score::gfx::BufferCopyRegion Struct Reference

Region-based GPU buffer copy for strided / gather patterns. More...

Detailed Description

Region-based GPU buffer copy for strided / gather patterns.

One src buffer → one dst buffer, with count distinct {srcOffset, dstOffset, size} regions. Emits ONE pre-barrier and ONE post-barrier for the whole batch on backends that need them (Vulkan), then issues the minimum native work:

• Vulkan : single vkCmdCopyBuffer call with count regions
• OpenGL : N glCopyBufferSubData (bindings reused)
• D3D12 : N CopyBufferRegion (no per-call barriers needed)
• D3D11 : N CopySubresourceRegion
• Metal : N copyFromBuffer within one MTLBlitCommandEncoder

Replaces what would otherwise be N copyBuffer() calls (each with its own barrier pair) for strided source layouts — the std430-vec3-padded-to-vec4 case in particular. Must be called inside beginExternal()/endExternal() like copyBuffer().
