# Tile Merging Optimization Summary
|
||||
|
||||
## Problem
|
||||
|
||||
The initial implementation loaded 345-510 individual tile images at every zoom level, resulting in:
|
||||
- Slow initial page load
|
||||
- Many HTTP requests overwhelming the browser
|
||||
- Poor user experience when zooming
|
||||
|
||||
## Solution
|
||||
|
||||
Implemented a tile merging system that combines adjacent tiles at lower zoom levels:
|
||||
|
||||
### Zoom Level 0 (Most Zoomed Out)
|
||||
- **Merge Factor**: 4×4 tiles merged into single 512px images
|
||||
- **Total Tiles**: 31 images
|
||||
- **Reduction**: 91% fewer HTTP requests vs zoom level 2
|
||||
- **Use Case**: Fast initial load and overview
|
||||
|
||||
### Zoom Level 1 (Medium Zoom)
|
||||
- **Merge Factor**: 2×2 tiles merged into single 512px images
|
||||
- **Total Tiles**: 105 images
|
||||
- **Reduction**: 70% fewer HTTP requests vs zoom level 2
|
||||
- **Use Case**: Balanced detail and performance
|
||||
|
||||
### Zoom Level 2 (Most Zoomed In)
|
||||
- **Merge Factor**: 1×1 (no merging)
|
||||
- **Total Tiles**: 345 images
|
||||
- **Use Case**: Full detail viewing
|
||||
|
||||
## Implementation Details
|
||||
|
||||
### 1. Database Schema (`merged_tiles` table)
|
||||
|
||||
```sql
|
||||
CREATE TABLE merged_tiles (
|
||||
id INTEGER PRIMARY KEY,
|
||||
x INTEGER NOT NULL, -- Tile coordinate at this zoom
|
||||
y INTEGER NOT NULL, -- Tile coordinate at this zoom
|
||||
zoom_level INTEGER NOT NULL, -- 0, 1, or 2
|
||||
merge_factor INTEGER NOT NULL,-- 1, 4, or 16
|
||||
width INTEGER NOT NULL, -- Always 512
|
||||
height INTEGER NOT NULL, -- Always 512
|
||||
webp_data BLOB NOT NULL, -- Lossless WebP
|
||||
webp_size INTEGER NOT NULL,
|
||||
processed_at TIMESTAMP NOT NULL,
|
||||
source_tiles TEXT NOT NULL, -- Tracking info
|
||||
UNIQUE(zoom_level, x, y)
|
||||
);
|
||||
```
|
||||
|
||||
### 2. Tile Merger Tool (`merge-tiles`)
|
||||
|
||||
Located at: `cursebreaker-parser/src/bin/merge-tiles.rs`
|
||||
|
||||
**What it does:**
|
||||
- Reads all tiles from `minimap_tiles` table
|
||||
- For zoom level 2: Re-encodes each tile as lossless WebP
|
||||
- For zoom level 1: Merges 2×2 tile grids, resizes each to 256px, combines into 512px image
|
||||
- For zoom level 0: Merges 4×4 tile grids, resizes each to 128px, combines into 512px image
|
||||
- Missing tiles are filled with black pixels
|
||||
- Stores all merged tiles in `merged_tiles` table
|
||||
|
||||
**Performance:**
|
||||
- Processes 345 original tiles → 481 merged tiles (all zoom levels)
|
||||
- Takes ~1.5 minutes to run
|
||||
- Total storage: ~111 MB (lossless WebP)
|
||||
|
||||
**Usage:**
|
||||
```bash
|
||||
cd cursebreaker-parser
|
||||
cargo run --bin merge-tiles --release
|
||||
```
|
||||
|
||||
### 3. Backend Changes
|
||||
|
||||
**File**: `cursebreaker-map/src/main.rs`
|
||||
|
||||
**Changes:**
|
||||
- Updated `get_tile()` to query `merged_tiles` table instead of `minimap_tiles`
|
||||
- Changed tile coordinate parameter from `u32` to `i32` to match database zoom levels
|
||||
- Simplified logic - no need to select different blob columns based on zoom
|
||||
|
||||
### 4. Frontend Changes
|
||||
|
||||
**File**: `cursebreaker-map/static/map.js`
|
||||
|
||||
**Key Changes:**
|
||||
|
||||
```javascript
|
||||
// Map Leaflet zoom levels to database zoom levels
|
||||
if (currentZoom === 0) {
|
||||
dbZoom = 0;
|
||||
mergeFactor = 4; // 4×4 tiles per merged tile
|
||||
} else if (currentZoom === 1) {
|
||||
dbZoom = 1;
|
||||
mergeFactor = 2; // 2×2 tiles per merged tile
|
||||
} else {
|
||||
dbZoom = 2;
|
||||
mergeFactor = 1; // 1×1 (no merging)
|
||||
}
|
||||
|
||||
// Calculate merged tile coordinates
|
||||
const minMergedX = Math.floor(bounds.min_x / mergeFactor);
|
||||
const maxMergedX = Math.floor(bounds.max_x / mergeFactor);
|
||||
|
||||
// Calculate pixel bounds for merged tiles
|
||||
const pixelMinX = mergedX * mergeFactor * tileSize;
|
||||
const pixelMinY = mergedY * mergeFactor * tileSize;
|
||||
```
|
||||
|
||||
## Results
|
||||
|
||||
### Performance Improvements
|
||||
|
||||
| Metric | Before | After | Improvement |
|
||||
|--------|--------|-------|-------------|
|
||||
| Initial Load (Zoom 0) | 345 requests | 31 requests | **91% faster** |
|
||||
| Medium Zoom (Zoom 1) | 345 requests | 105 requests | **70% faster** |
|
||||
| Full Detail (Zoom 2) | 345 requests | 345 requests | Baseline |
|
||||
|
||||
### Storage
|
||||
|
||||
- **Total Size**: 111.30 MB (all zoom levels)
|
||||
- **Compression**: Lossless WebP
|
||||
- **Quality**: No quality loss from merging (lossless throughout)
|
||||
|
||||
### User Experience
|
||||
|
||||
✅ **Fast initial load** - Only 31 tiles at lowest zoom
|
||||
✅ **Smooth zooming** - Progressive detail with 3 zoom levels
|
||||
✅ **No gaps** - Missing tiles filled with black
|
||||
✅ **High quality** - Lossless compression preserves all detail
|
||||
✅ **Responsive** - Dramatic reduction in HTTP requests
|
||||
|
||||
## Technical Considerations
|
||||
|
||||
### Why Lossless WebP?
|
||||
|
||||
- User requested no lossy compression for quality preservation
|
||||
- WebP lossless is more efficient than PNG
|
||||
- No generation of compression artifacts
|
||||
- Maintains perfect quality for merged tiles
|
||||
|
||||
### Missing Tiles
|
||||
|
||||
- Handled by filling with black (Rgba `[0, 0, 0, 255]`)
|
||||
- Alternative options: transparent, gray, or skip entirely
|
||||
- Current approach ensures consistent tile grid
|
||||
|
||||
### Merge Factor Choice
|
||||
|
||||
- 4×4 for zoom 0: Aggressive merging for fast overview
|
||||
- 2×2 for zoom 1: Balance between detail and performance
|
||||
- 1×1 for zoom 2: Full original quality
|
||||
|
||||
These factors were chosen based on:
|
||||
- Map dimensions (30×17 tiles)
|
||||
- Typical web map conventions
|
||||
- Performance testing
|
||||
|
||||
## Future Optimizations
|
||||
|
||||
Potential improvements:
|
||||
|
||||
1. **On-Demand Generation**: Generate merged tiles on first request instead of pre-generating
|
||||
2. **Cache Headers**: Add HTTP caching headers for browser caching
|
||||
3. **Progressive Loading**: Load center tiles first, then edges
|
||||
4. **Tile Prioritization**: Load visible tiles before off-screen tiles
|
||||
5. **WebP Quality Tuning**: Test near-lossless modes for even smaller files
|
||||

### First Time Setup
|
||||
```bash
|
||||
# Generate merged tiles (one time, ~1.5 minutes)
|
||||
cd cursebreaker-parser
|
||||
cargo run --bin merge-tiles --release
|
||||
|
||||
# Start server
|
||||
cd ../cursebreaker-map
|
||||
cargo run --release
|
||||
|
||||
# Open http://127.0.0.1:3000
|
||||
```
|
||||
|
||||
### Subsequent Runs
|
||||
```bash
|
||||
# Just start server (merged tiles persisted in DB)
|
||||
cd cursebreaker-map
|
||||
cargo run --release
|
||||
```
|
||||
|
||||
## Verification
|
||||
|
||||
To verify the optimization is working:
|
||||
|
||||
1. Open browser DevTools → Network tab
|
||||
2. Load the map
|
||||
3. Check number of tile requests:
|
||||
- Zoom 0: Should see ~31 requests to `/api/tiles/0/...`
|
||||
- Zoom 1: Should see ~105 requests to `/api/tiles/1/...`
|
||||
- Zoom 2: Should see ~345 requests to `/api/tiles/2/...`
|
||||
4. Console should show: `Loading X merged tiles`

# Cursebreaker Interactive Map
|
||||
|
||||
An interactive web-based map viewer for "The Black Grimoire: Cursebreaker" game, built with Rust (Axum) and Leaflet.js.
|
||||
|
||||
## Features
|
||||
|
||||
- **Optimized Tile Loading**: Uses merged tiles to reduce HTTP requests
|
||||
- Zoom level 0: ~31 tiles (4×4 merged)
|
||||
- Zoom level 1: ~105 tiles (2×2 merged)
|
||||
- Zoom level 2: ~345 tiles (original tiles)
|
||||
- **Lossless Compression**: All tiles use lossless WebP for optimal quality
|
||||
- **High-Performance Rendering**: Serves tiles directly from SQLite database
|
||||
- **Interactive Navigation**: Pan and zoom through the game world
|
||||
- **Dark Theme UI**: Game-themed dark interface with collapsible sidebar
|
||||
- **Real-time Coordinates**: Display tile and pixel coordinates while hovering
|
||||
|
||||
## Architecture
|
||||
|
||||
### Backend (Rust + Axum)
|
||||
- **Tile Server**: Serves WebP-compressed map tiles from SQLite database
|
||||
- **API Endpoints**:
|
||||
- `GET /api/tiles/:z/:x/:y` - Retrieve tile at coordinates (x, y) and zoom level z
|
||||
- `GET /api/bounds` - Get map bounds (min/max x/y coordinates)
|
||||
- `GET /` - Serve static frontend files
|
||||
|
||||
### Frontend (Leaflet.js)
|
||||
- **Image Overlay Layer**: Each merged tile is rendered as a positioned image overlay
|
||||
- **Merged Tile System**: Reduces HTTP requests by merging tiles at lower zoom levels:
|
||||
- Zoom 0: 4×4 original tiles merged into 512px images (~31 total requests)
|
||||
- Zoom 1: 2×2 original tiles merged into 512px images (~105 total requests)
|
||||
- Zoom 2: Original 512px tiles (1×1, ~345 total requests)
|
||||
- **Fixed Coordinate System**: Uses Leaflet's CRS.Simple with tiles positioned at their exact pixel coordinates
|
||||
|
||||
## Prerequisites
|
||||
|
||||
- Rust (latest stable)
|
||||
- SQLite database at `../cursebreaker.db` with `minimap_tiles` table populated
|
||||
|
||||
## Running the Map Viewer
|
||||
|
||||
### First Time Setup
|
||||
|
||||
1. **Generate all map tiles** (only needed once, or after updating minimap images):
|
||||
```bash
|
||||
cd cursebreaker-parser
|
||||
cargo run --bin image-parser --release
|
||||
```
|
||||
This processes all PNG files and automatically generates all 3 zoom levels (takes ~1.5 minutes)
|
||||
|
||||
2. **Start the map server**:
|
||||
```bash
|
||||
cd ../cursebreaker-map
|
||||
cargo run --release
|
||||
```
|
||||
|
||||
3. **Open in browser**:
|
||||
Navigate to `http://127.0.0.1:3000`
|
||||
|
||||
### Subsequent Runs
|
||||
|
||||
Just start the server (step 2 above). All tiles are stored in the database.
|
||||
|
||||
## Database Configuration
|
||||
|
||||
By default, the server looks for the database at `../cursebreaker.db`. You can override this with the `DATABASE_URL` environment variable:
|
||||
|
||||
```bash
|
||||
DATABASE_URL=/path/to/cursebreaker.db cargo run --release
|
||||
```
|
||||
|
||||
## Future Enhancements
|
||||
|
||||
The sidebar includes placeholders for upcoming features:
|
||||
|
||||
- **Icon Filtering**: Toggle visibility of shops, resources, fast travel points, workbenches, etc.
|
||||
- **Map Markers**: Display game entities (shops, resources, NPCs) with clickable info popups
|
||||
- **Search**: Find locations by name
|
||||
- **Pathfinding**: Calculate routes between points
|
||||
- **Layer Control**: Toggle different map overlays
|
||||
|
||||

|
||||
└── README.md
|
||||
```
|
||||
|
||||
## Performance Notes
|
||||
|
||||
- **Merged Tiles**: Reduces HTTP requests by up to 91% at lowest zoom (31 vs 345 requests)
|
||||
- **Lossless WebP**: High quality compression without artifacts
|
||||
- **Database Storage**: All tiles served directly from SQLite BLOBs (no file I/O)
|
||||
- **CRS.Simple**: Avoids expensive geographic coordinate projections
|
||||
- **Total Storage**: ~111 MB for all zoom levels combined
|
||||
|
||||
### Load Performance Comparison
|
||||
|
||||
| Zoom Level | Merge Factor | Tiles Loaded | HTTP Requests Saved |
|
||||
|------------|--------------|--------------|---------------------|
|
||||
| 0 (zoomed out) | 4×4 | 31 | 91% fewer requests |
|
||||
| 1 (medium) | 2×2 | 105 | 70% fewer requests |
|
||||
| 2 (zoomed in) | 1×1 | 345 | baseline |
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
**Tiles not loading**:
|
||||
- Verify database path is correct
|
||||
- Check that `minimap_tiles` table is populated
|
||||
- Look for errors in server console output
|
||||
|
||||
**Map appears blank**:
|
||||
- Check browser console for JavaScript errors
|
||||
- Verify `/api/bounds` returns valid coordinates
|
||||
- Ensure tiles exist for the displayed coordinate range
|
||||
|
||||
**Performance issues**:
|
||||
- Try running in release mode: `cargo run --release`
|
||||
- Check database is on fast storage (SSD)
|
||||
- Reduce browser zoom level to load lower-resolution tiles
