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!

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. 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.

Updating Assets

To re-download all assets:

# 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.
