resolve_gpu_image()

template<GpuImageSource T>

std::shared_ptr< Core::VKImage > MayaFlux::Buffers::resolve_gpu_image

(

const T &

buffer

)

Resolve the GPU-resident image from any GpuImageSource buffer.

Selects get_texture() or get_gpu_texture() at compile time based on which the concrete buffer type exposes. Returns nullptr if the buffer has not yet produced a GPU texture.

Template Parameters

T	A type satisfying GpuImageSource.

Parameters

buffer

The pixel-bearing buffer to query.

Returns

GPU-resident VKImage, or nullptr.
