Detailed Description

Vulkan maps per pool, thus mapping the same pool twice is a common occurrence.

This class takes care of mapping pools just once while allowing BufferInterface to map subregions of it as if they were separate buffers.

Remarks

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.

Member Function Documentation

flush()

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

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

getDeviceMemory()

isCoherentMemory()

map()

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

Assumes mVboName is already bound to GL_COPY_WRITE_BUFFER!!!

unmap()

(

size_t

ticket

)

Unmaps given ticket (got from.

map). Assumes mVboName is already bound to GL_COPY_WRITE_BUFFER!!! The ticket becomes invalid after this.
