Proposed: Process the glTF2 input file and return it as is

The Context

We are working on a project that involves the use of the Elixir Membrane Framework. Our goal is to process glTF (GL Transmission Format) files, which are standard file formats for 3D scenes and models.

The Problem Statement

We need to create a job in the Membrane Framework that can take an input glTF file and return it as is. However, we are currently stuck and unable to proceed with this task.

Describe how your proposal will work with code, pseudo-code, mock-ups, or diagrams

defmodule MyPipeline do
  use Membrane.Pipeline

  @impl true
  def handle_init(_) do
    children = %{
      source: %Membrane.File.Source{location: "input.gltf"},
      sink: Membrane.File.Sink
    }

    links = [
      link(:source)
      |> to(:sink)
    ]

    {{:ok, %ParentSpec{children: children, links: links}}, %{}}
  end
end

This is a basic pipeline that reads a file and writes it back out. It’s not doing any processing yet, but it’s a start.

The Benefits

Implementing this feature will allow us to process glTF files within our application, opening up new possibilities for 3D model manipulation and visualization.

The Downsides

The main downside is the complexity involved in understanding and implementing the Membrane Framework. This could potentially slow down development time.

The Road Not Taken

An alternative approach would have been to use a different framework or language that might be easier to implement but may not offer the same level of control and flexibility as the Membrane Framework.

The Infrequent Use Case

This feature may not be used frequently if our application does not heavily rely on 3D model manipulation.

In Core and Done by Us

This feature will be implemented by the V-Sekai development team.
