GeometryReadbackNode()

MayaFlux::Nodes::GpuSync::GeometryReadbackNode::GeometryReadbackNode ( std::shared_ptr< Buffers::VKBuffer >  buffer, size_t  vertex_count = 0  )

explicit

Construct from a GPU vertex buffer.

Parameters

buffer	GPU vertex buffer to download from. Must remain valid for the lifetime of this node.
vertex_count	Expected number of MeshVertex elements. Used to size the readback vector. If 0, the count is derived from buffer->get_size_bytes().
