Inherits: GpuSurfaceBarrier

Describes a barrier for a Texture.

SPtr<Texture> Object

Subresources (mips, array levels) of the textures to apply the barrier to.

ImageLayout SourceLayout

Source image layout.

If usage is set to undefined, layout is determined from the current usage of the texture object, otherwise it must be provided.

ImageLayout DestinationLayout

Destination image layout.

If set to Undefined, no layout transition will be performed.

GpuResourceUseFlags SourceUsage

Determines how was resource used before the barrier.

Barrier will only work for provided accesses. If undefined, source usage, access and layout is automatically deduced based on current buffer use.

GpuAccessFlags SourceAccess

Determines if the resource was read or written before the barrier.

GpuResourceUseFlags DestinationUsage

Determines how was resource will be used after the barrier.

Barrier will only work for provided accesses. Images will transition to a layout compatible for this usage - incompatible usages are not allowed.

GpuAccessFlags DestinationAccess

Determines if the resource will be read or written after the barrier.
