Comprehensive blueprint for a headless Raspberry Pi 3B projection mapping appliance: - Unified installer with 2GB swap safety for C++ source builds. - WebSocket-driven real-time vertex/surface manipulation. - 5-tab responsive dashboard (Dashboard, Mapping, Media, Network, System). - Media validation with ffprobe (H.264 check) and resource warnings. - Throttled log streaming and explicit mapping persistence.

## Why
|
|
|
|
Currently, setting up a Raspberry Pi for projection mapping requires manually piecing together the OS, the mapping engine (`ofxPiMapper`), and various control scripts. This is fragmented, difficult to manage headlessly, and lacks a modern "appliance" feel. `ofxpimapper-full-stack` aims to unify these into a single, polished, and professional product: the Modern PocketVJ (MPVJ). It provides an "it just works" experience for artists, from the initial setup script to the real-time web-based mapping remote.
|
|
|
|
## What Changes
|
|
|
|
- **Unified Headless Installer**: A single setup script that installs the entire stack, including the `ofxPiMapper` engine, Node.js backend, and React frontend.
|
|
- **Integrated Mapping Engine**: Automated installation of `ofxPiMapper` (pre-compiled binary or source build) with a systemd service to launch fullscreen on boot.
|
|
- **Virtual Canvas 2.0**: A responsive React/Tailwind web UI for real-time vertex/surface manipulation via WebSockets, with live feedback on the beamer.
|
|
- **Enhanced Media Vault**: Complete media management (upload/delete/preview) with the ability to assign different sources (video/image/color) to individual surfaces.
|
|
- **Appliance Dashboard**: Integrated monitoring of system health (CPU, RAM, Temp) and process status, with remote power and restart controls.
|
|
- **Hybrid Networking**: A robust networking stack that maintains a permanent Access Point while allowing connection to external venue WiFi via a web interface.
|
|
|
|
## Capabilities
|
|
|
|
### New Capabilities
|
|
- `ofxpimapper-engine`: The core C++ mapping engine, integrated into the system-wide process management.
|
|
- `web-remote-dashboard`: A modern, responsive TUI-inspired web interface for full system control.
|
|
- `media-source-assignment`: The ability to dynamically map specific files or colors to specific geometric surfaces.
|
|
- `live-logs-streaming`: Real-time streaming of system and mapper logs to the web interface.
|
|
|
|
### Modified Capabilities
|
|
- `headless-installer`: Upgraded to handle the C++ engine installation and graphics driver configuration.
|
|
- `osc-bridge-api`: Expanded to handle naming, surface selection highlighting, and source assignment.
|
|
- `hybrid-network-control`: Updated with a scan-and-connect web UI while preserving the AP.
|
|
|
|
## Impact
|
|
|
|
- **Hardware**: Strictly optimized for the Raspberry Pi 3B (1GB RAM).
|
|
- **User Experience**: Transition from a "CLI-first" or "Desktop-first" workflow to a "Web-Remote-first" workflow.
|
|
- **Performance**: Heavy reliance on WebSockets and optimized C++ binaries to ensure low-latency interaction.
|
|
- **Stability**: Automated swap management and process monitoring to prevent OOM crashes during high-resolution playback.
