Scene Overview

Top-Level Node Connections

f_00_* → f_... → f_N_* → Figures_preview → SHOW_TIMELINE → TAKEOFF_AND_LANDING

The scene has three independent pipelines and several standalone tools:

1. Figure Pipeline

Each f_0X_* geo container holds a formation (drone positions and colors for one figure). They chain via object-level connections. The last in chain feeds into Figures_preview, which contains a static_preview HDA.

Details:

• Formation_0 / Formation_1 / Formation_2 → Timeshift_0/1/2 (frame-locked object merges inside Figures_preview)
• Figures_preview HDA collects all formations via object_merge and uploads to server

2. Show Animation Pipeline (SHOW_TIMELINE → TAKEOFF_AND_LANDING)

SHOW_TIMELINE

Formation_0 ─┐
             ├──→ Main_animation_flow_0 (morf_tool)
Formation_1 ─┘                  │
                                ↓
  Formation_2 ──→ Main_animation_flow_1 (morf_tool)
                                │
                                ↓
  Formation_N ──→ Main_animation_flow_N (morf_tool)
                                │
                                ↓

                            Show_solver
                                │
                                ↓
                            rop_alembic

• Formation_0 / Formation_1 / Formation_N — object_merge nodes referencing figure containers from the Figure Pipeline
• Main_animation_flow_* — morf_tool transition from Formation_0 → Formation_1 with timing, falloff, inflation settings
• bookmarks_control — null node with bookmarks for transition markers
• Show_solver — animation_sim HDA running the physics simulation (collision avoidance, speed/acceleration limits)
• rop_alembic — Alembic output

TAKEOFF_AND_LANDING

  drones_base_position  —  drone start positions
            │
            ↓
          Show (alembic)  —  load the animation
            │
            ↓
        Takeoff_sim  —  compute takeoff (→ rop_alembic1)
            │
            ↓
        Takeoff (alembic)  —  load the takeoff
            │
            ↓
        controller  —  press [set good transition values]
            │
            ↓
      Landing_sim  —  compute landing (→ rop_alembic2)
            │
            ↓
        Landing (alembic)  —  load the landing
            │
            ↓
        controller  —  press [set good transition values] again
            │
            ↓
      rop_alembic3  —  review animation and write everything 

• Takeoff_sim/Landing_sim — takeoff_landing HDA: simulates drones lifting from ground to show positions with queue-based launch
• Takeoff_Show / blendShow_Landing — blendshape transitions between takeoff → show → landing
• Three rop_alembic nodes writing takeoff (1), landing (2), and full blended animation (3)

3. Standalone Tools

Checker (/obj/Checker)

Validates drone show animation from an Alembic file. Runs distance, speed, and acceleration checks. Prints violation tables to console.

Show_preview (/obj/Show_preview)

Generates a preview animation from a config file and Alembic cache, uploads to server, and returns a preview URL: https://dronatello.com/show_preview/?project_name=<name>

Show_site_data (/obj/Show_site_data)

Loads a show config .cfg file and displays site info: show name, drone count, altitude bounds, animation dimensions. Can load a site map.
