Detailed Description

Manages an OpenGL shader program.

Constructor & Destructor Documentation

OpenGLShaderProgram::OpenGLShaderProgram ( const OpenGLContext & context )

noexcept

OpenGLShaderProgram::~OpenGLShaderProgram ( )

noexcept

static double OpenGLShaderProgram::getLanguageVersion ( )

static

Returns the version of GLSL that the current context supports.

E.g.

if (OpenGLShaderProgram::getLanguageVersion() > 1.199)
{
    // ..do something that requires GLSL 1.2 or above..
}

bool OpenGLShaderProgram::addShader	(	const char *const	shaderSourceCode,
		GLenum	shaderType
	)

Compiles and adds a shader to this program.

After adding all your shaders, remember to call link() to link them into a usable program.

If your app is built in debug mode, this method will assert if the program fails to compile correctly.

The shaderType parameter could be GL_VERTEX_SHADER, GL_FRAGMENT_SHADER, etc.

Returns: true if the shader compiled successfully. If not, you can call getLastError() to find out what happened.

bool OpenGLShaderProgram::link ( )

noexcept

Links all the compiled shaders into a usable program.

If your app is built in debug mode, this method will assert if the program fails to link correctly.

Returns: true if the program linked successfully. If not, you can call getLastError() to find out what happened.

const String& OpenGLShaderProgram::getLastError ( ) const

noexcept

Get the output for the last shader compilation or link that failed.

void OpenGLShaderProgram::use ( ) const

noexcept

Selects this program into the current context.

GLuint OpenGLShaderProgram::programID

The ID number of the compiled program.
