Member Function Documentation

addShaderProgram()

void sgct::ShaderManager::addShaderProgram	(	std::string	name,
		std::string_view	vertexSrc,
		std::string_view	fragmentSrc )

Adds shader programs to the manager.

The shaders will be compiled and linked to the program. The name of the shader needs to be unique or it won't be added and an exception is thrown. Both vertex shader and fragment shader source need to be provided, either as a link to a shader source code file or as shader source code.

Parameters

name	Unique name of the shader
vertexSrc	The vertex shader source code
fragmentSrc	The fragment shader source code

Exceptions

std::runtime_error

If there was an error creating the shader program

destroy()

void sgct::ShaderManager::destroy ( )

static

instance()

ShaderManager & sgct::ShaderManager::instance ( )

static

operator=() [1/2]

ShaderManager & sgct::ShaderManager::operator= ( const ShaderManager & )

delete

operator=() [2/2]

ShaderManager & sgct::ShaderManager::operator= ( ShaderManager && )

delete

removeShaderProgram()

bool sgct::ShaderManager::removeShaderProgram

(

std::string_view

name

)

Removes a shader program from the manager.

All resources allocated for the program will be deallocated and removed.

Parameters

name	Name of the shader program to remove

Returns

true if the shader program was removed correctly

shaderProgram()

const ShaderProgram & sgct::ShaderManager::shaderProgram

(

std::string_view

name

)

const

Get the specified shader program from the shader manager.

Parameters

name	Name of the shader program

Returns

The specified shader program

Exceptions

std::runtime_error

If the shader program with the name was not found

shaderProgramExists()

bool sgct::ShaderManager::shaderProgramExists

(

std::string_view

name

)

const

Check if a shader program exists in the manager.

Parameters

name	Name of the shader program
