Member Function Documentation

bind()

template<class It >

void gl::frame_buf_t::bind ( It it_begin, It it_end )

inline

Bind textures to this object's framebuffers as color attachments.

Parameters

it_begin	First texture object to attach.
it_end	One-past-the-end iterator for texture objects to attach.

copy()

void gl::frame_buf_t::copy	(	int	id,
		int	texture,
		int	offset_x,
		int	offset_y,
		int	width,
		int	height )

Copies a part of the framebuffer to texture

Parameters

id	Framebuffer index to copy from.
texture	Destination texture receiving the copied pixels.
offset_x	Source X offset in pixels.
offset_y	Source Y offset in pixels.
width	Frame or display width in pixels.
height	Frame or display height in pixels.

make()

frame_buf_t gl::frame_buf_t::make ( std::size_t count )

static

Allocate the underlying object and wrap it in the owning handle.

Parameters

count

Number of objects or handles to create.

Returns

Created backend object, or null when creation fails.

operator=()

frame_buf_t & gl::frame_buf_t::operator= ( frame_buf_t && )

default

Assign state from another instance while preserving ownership semantics.

Returns

Reference or value produced by the operator.
