virtual bool makVrv::DtGlShader::isValid ( ) const

virtual

a valid shader is one that is compiled without error and is ready to use in an OpenGL program

virtual unsigned int makVrv::DtGlShader::id ( ) const

virtual

the OpenGL ID of the internal OpenGL shader

static std::string makVrv::DtGlShader::loadShaderSource ( const std::string &  strFileName )

static

static API functions

Loads shader source code from a file.

static void makVrv::DtGlShader::saveShaderSource ( const std::string &  strFileName, const std::string &  strSource  )

static

Saves shader source code to a file.

static std::string makVrv::DtGlShader::fixVersionDirective ( const std::string &  shaderString )

static

Moves the #version directive to the top of the shader string to prevent shader compilation errors.

static void makVrv::DtGlShader::deleteShaders ( const std::vector< unsigned int > &  shaderVector )

static

Loop over the OpenGL shader ids in the shaderVector and deletes them from OpenGL.

static bool makVrv::DtGlShader::compileShader ( const std::string &  shader_name, const std::string &  source, DtGlShaderType  shaderType, unsigned int &  shaderID  )

static

Compiles a shader of type shaderType using source.

shaderID is the new shader id Returns True is the compile succeeded
