RFP_Infinity-Vis/Infinity_Vis_1/FEATURE_INVENTORY.md

Current Feature Inventory

This inventory was collected from the current app/ codebase and is the scope target for the clean rebuild.

Core control flow

• Mapping/project open, save, and save-as
• Startup auto-load of sample mapping
• Live scene and Next scene
• FOH mode with Go and Fade Go
• Tempo transport and transition time control
• Utility modes such as blackout and single-tile white test

Pattern system

Current built-in patterns:

• solid
• checker
• row_gradient
• column_gradient
• center_pulse
• sparkle
• breathing
• wave_line
• scan
• arrow
• scan_dual
• sweep
• saw
• two_dots
• strobe
• stopwatch
• snake

Pattern parameter surface in the current app includes:

• brightness
• fade / smoothing
• tempo multiplier
• direction
• checker mode
• scan style and angle
• on/off width
• band thickness
• flip horizontal / vertical
• strobe mode and duty cycle
• stopwatch mode
• color mode
• primary / secondary colors
• palette
• symmetry
• center pulse mode
• step size
• block size
• pixel group size
• randomness

Preview and UI

• Main desktop Qt window
• Pattern panel
• Preset browser
• Tile preview / technical preview / LEDs-only preview
• Fullscreen preview window
• Selected tile panel
• Utility controls
• Output diagnostics panel

Mapping and editing

• XML mapping load/save/validation
• Tile table editing
• Segment table editing
• Raw XML editor
• Calibration and enable flags per tile
• Controller IP / host / name / MAC metadata persistence

WLED-assisted mapping

• Network scan for WLED devices
• Device discovery via /json/info and /json
• Per-device identify action
• Tile assignment workflow inside Mapping Settings
• Immediate persistence back to the mapping file

Presets

• JSON-backed preset storage
• Seed presets on first run
• Save, load, and delete presets

Output

• Preview backend
• DDP backend for WLED
• Art-Net backend seam
• Output enable/disable
• Output FPS target
• Render FPS / Send FPS / Output health diagnostics
• Controller-side FPS polling for WLED live mode

Performance pain points in the current code

• A lot of per-frame object churn:
  • PreviewFrame
  • TileFrame
  • TilePatternSample
  • many RGBColor instances
  • nested dict[str, list[RGBColor]] payloads
• Per-frame rebuilding of LED pixel lists for each segment
• Preview and output coordination still centered around one controller loop
• Multiple render engines and transition helpers duplicating state
• DDP payload generation starts from nested Python objects instead of a compact frame buffer

Rebuild priorities for Infinity_Vis_1

• fixed-size runtime state
• lower per-frame allocation
• preview cadence separated from hardware output cadence
• controller-first payload generation
• shared-IP multi-tile controller topology as a first-class concept
• clean feature layering so UI, preview, render, and output can scale independently
