GeometryBuffer()

MayaFlux::Buffers::GeometryBuffer::GeometryBuffer ( std::shared_ptr< Nodes::GpuSync::GeometryWriterNode >  node, const std::string &  binding_name = "geometry", float  over_allocate_factor = 1.5f  )

explicit

Create geometry buffer from generative node.

Parameters

node	GeometryWriterNode that generates vertices each frame
binding_name	Logical name for this geometry binding (default: "geometry")
over_allocate_factor	Buffer size multiplier for dynamic growth (default: 1.5x)

Buffer size is initially set to node->get_vertex_buffer_size_bytes(). If over_allocate_factor > 1.0, buffer will be larger to accommodate growth without reallocation.
