PreProcessShader()

static std::string VAPoR::ShaderManager::PreProcessShader ( const std::string &  path, const std::vector< std::string > &  defines = {}  )

static

Implements the following preprocessor directives:

• #pragma auto_version This sets the GLSL version to the highest available
• #include FileName.glsl c-style include without quotes. Path is relative to shader base path This will also update line numbers with the #line directive
• #define X Each item in the defines list is added to the GLSL code after the #version directive

Parameters

[in]	path	to GLSL source code file
[in]	defines	list of definitions to be added to source
