Description

Contains a list of indices that describe which particular part of the nap::MeshInstance should be drawn. Every nap::MeshInstance contains at least one shape.

Member Function Documentation

addIndex()

void addIndex

(

uint32

index

)

Adds a single index to the index CPU buffer. Use setIndices to add an entire list of indices. Call either before init() or call update() to reflect the changes in the GPU buffer.

Parameters

index

Index to add.

addIndices()

void addIndices	(	uint32 *	indices,
		int	numIndices
	)

Adds a number of indices to the existing indices in the index CPU buffer. Use setIndices to replace the current indices with a new set of indices. Call either before init() or call update() to reflect the changes in the GPU buffer.

Parameters

indices	List of indices to update.
numIndices	Number of indices in the list.

clearIndices()

void clearIndices

(

)

Clears the list of indices. Call either before init() or call update() to reflect the changes in the GPU buffer.

getIndices() [1/2]

std::vector<uint32>& getIndices

(

)

Returns

The index list for this shape

getIndices() [2/2]

const std::vector<uint32>& getIndices

(

)

const

Returns

The index list for this shape

getNumIndices()

int getNumIndices

(

)

const

Returns

The number of indices in this shape

operator[]() [1/2]

uint32& operator[]

(

std::size_t

index

)

Array subscript overload.

Parameters

index

lookup index

Returns

value at the given index

operator[]() [2/2]

const uint32& operator[]

(

std::size_t

index

)

const

Const array subscript overload.

Parameters

index

lookup index

Returns

value at the given index

reserveIndices()

void reserveIndices

(

size_t

numIndices

)

Reserves CPU memory for index list. GPU memory is reserved after update() is called.

Parameters

numIndices

Amount of indices to reserve.

setIndices()

void setIndices	(	uint32 *	indices,
		int	numIndices
	)

Adds a list of indices to the index CPU buffer. Call either before init() or call update() to reflect the changes in the GPU buffer.

Parameters

indices	array of indices to add.
numIndices	size of the array.
