Detailed Description

Metal doesn't "map".

You can directly access the unsynchronized contents For performance we keep many buffers as one big buffer, but for compatibility reasons (with GL3/DX10 HW) we treat them as separate buffers.

: This class treats mapping in a GL-style. The most usefulness is that in OS X we need to inform what regions were modified (flush). On iOS it serves no real purpose and is just a pass through with some asserts for consistency checking.

Remarks: This is a very thin/lightweight wrapper around MTLBuffer, thus: Caller is responsible for flushing regions before unmapping. Caller is responsible for proper synchronization. No check is performed to see if two map calls overlap.

Constructor & Destructor Documentation

◆ MetalDynamicBuffer()

Ogre::MetalDynamicBuffer::MetalDynamicBuffer	(	id< MTLBuffer >	vboName,
		size_t	vboSize
	)

◆ ~MetalDynamicBuffer()

Ogre::MetalDynamicBuffer::~MetalDynamicBuffer ( )

Member Function Documentation

◆ flush()

void Ogre::MetalDynamicBuffer::flush	(	size_t	ticket,
		size_t	start,
		size_t	count
	)

Flushes the region of the given ticket. start is 0-based.

◆ getVboName()

id<MTLBuffer> Ogre::MetalDynamicBuffer::getVboName ( ) const

inline

◆ map()

void* RESTRICT_ALIAS_RETURN Ogre::MetalDynamicBuffer::map	(	size_t	start,
		size_t	count,
		size_t &	outTicket
	)

◆ unmap()

void Ogre::MetalDynamicBuffer::unmap ( size_t ticket )

Unmaps given ticket (got from.

See also: map). The ticket becomes invalid after this.
