Tree Generation and Texture System Improvements

1. Tree Generation Implementation

Core Components

• TreeGenerator Class: Handles tree generation in the voxel world
• Generation Parameters:
  • MIN_TREE_HEIGHT: 6 blocks
  • MAX_TREE_HEIGHT: 10 blocks
  • MAX_LEAF_DISTANCE: 5 blocks
  • MIN_TREE_SPACING: 4 blocks
  • TREE_INFLUENCE_RADIUS: 3 blocks

Tree Generation Algorithm

1. Position Validation

   isValidTreePosition(worldX, worldZ, height, heightMap, localX, localZ)
   
   

   • Checks if ground is flat
   • Ensures proper distance from water
   • Verifies height requirements

2. Tree Distribution

   shouldPlaceTree(worldX, worldZ, biomeType, height)
   
   

   • Uses Simplex noise for natural distribution
   • Different probabilities per biome:
     • Forest: 25% chance (noise > 0.75)
     • Plains: 8% chance (noise > 0.92)

3. Tree Structure Generation

   • Trunk generation
   • Leaf layer generation:
     • Top layer (1 block radius)
     • Middle layers (2 block radius)
     • Bottom layer (2 block radius, sparser)

Spacing Implementation

hasEnoughSpacing(x, z, treePositions) {
    // Checks surrounding area within TREE_INFLUENCE_RADIUS
    // Ensures MIN_TREE_SPACING between trees
}

2. Web Worker Integration

Worker Communication

self.onmessage = function(e) {
    switch (e.data.type) {
        case 'init':
            // Initialize TreeGenerator
        case 'generateChunk':
            // Generate chunk with trees
    }
}

Chunk Generation Process

1. Generate height and biome maps
