		const long &	length
	)

		const long &	length
	)

VRamList() [3/7]

	)

VRamList() [5/7]

JGL::VRamList::VRamList	(	const Vector4 *	data,

	)

~VRamList()

JGL::VRamList::~VRamList

(

)

VRamList() [6/7]

JGL::VRamList::VRamList

(

const VRamList &

rhs

)

Copying around the VBO data to a new VBO like this is slow.

Pass to function by const reference or pointer always.

Here is the call graph for this function:

VRamList() [7/7]

JGL::VRamList::VRamList ( )

default

Member Function Documentation

GetDataF()

std::vector< GLfloat > JGL::VRamList::GetDataF

(

)

const

Get VBO data back from the GPU.

This is bad because the CPU is going to wait for the transfer to finish. Has limited use other than testing.

Here is the caller graph for this function:

GetDataUI()

std::vector< GLuint > JGL::VRamList::GetDataUI

(

)

const

Here is the caller graph for this function:

GetHandle()

GLuint JGL::VRamList::GetHandle

(

)

const

GetLength()

long JGL::VRamList::GetLength

(

)

const

Returns the number of elements in the list.

GetSize()

size_t JGL::VRamList::GetSize

(

)

const

Returns the size of the data in bytes.

IsFloatArray()

bool JGL::VRamList::IsFloatArray

(

)

const

SetData() [1/6]

void JGL::VRamList::SetData	(	const GLfloat *	data,
		const long &	length
	)

Replace the data of an existing VBO in it's entirety.

Must be same type. "length" refers to the number of elements in data. Not the number of bytes.

SetData() [2/6]

void JGL::VRamList::SetData	(	const GLuint *	data,
		const long &	length
	)

SetData() [3/6]

void JGL::VRamList::SetData	(	const Vector2 *	data,
		const long &	length
	)

SetData() [4/6]

void JGL::VRamList::SetData	(	const Vector2i *	data,
		const long &	length
	)

SetData() [5/6]

void JGL::VRamList::SetData	(	const Vector3 *	data,
		const long &	length
	)

SetData() [6/6]

void JGL::VRamList::SetData	(	const Vector4 *	data,
		const long &	length
	)

UpdateData() [1/6]

void JGL::VRamList::UpdateData	(	const GLfloat *	data,
		const long &	offset,
		const long &	length
	)

Update only a portion of the data in a VBO.

Must be same type. "length" refers to the number of elements in data. Not the number of bytes. "offset" refers the number of Typename T into the buffer the data you want to change is. For ex, offset 0 and length of 1 overwrites the first value. Offset 1 the second etc

UpdateData() [2/6]

void JGL::VRamList::UpdateData	(	const GLuint *	data,
		const long &	offset,
		const long &	length
	)

UpdateData() [3/6]

void JGL::VRamList::UpdateData	(	const Vector2 *	data,
		const long &	offset,
		const long &	length
	)

UpdateData() [4/6]

void JGL::VRamList::UpdateData	(	const Vector2i *	data,
		const long &	offset,
		const long &	length
	)

UpdateData() [5/6]

void JGL::VRamList::UpdateData	(	const Vector3 *	data,
		const long &	offset,
		const long &	length
	)

UpdateData() [6/6]

void JGL::VRamList::UpdateData	(	const Vector4 *	data,
		const long &	offset,
		const long &	length
	)
