Destructor

Member Function Documentation

void AllocateBuffer ( const unsigned int  size )

protected

Allocates the buffer data, copying the existing data

Parameters

size	The new size in bytes to allocate

void Bake

(

IGlsStateManager *

stateManager

)

Download the index buffer data to Open GL

Precondition

(_vboHandle != 0) && (_size > 0)

Parameters

stateManager

The OpenGL state to download the index buffer to

void Bind

(

IGlsStateManager *

stateManager

)

Bind the index buffer, e.g. make it current

Precondition

(_vboHandle != 0) && (_size > 0)

Parameters

stateManager

The OpenGL state to bind the buffer on

void DeallocateBuffer ( )

protected

Deallocates the buffer data

unsigned int GetSize ( ) const

inline

Returns

Returns the size of the index buffer

void SetIndex	(	const unsigned int	index,
		const unsigned short	value
	)

Sets one index

Precondition

index < _size

Parameters

index	The index of the index to set
val	The index data

void SetIndices

(

const unsigned short

indexData[]

)

Populates the the index buffer

Precondition

_size > 0

Parameters

indexData

The indices to set. The array length is assumed to be equal to GetSize()

void SetSize

(

const unsigned int

size

)

Sets the size of the index buffer

Parameters

size	New index buffer count

Member Data Documentation

unsigned short* _indexData

protected

The memory for storing the indices

unsigned int _size

protected
