Detailed Description

GeometryBuffer that uses vertex arrays.

This is used on hardware that does not support VBOs (vertex buffer objects).

Member Function Documentation

void KGLLib::GeometryBufferVertexArray::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

Implements KGLLib::GeometryBuffer.

Reimplemented in KGLLib::GeometryBufferVBO.

void KGLLib::GeometryBufferVertexArray::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).

Implements KGLLib::GeometryBuffer.

Reimplemented in KGLLib::GeometryBufferVBO.

bool KGLLib::GeometryBufferVertexArray::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::GeometryBuffer.

Reimplemented in KGLLib::GeometryBufferVBO.

void KGLLib::GeometryBufferVertexArray::render	(	int	vertices,
		int	offset
	)		[virtual]

Renders a subset of non-indexed buffer data. The buffer must be bound (by calling the bind() method) before it can be used.

Parameters:

indices	number of vertices to use.
offset	array index of the first vertex to use.

render(), renderIndexed(), bind(), unbind()

Implements KGLLib::GeometryBuffer.

void KGLLib::GeometryBufferVertexArray::renderIndexed	(	int	indices,
		int	offset
	)		[virtual]

Renders a subset of indexed buffer data. The buffer must be bound (by calling the bind() method) before it can be used.

Parameters:

indices	number of indices to use.
offset	array index of the first index to use.

render(), render(int, int), bind(), unbind()

Implements KGLLib::GeometryBuffer.

bool KGLLib::GeometryBufferVertexArray::unbind

(

)

[virtual]

Unbinds the buffer.

bind()

Reimplemented from KGLLib::GeometryBuffer.
