release: Fox v1.1 "Ares" — Stage-Based Pipeline & Radar Parity
release: Fox v1.1 "Ares" — Stage-Based Pipeline & Radar Parity
This release marks a major architectural shift and achieves full feature parity with the high-fidelity Shenron radar testbench. Architecture: - Implemented PipelineManager and Stage-based execution (Sim, Shenron, MCAP, Video). - Decoupled recorder from physics/augmentation logic into src/processing/physics.py. - Migrated all path resolution to Pathlib for cross-platform robustness. Radar & Metrology: - Integrated FastHeatmapEngine for stateful, high-performance RD/RA/CFAR rendering. - Implemented dual-plot Range-Azimuth (Static Absolute vs Dynamic Peak). - Flattened telemetry schema for direct Foxglove Plot panel compatibility. - Added hardware-accurate 3D FOV frustum projections (LINE_LIST). Dashboard & UX: - Bumped version to v1.1. - Fixed stop.flag detection bug in simulation shutdown. - Optimized GPU headroom by maintaining idle/sync mode during synthesis.

# Implementation Plan: Stage-Based Pipeline Refactor |
|||
|
|||
Refactor the Fox CARLA ADAS simulation pipeline to separate concerns across environment management, data processing, and serialization. This moves the project from a monolithic `main.py` to a modular, stage-based architecture. |
|||
|
|||
## User Review Required |
|||
|
|||
> [!IMPORTANT] |
|||
> **Dashboard Telemetry Persistence**: The Dashboard backend (`app.py`) parses specific `stdout` patterns like `[SHENRON_STEP]` and `[AUTO-MCAP]`. We must ensure the new `PipelineManager` or the individual stages continue to emit these strings to avoid breaking the UI progress bars. |
|||
|
|||
> [!WARNING] |
|||
> **Resource Management**: During the transition from `SimulationStage` to `ShenronStage`, we must explicitly ensure CARLA's synchronous mode is either released or the process is handled such that GPU memory is freed for the heavy Shenron Torch operations. |
|||
|
|||
## Proposed Changes |
|||
|
|||
--- |
|||
|
|||
### [NEW] Pipeline Core (`src/pipeline/`) |
|||
|
|||
Establish the foundational classes for stage-based execution. |
|||
|
|||
#### [NEW] [base.py](file:///d:/CARLA/CARLA_0.9.16/PythonAPI/Fox/src/pipeline/base.py) |
|||
- Define `PipelineContext`: Dataclass to carry `session_path`, `scenario_config`, and `args`. |
|||
- Define `PipelineStage`: Abstract Base Class with `run(context)` and `cleanup()` methods. |
|||
|
|||
#### [NEW] [manager.py](file:///d:/CARLA/CARLA_0.9.16/PythonAPI/Fox/src/pipeline/manager.py) |
|||
- Implement `PipelineManager`: Orchestrates the execution of a list of `PipelineStage` objects. |
|||
- Handles error propagation and graceful halts. |
|||
|
|||
--- |
|||
|
|||
### [NEW] Processing Layer (`src/processing/`) |
|||
|
|||
Extract physics and data-augmentation logic to make it reusable and testable. |
|||
|
|||
#### [NEW] [physics.py](file:///d:/CARLA/CARLA_0.9.16/PythonAPI/Fox/src/processing/physics.py) |
|||
- **`calculate_radial_velocity`**: Extracted from `recorder.py`. Calculates line-of-sight velocity for LiDAR points. |
|||
- **`compute_adas_metrics`**: Extracted from `recorder.py`. Calculates range, azimuth, and closing velocity for NPCs. |
|||
|
|||
--- |
|||
|
|||
### [MODIFY] Simulation & Recording |
|||
|
|||
Clean up existing components to focus on their primary responsibilities. |
|||
|
|||
#### [MODIFY] [recorder.py](file:///d:/CARLA/CARLA_0.9.16/PythonAPI/Fox/src/recorder.py) |
|||
- Remove physics calculation logic. |
|||
- Update `save()` to accept pre-calculated metrics. |
|||
- Move `_generate_videos` to a utility function. |
|||
|
|||
#### [MODIFY] [main.py](file:///d:/CARLA/CARLA_0.9.16/PythonAPI/Fox/src/main.py) |
|||
- Remove monolithic simulation loop. |
|||
- Transform into a thin wrapper that initializes `PipelineManager` with `SimStage`, `ShenronStage`, and `McapStage`. |
|||
|
|||
--- |
|||
|
|||
### [NEW] Pipeline Stages (`src/pipeline/stages/`) |
|||
|
|||
Encapsulate logic into discrete execution units. |
|||
|
|||
#### [NEW] [sim_stage.py](file:///d:/CARLA/CARLA_0.9.16/PythonAPI/Fox/src/pipeline/stages/sim_stage.py) |
|||
- Port the CARLA simulation loop from `main.py`. |
|||
- Manage `SensorManager` and `Recorder` lifecycles. |
|||
|
|||
#### [NEW] [shenron_stage.py](file:///d:/CARLA/CARLA_0.9.16/PythonAPI/Fox/src/pipeline/stages/shenron_stage.py) |
|||
- Wrap `scripts/generate_shenron.py` logic. |
|||
- Ensure `[SHENRON_STEP]` telemetry is emitted. |
|||
|
|||
#### [NEW] [mcap_stage.py](file:///d:/CARLA/CARLA_0.9.16/PythonAPI/Fox/src/pipeline/stages/mcap_stage.py) |
|||
- Wrap `scripts/data_to_mcap.py` logic. |
|||
- Register Foxglove schemas and handle final serialization. |
|||
|
|||
--- |
|||
|
|||
## Verification Plan |
|||
|
|||
### Automated Tests |
|||
- **Physics Parity Test**: Create a script in `scratch/` that runs the old `recorder.py` logic and the new `physics.py` logic on the same frame to ensure bit-identical results for radial velocity and ADAS metrics. |
|||
- **Pipeline Dry-Run**: Run the pipeline with `--skip-sim` on an existing data folder to verify that `ShenronStage` and `McapStage` correctly identify and process the files. |
|||
|
|||
### Manual Verification |
|||
- **Dashboard Validation**: Launch the Dashboard via `dashboard.bat`, trigger a simulation, and verify that: |
|||
1. The console log shows the new stage transitions. |
|||
2. The progress bars for Shenron and MCAP update correctly. |
|||
- **Foxglove Check**: Open the generated `.mcap` in Foxglove and verify that the LiDAR (with radial velocity) and Radar pointclouds are visualized correctly. |

# Fox v1.1 Release Walkthrough |
|||
|
|||
This release marks a major architectural shift from a monolithic script to a modular, stage-based pipeline, while simultaneously achieving full feature parity with the high-fidelity `test_shenron.py` radar testbench. |
|||
|
|||
## 🚀 Key Achievements |
|||
|
|||
### 1. Unified Radar Physics & Visualization |
|||
- **Single Source of Truth**: All radar plotting and post-processing logic is now centralized in `scripts/ISOLATE/sim_radar_utils/plots.py`. |
|||
- **FastHeatmapEngine**: Migrated the production pipeline to the stateful rendering engine, resulting in consistent dB scaling and improved performance. |
|||
- **Dual RA Stream**: Range-Azimuth (RA) visualization now produces both a **Static** (absolute magnitude) and **Dynamic** (peak-tracking) stream for Foxglove. |
|||
- **3D FOV Frustums**: Added hardware-accurate 3D frustum wireframes for all radar types (AWRL1432 and RadarBook). |
|||
|
|||
### 2. Modular Stage-Based Pipeline |
|||
- **PipelineManager**: Orchestrates the execution of discrete stages: `Simulation` → `Shenron` → `MCAP` → `Video`. |
|||
- **Feature Parity**: Ported advanced telemetry flattening and metrology math from the testbench to the production exporter. |
|||
- **Selective Execution**: New CLI flags allow running only specific stages (e.g., `--only-mcap` to re-process existing data). |
|||
|
|||
### 3. Robustness & Portability |
|||
- **Pathlib Integration**: Replaced brittle `os.path` joins with robust `Pathlib` logic in all pipeline stages and the orchestrator. |
|||
- **Stop Flag Detection**: Fixed a path bug in the stop flag detection to ensure graceful simulation shutdown works reliably across different working directories. |
|||
- **Hardware Persistence**: Added `radar_specs.json` generation to save hardware constants (carrier frequency, velocity limits) during synthesis for downstream visualization. |
|||
|
|||
## 🛠️ Verification Results |
|||
|
|||
| Component | Status | Verification Detail | |
|||
|---|---|---| |
|||
| **Dashboard** | ✅ | Version bumped to v1.1; scenario list and status polling verified. | |
|||
| **SimStage** | ✅ | Verified ego spawn, weather application, and `stop.flag` path resolution. | |
|||
| **ShenronStage** | ✅ | Verified `sys.path` injection and telemetry event emission. | |
|||
| **McapStage** | ✅ | Verified `FastHeatmapEngine` initialization and `ISOLATE` path handling. | |
|||
| **Telemetry** | ✅ | Verified flattened schema for Foxglove Plot panel compatibility. | |
|||
|
|||

Augment raw semantic LiDAR data with per-point radial velocity. |

Takes the 6-column CARLA semantic LiDAR output [x, y, z, cos, obj, tag] |
