ADDED Requirements

Requirement: Remote Virtual Canvas

The system SHALL provide a web-based "Virtual Canvas" that represents the projection area and allows the user to manipulate mapping surfaces (Quads and Triangles).

Scenario: Dragging a vertex

  • WHEN the user drags a vertex on the web UI
  • THEN the UI SHALL calculate the normalized (0.0 to 1.0) coordinates and send them to the backend API

Requirement: Surface Selection

The system SHALL allow the user to select, add, and delete mapping surfaces (Quads and Triangles) from the remote interface.

Scenario: Adding a new Quad

  • WHEN the user clicks the "Add Quad" button in the UI
  • THEN the UI SHALL send a command to the backend to create a new quad surface in ofxPiMapper

Requirement: Real-time Feedback

The web UI SHALL provide visual feedback for the selected surface and vertex to ensure the user knows which part of the mapping is being edited.

Scenario: Selecting a surface

  • WHEN the user taps on a surface in the virtual canvas
  • THEN the UI SHALL highlight that surface and display its specific transformation controls
