# Test-Drive-3-Maps

Reverse engineered and extracted maps of the DOS Game *Test Drive III: The Passion* by Accolade

As a kid, I played Test Drive III a lot. Not because of the racing, but simply to explore the world.

There was so much to see, so much to discover. This project is an attempt to reconstruct those maps as accurately as possible. 
Over the past five years, I have worked on it on and off. Now, with the help of AI, I am close to success. Apart from the occasional flying car and missing sprites.

The 3D format itself is nothing too exotic, but it does contain a few special cases. Each tile or object is a small mesh stored as three parallel arrays of 16-bit signed X, Y, and Z vertex coordinates, followed by 8-byte polygon records containing the polygon type, vertex indices, and palette color. These are preceded by a short 4- or 8-byte header.

A map is a 32×16 grid. Each cell is 2 bytes: a tile ID selecting one of those meshes, plus packed rotation and height bits.

Wavefront Object files are available in the objs directory.

## Development

### Prerequisites
- Node.js 20.19+ (required by Vite 7)

### Installation
```bash
npm install
```

### Running the Browser Viewer
```bash
npm run dev
```
Opens the viewer at http://localhost:5173

### Building for Production
```bash
npm run build
```
Output is in the `dist/` directory.

### Exporting OBJ Files
```bash
npm run export
```
Exports all maps and objects to the `objs/` directory.

### Exporting PNG Images
```bash
npm run imgextract
```
Exports the currently documented DAT images as indexed-color PNGs to the `images/` directory.

### Exporting Scene Sprites
```bash
npm run spriteextract
```
Extracts transparent scene-sprite PNGs from the known scene render descriptor banks, including the `SCENE02` same-family variant.

### CLI Tools
```bash
# View LST file contents
npm run lstview -- public/base/SCENE01.LST

# Extract VGA image from DAT file
npm run imgview -- public/base/DATAB.DAT 0x151 12083 320
```

## Extracted Images Gallery

For a visual overview and previews of all extracted UI assets, scene sprites, map palettes, and car designs, visit the **[Project Images Gallery Index](images/README.md)**. Each individual directory contains its own generated visual gallery:
- [📁 Corvette ZR-1 Asset Gallery](images/CCERV/README.md)
- [📁 Honda NSX Asset Gallery](images/CCNSX/README.md)
- [📁 Lamborghini Diablo Asset Gallery](images/CDIAB/README.md)
- [📁 Mythos Asset Gallery](images/CMYTH/README.md)
- [📁 Chevrolet Corvette Stelvio Asset Gallery](images/CSTEL/README.md)
- [📁 Scenery Sprites Galleries](images/SCENE01_SPRITES/README.md)

## File Format Specifications

The `spec/` directory contains reverse-engineered documentation for Test Drive III file formats:

| [map-format.md](spec/map-format.md) | Race-track map format: tile grid, object placement block, color table, and header parameter struct |
| [scene-render-descriptor-bank-format.md](spec/scene-render-descriptor-bank-format.md) | Scene render descriptor bank family used by `SCENE01.DAT`, `SCENE02.DAT`, and `SCENETT1.DAT` |
| [lst-file-format.md](spec/lst-file-format.md) | LST resource index files (scene and car variants) |
| [image-format.md](spec/image-format.md) | VGA image compression (LZW + RLE pipeline) |
| [palette-format.md](spec/palette-format.md) | VGA palette handling and color selection |
| [color_remap.md](spec/color_remap.md) | Paired-pixel lookup tables for sky/horizon gradient and road remapping |
| [references.md](spec/references.md) | External reverse-engineering references and links |
