Expand description
In an effort to make Vulkan synchronization more accessible, this library provides a simplification of core synchronization mechanisms such as pipeline barriers and events.
Rather than the complex maze of enums and bit flags in Vulkan - many combinations of which are invalid or nonsensical - this library collapses this to a much shorter list of ~40 distinct usage types, and a couple of options for handling image layouts.
Additionally, these usage types provide an easier mapping to other graphics APIs like DirectX 12.
Use of other synchronization mechanisms such as semaphores, fences and render passes are not addressed in this library at present.
Modules§
Structs§
- Buffer
Barrier - Buffer barriers should only be used when a queue family ownership transfer is required - prefer global barriers at all other times.
- Global
Barrier - Global barriers define a set of accesses on multiple resources at once.
If a buffer or image doesn’t require a queue ownership transfer, or an image
doesn’t require a layout transition (e.g. you’re using one of the
ImageLayout::General*layouts) then a global barrier should be preferred. - Image
Barrier - Image barriers should only be used when a queue family ownership transfer or an image layout transition is required - prefer global barriers at all other times.
Enums§
- Access
Type - Defines all potential resource usages
- Image
Layout - Defines a handful of layout options for images.
Rather than a list of all possible image layouts, this reduced list is
correlated with the access types to map to the correct Vulkan layouts.
Optimalis usually preferred.
Functions§
- get_
buffer_ memory_ barrier - Mapping function that translates a buffer barrier into a set of source and destination pipeline stages, and a buffer memory barrier, that can be used with Vulkan synchronization methods.
- get_
image_ memory_ barrier - Mapping function that translates an image barrier into a set of source and destination pipeline stages, and an image memory barrier, that can be used with Vulkan synchronization methods.
- get_
memory_ barrier - Mapping function that translates a global barrier into a set of source and destination pipeline stages, and a memory barrier, that can be used with Vulkan synchronization methods.
