Detailed Description

GeometryBuffer that uses VBOs.

This is the fastest way of rendering but hardware support for VBOs (vertex buffer objects) is required.

Member Function Documentation

void KGLLib::GeometryBufferVBO::addData	(	void *	data,
		int	size,
		int	offset
	)		[protected, virtual]

Writes data to the internal buffer.

Parameters:

data	pointer to the data
size	size of the data in bytes
offset	offset of the internal buffer in bytes

Reimplemented from KGLLib::GeometryBufferVertexArray.

void KGLLib::GeometryBufferVBO::addIndices	(	unsigned int *	indices,
		int	count,
		int	offset = 0
	)		[virtual]

Sets the indices array to indices. The array must contain at least count entries (if it contains more, then the remaining ones will be unused).

Reimplemented from KGLLib::GeometryBufferVertexArray.

bool KGLLib::GeometryBufferVBO::bind

(

)

[virtual]

Binds the buffer. The buffer must be bound before you can use any of the render methods.

See also:

unbind()

Reimplemented from KGLLib::GeometryBufferVertexArray.

bool KGLLib::GeometryBufferVBO::unbind

(

)

[virtual]

Unbinds the buffer.

See also:

bind()

Reimplemented from KGLLib::GeometryBufferVertexArray.
