Detailed Description

EGL image buffer with plane descriptors and imported GL textures.

Member Function Documentation

block()

const char * gl::buffer_t::block

(

)

const

Query a uniform block index from an OpenGL program.

Returns

Uniform block name associated with the buffer.

handle()

GLuint gl::buffer_t::handle

(

)

const

Return the native handle owned by the wrapper.

Returns

OpenGL buffer object name.

make()

buffer_t gl::buffer_t::make ( util::buffer_t< GLint > && offsets, const char * block, const std::string_view & data )

static

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

Parameters

offsets	Byte offsets for each uniform member in the block.
block	Uniform block name used for diagnostics and updates.
data	Initial bytes copied into the uniform buffer.

Returns

Created backend object, or null when creation fails.

update() [1/2]

void gl::buffer_t::update	(	const std::string_view &	view,
		std::size_t	offset = 0 )

Update one uniform member in the block buffer.

Parameters

view	Raw bytes to copy into the uniform block.
offset	Uniform-member index whose offset is used as the destination.

update() [2/2]

void gl::buffer_t::update	(	std::string_view *	members,
		std::size_t	count,
		std::size_t	offset = 0 )

Update multiple uniform members in the block buffer.

Parameters

members	Uniform members to query within the block.
count	Number of members in the array.
offset	First uniform-member index to update.
