MeshBuffer() [2/2]

MayaFlux::Buffers::MeshBuffer::MeshBuffer

(

std::shared_ptr< Nodes::GpuSync::MeshWriterNode >

node

)

Construct from a MeshWriterNode.

The node is polled each graphics cycle. compute_frame() is called on the node, and if its data changed, set_mesh_data() is called internally before MeshProcessor uploads.
