set() [1/7]

void QtAV::Uniform::set	(	const float &	v,
		int	count = 0
	)

set Set uniform value in host memory.

This will mark dirty if value is changed

Parameters

v	the value
count	number of element T to set. 0: depending on type and array size, the number is arrySize()*tupleSize(); TODO: Sampler

set() [2/7]

void QtAV::Uniform::set	(	const unsigned &	v,
		int	count = 0
	)

set() [3/7]

void QtAV::Uniform::set	(	const int &	v,
		int	count = 0
	)

set() [4/7]

		int	count = 0
	)

set() [7/7]

void QtAV::Uniform::set

(

const QVariant &

v

)

set

Parameters

v	the type T is limited to OpenGL basic types float, int, unsigned(ES3.0) and QVector<T> TODO: Qt types

setGL()

bool QtAV::Uniform::setGL

(

)

setGL Call glUniformXXX to update uniform values that set by set(const T&, int) and mark dirty false.

Currently only use OpenGL ES2 supported functions, i.e. uint, double types are not supported.

Returns

false if location is invalid, or if uniform type is not supported by QOpenGLFunctions TODO: Sampler

setType()

Uniform& QtAV::Uniform::setType	(	Type	tp,
		int	count = 1
	)

setType

Parameters

count

array size, or 1 if not array

tupleSize()

int QtAV::Uniform::tupleSize ( ) const

inline

tupleSize 2, 3, 4 for vec2, vec3 and vec4; 2^2, 3^2 and 4^2 for mat2, mat3 and mat4

type()

Type QtAV::Uniform::type ( ) const

inline

value()

template<typename T >

QVector<T> QtAV::Uniform::value ( ) const

inline

Return an array of given type.

the type T must match type(), for example T is float for Float, VecN, MatN and array of them
