# Tesla Car Image Assets
This document describes how Tesla car images are fetched and mapped for MateDroid.
## Overview
Tesla provides a compositor service that generates car renders based on configuration options. The images are downloaded at build time using `util/fetch_tesla_assets.py` and bundled into the APK.
## Compositor Endpoints
Tesla has **two different compositor APIs**:
### Old Compositor (Legacy Models)
- **URL**: `https://static-assets.tesla.com/v1/compositor/`
- **For**: Pre-2024 Model 3, Pre-2025 Model Y
- **Output**: PNG with transparency
- **File size**: ~100-140 KB per image
**Example URL**:
```
https://static-assets.tesla.com/v1/compositor/?model=m3&view=STUD_3QTR&size=800&options=PMNG,W38B&bkba_opt=1
```
**Parameters**:
| Parameter | Description | Example |
|-----------|-------------|---------|
| `model` | Model code | `m3`, `my` |
| `view` | Camera angle | `STUD_3QTR` |
| `size` | Image width | `800` |
| `options` | Comma-separated codes | `PMNG,W38B` |
| `bkba_opt` | Background (1=transparent) | `1` |
### New Compositor (Highland/Juniper)
- **URL**: `https://static-assets.tesla.com/configurator/compositor`
- **For**: Model 3 Highland (2024+), Model Y Juniper (2025+)
- **Output**: PNG with transparency (using `bkba_opt=1`)
- **File size**: ~50-80 KB per image
**Example URL**:
```
https://static-assets.tesla.com/configurator/compositor?context=design_studio_2&options=$MT370,$PPSW,$W38A,$IPB3&view=STUD_3QTR&model=m3&size=800&bkba_opt=1
```
**Note**: We use `STUD_3QTR` view for both compositors for consistent car sizing across all models.
**Parameters**:
| Parameter | Description | Example |
|-----------|-------------|---------|
| `context` | API context | `design_studio_2` |
| `model` | Model code | `m3`, `my` |
| `view` | Camera angle | `STUD_FRONT34` |
| `size` | Image width | `800` |
| `options` | `$`-prefixed codes | `$MT370,$PPSW,$W38A,$IPB3` |
| `bkba_opt` | Background (1=transparent PNG, 2=opaque JPEG) | `1` |
**Important**: New compositor uses `$` prefix for all option codes!

## Model Mappings
### TeslamateAPI Model → Compositor Model Code
| TeslamateAPI `car_details.model` | Compositor Code | Notes |
|----------------------------------|-----------------|-------|
| `3` | `m3` | Model 3 |
| `Y` | `my` | Model Y |
| `S` | `ms` | Model S |
| `X` | `mx` | Model X |
### Internal Model Variants (for asset naming)
| Variant | Description | Compositor | File Prefix |
|---------|-------------|------------|-------------|
| Legacy Model 3 | Pre-2024 | Old | `m3` |
| Highland Model 3 | 2024+ | New | `m3h` |
| Highland Model 3 Performance | 2024+ Perf | New | `m3hp` |
| Legacy Model Y | Pre-2025 | Old | `my` |
| Juniper Model Y | 2025+ Standard/Premium | New | `myj` |
| Juniper Model Y Performance | 2025+ Performance | New | `myjp` |
| Model S | All | Old | `ms` |
| Model X | All | Old | `mx` |
### Highland/Juniper Trim Codes
| Trim Code | Model | Variant | Interior Code |
|-----------|-------|---------|---------------|
| `MT369` | Model 3 Highland | Standard | `IPB2` |
| `MT370` | Model 3 Highland | Premium | `IPB3` |
| `MT371` | Model 3 Highland | Performance | `IPB4` |
| `MTY68` | Model Y Juniper | Standard/Long Range | `IBB3` |

| `MTY60` | Model Y Juniper | Premium (20") | `IPB8` |
| `MTY53` | Model Y Juniper | Performance | `IPB10` |
**Note on Model Y Juniper compositor support:**
- `MTY68` works with `STUD_3QTR` view for 3 colors (PPSW, PN01, PX02) with 18"/19" wheels
- `MTY52` has limited support on `STUD_3QTR` - we use `MTY68` with 19" wheels instead
- `MTY60` works with `STUD_3QTR` view for 5 colors (PPSW, PN01, PX02, PN00, PR01) with 20" wheels
- `MTY53` works with `STUD_3QTR` view for all 6 colors with 21" wheels
### Model Y Juniper Trim Badging (from TeslamateAPI)
| Trim Badge | Variant | Default Wheels | Notes |
|------------|---------|----------------|-------|
| `50` | Standard Range | 18" Photon (WY18P) | |
| `74`, `74D` | Long Range/Premium | 19" Crossflow (WY19P) | |

## Gotchas and Known Issues
### 1. Placeholder Images from Old Compositor
The old compositor returns **grayscale shadow placeholders** (~26KB) for color/wheel combinations that don't exist. These look like car silhouettes but are not usable images.
**Detection**: Check file size. Valid images are 100KB+, placeholders are ~26KB.
### 2. New Colors Don't Work on Old Compositor
Colors introduced with Highland/Juniper (`PN00`, `PN01`, `PR01`, `PX02`) return placeholders on the old compositor. Must use the new compositor for these colors.
### 3. Highland/Juniper Have Limited Wheel Options
- Highland Model 3: Only `W38A` (standard) or `W30P` (Performance)
- Juniper Model Y: Only `WY18P`
Each trim level has exactly ONE wheel option available.
### 4. Highland/Juniper Detection from TeslamateAPI
TeslamateAPI doesn't explicitly indicate if a car is Highland/Juniper. Detection heuristics:
1. **Color-based**: If exterior color is `PN00`, `PN01`, `PR01`, or `PX02` → Highland/Juniper
2. **Wheel-based**: If wheel type is Highland/Juniper-only:
- Model 3: `Photon18`, `Glider18`, `Nova18` → Highland
- Model Y: `Photon18` → Juniper
This correctly identifies Highland/Juniper cars even with common colors like Pearl White (`PPSW`).
### 5. Trim Badging for Performance Detection
- Legacy: `P` prefix (e.g., `P74D`) indicates Performance
- Highland: Uses `MT371` trim code
### 6. Model S/X Support
The old compositor supports Model S (`ms`) and Model X (`mx`) with legacy colors. Both models are now included with 5 colors each.
### 7. Discontinued Colors
- `PR00` (Midnight Cherry Red): Was briefly available, now discontinued. Compositor may still work but we don't download.
### 8. Missing Wheel Options in Compositor
Some newer wheel options are not yet available in Tesla's compositor:
- **Nova 19"** (Highland M3): TeslamateAPI reports as "Helix19" - falls back to W38A (18" Photon) visually
### 9. bkba_opt Parameter Controls Output Format
Both compositors support the `bkba_opt` parameter:
- `bkba_opt=1`: Transparent PNG (used for all images)
- `bkba_opt=2`: Opaque JPEG with background
We use `bkba_opt=1` for all images to get consistent transparent PNGs.

| Juniper Model Y | 6 | 3 | 15 | PNG |
| Juniper MY Performance | 6 | 1 | 6 | PNG |

## Updating Assets
To re-download all assets:
```bash
# Preview what would be downloaded
./util/fetch_tesla_assets.py --dry-run
# Download all assets
./util/fetch_tesla_assets.py
# Download to custom directory
./util/fetch_tesla_assets.py --output-dir /path/to/assets
```
The script will:
1. Skip invalid combinations (checks response size/format)
2. Report warnings for failed downloads
3. Download in parallel batches
---
## Future Considerations
1. **New Model Variants**: When Tesla releases new refreshes (e.g., Model S/X Plaid+), new compositor codes may be needed.
2. **New Colors**: Tesla periodically introduces new colors. Check Tesla's configurator for current options.
3. **API Changes**: Tesla may deprecate or change compositor endpoints without notice.
4. **Better Highland/Juniper Detection**: Could potentially use VIN decoding or manufacture date if available from TeslamateAPI.
