Allocate()

void qx::buffer_base::Allocate ( GLsizeiptr  nSize, const void *  pData = nullptr, GLenum  eUsage = GL_DYNAMIC_DRAW  )

inlinevirtual

Allocate memory for the buffer.

Parameters

nSize	- data size
pData	- data pointer
eUsage	- the expected usage pattern of the data store

Definition at line 52 of file buffer_base.inl.

protectedpure virtual

Get buffer type barrier bit.

Return values

-	buffer type barrier bit

GetBufferType()

virtual GLenum qx::buffer_base::GetBufferType ( ) const

protectedpure virtual

Get buffer type.

Return values

-	buffer type

Update()

void qx::buffer_base::Update ( const void *  pData, GLsizeiptr  nSize, GLintptr  nOffset = 0  )

inlinevirtual

Update buffer.

Parameters

pData	- data pointer
nSize	- data size
nOffset	- offset from the buffer beginning
