Description

template<typename ELEMENTTYPE>
class nap::VertexAttribute< ELEMENTTYPE >

Typed interface for vertex attributes. CPU data can be read by using getValues(). CPU data can be updated by using the various other functions. Make sure to call MeshInstance::update() after edits are performed. Notice that all known vertex attribute types have specializations for GetType and GetNumComponents.

addData() [1/2]

void addData

(

const ELEMENTTYPE &

element

)

Adds a single element to the end of the buffer. Data is copied.

Parameters

element

to add.

addData() [2/2]

void addData	(	const ELEMENTTYPE *	elements,
		int	numElements
	)

Adds data to the existing data in the buffer. Data is copied.

Parameters

elements	pointer to the elements to add.
numElements	number of elements in buffer to add.

clear()

void clear

(

)

Clears all data associated with this attribute

getCapacity()

virtual size_t getCapacity ( ) const

overridevirtual

Returns

The internally allocated memory size.

Implements BaseVertexAttribute.

getCount()

virtual int getCount ( ) const

overridevirtual

Returns

the number vertices in the buffer

Implements BaseVertexAttribute.

getData() [1/2]

std::vector<ELEMENTTYPE>& getData

(

)

Returns

Types interface toward the internal values. Use this function to read CPU data.

getData() [2/2]

const std::vector<ELEMENTTYPE>& getData

(

)

const

Returns

Types interface toward the internal values. Use this function to read CPU data.

getFormat()

NAPAPI VkFormat getFormat ( ) const

overridevirtual

Returns

the VK_FORMAT of this vertex attribute

Implements BaseVertexAttribute.

getRawData()

void * getRawData

overrideprotectedvirtual

Implementation for all typed buffer, returns data.

Implements BaseVertexAttribute.

operator[]() [1/2]

ELEMENTTYPE& operator[]

(

std::size_t

index

)

Array subscript overload

Parameters

index

Returns

the vertex attribute value at index

operator[]() [2/2]

const ELEMENTTYPE& operator[]

(

std::size_t

index

)

const

Const array subscript overload

Parameters

index

the index of the attribute value

Returns

the vertex attribute value at index

reserve()

virtual void reserve ( size_t  numElements )

overridevirtual

Reserves a certain amount of CPU memory to hold the given number of elements

Parameters

numElements

the number of elements to reserve memory for.

Implements BaseVertexAttribute.

resize()

void resize

(

size_t

numElements

)

Resizes the data container to hold the given number of elements.

Parameters

numElements

the new number of elements.

setData() [1/2]

void setData	(	const ELEMENTTYPE *	elements,
		int	numElements
	)

Sets the entire vertex attribute buffer.

Parameters

elements	pointer to the elements to copy.
numElements	amount of elements to copy.

setData() [2/2]

void setData

(

const std::vector< ELEMENTTYPE > &

values

)

Sets the internal values based on the contained type

Parameters

values

the values that will be copied over
