Detailed Description

Provides functionality to load GLSL source code from a file, compile it, link it and bind it to the context.

Constructor & Destructor Documentation

Shader::Shader

(

const std::string &

name)

Creates a shader with an associated name. Name will be displayed to link error message to it.

Member Function Documentation

bool Shader::attachShaderFile	(	int	type,
		const std::string &	path
	)

Attaches source code from a file to this shader. Shader type is one of GL_VERTEX_SHADER, GL_GEOMETRY_SHADER, GL_FRAGMENT_SHADER.

Parameters

path	file relative to the folder shaders/

bool Shader::attachShaderSource	(	int	type,
		const std::string &	source
	)

Attaches source code from a string to this shader. Shader type is one of GL_VERTEX_SHADER, GL_GEOMETRY_SHADER, GL_FRAGMENT_SHADER.

void Shader::bind

(

)

Binds the shader to the context.

bool Shader::compileShaders

(

)

Attempt to compile all source code attached to this object. Error messages are displayed at the standard output.

GLint Shader::getAttribLocation

(

const std::string &

name)

const

Returns the generic vertex attribute location name of this shader.

GLint Shader::getUniformLocation

(

const std::string &

name)

const

Returns the uniform location name of this shader.

bool Shader::link

(

const std::string &

out)

Links all compiled shaders to form a shader program. out is the only frag data location.

bool Shader::link	(	const std::string *	out,
		int	numAttachments
	)

Links all compiled shaders to form a shader program. out is a pointer to the first element in an array of frag data locations. numAttachments is the number of frag data locations.

void Shader::unbind

(

)

Unbinds the currently bound shader from the context.
