Member Function Documentation

addShader()

void igor::iShaderProgram::addShader	(	const iaString &	filename,
		iShaderObjectType	type
	)

add shader object from file

Parameters

filename	file name to shader definition
type	the type of shader object.

If type is undefined we use the file ending to determine the type

addSource()

bool igor::iShaderProgram::addSource	(	const char *	source,
		iShaderObjectType	type,
		const iaString &	sourceName = ""
	)

add shader from buffer

Parameters

source	pointer to buffer with shader definition (zero terminated)
type	the type of shader object

Returns

true if sucessful

bind()

void igor::iShaderProgram::bind

(

)

activates shader program

compile()

void igor::iShaderProgram::compile

(

)

compiles shader programm with shader objects

create()

iShaderProgramPtr igor::iShaderProgram::create ( )

static

Returns

a newly created shader program

getShaderSources()

const std::vector< iShaderSource > & igor::iShaderProgram::getShaderSources

(

)

const

Returns

shader source files

it does not return sources added via addSource

hasUniformLocation()

bool igor::iShaderProgram::hasUniformLocation

(

const iaString &

uniform

)

Returns

true if shader has given uniform location

Parameters

uniform

the given uniform location

isValid()

bool igor::iShaderProgram::isValid

(

)

Returns

true: if ready to use

setFloat()

void igor::iShaderProgram::setFloat	(	const iaString &	uniform,
		float32	value
	)

sets float on given uniform

Parameters

uniform	the uniform name
value	the value to set

setFloat2()

void igor::iShaderProgram::setFloat2	(	const iaString &	uniform,
		const iaVector2f &	value
	)

value	the value to set

setFloat3()

void igor::iShaderProgram::setFloat3	(	const iaString &	uniform,
		const iaVector3f &	value
	)

sets 3 dimensional vector on given uniform

Parameters

uniform	the uniform name
value	the value to set

setFloat4()

void igor::iShaderProgram::setFloat4	(	const iaString &	uniform,
		const iaVector4f &	value
	)

Parameters

uniform	the uniform name
value	the value to set

setInt()

void igor::iShaderProgram::setInt	(	const iaString &	uniform,
		int	value
	)

sets integer on given uniform

Parameters

uniform	the uniform name
value	the value to set

setMatrix()

void igor::iShaderProgram::setMatrix	(	const iaString &	uniform,
		const iaMatrixf &	value
	)
