Add utilities nodes in Meshroom

[Alxiice]

Description

Add new general nodes :

• InputString
• InputInt
• GetParentFolder : get the parent folder of a path
• GenerateMeshroomScene : generate a meshroom scene based on a template and node overrides
• MeshroomSceneParameter : utility tool to create overrides strings used on the GenerateMeshroomScene node
• ComputeMeshroomScene : launch the compute/submit on a meshroom scene

How to use these nodes

I'll skip the InputString, InputInt & GetParentFolder that are pretty straightforward.

For the other nodes here is a pipeline example :

Here is the node breakdown :

• MeshroomSceneParameter :
  

  • Node is the node instance name (or node type) to override
  • Parameter is the parameter name. For input overrides you must leave this empty and for parameter overrides you must fill it.
  • Value is the value it will be set to. If empty the output will be set to an empty string to avoid errors.
  • Mode is either node_instance (override only one node instance) or node_type (override all nodes from a specific type).

• GenerateMeshroomScene :
  

  • Template is the template scene
  • Scene Path is the scene destination. If empty it will be a scene.mg file in the node internal folder
  • Input Overrides are the overrides for input nodes (CameraInit)
  • Parameters Overrides are the overrides for other nodes
  • Invalidation String can be used to set an invalidation string on all nodes (to make sure the graph is unique)
  • Meshroom Scene will be set to the created scene file

• ComputeMeshroomScene :
  

  • Scene is the path to the meshroom scene file
  • Force Compute can be set to True to compute nodes even if their status is success.
  • Submit can be used to submit on farm (in opposition to compute locally)
  • Submitter can be used to select the submitter
  • Submit Label can be used to set the submitted job name
