Fractal Dendrites
Fractal dendrites are branching, tree-like structures that occur naturally in many systems. From lightning bolts to river networks, from neural networks to crystal growth, dendrite patterns represent one of nature's most fundamental organizational principles.
What are Dendrites?
The word "dendrite" comes from the Greek word "dendron," meaning tree. In mathematics and physics, dendrites are fractal structures characterized by:
- Self-similarity: Branches resemble the whole structure at different scales
- Recursive growth: Each branch spawns smaller branches following the same rules
- Finite ramification: Branching follows specific geometric constraints
- Scale invariance: Patterns look similar at different magnifications
Generation Algorithm
Our dendrite generator uses a recursive algorithm:
- Start with a main trunk (root segment)
- At each endpoint, create multiple branches at specified angles
- Scale down the length of new branches by a ratio factor
- Repeat the process for each new branch endpoint
- Continue until maximum iterations or minimum length is reached
Mathematical Parameters
- Branching Angle: Controls the spread of branches (15°-90°)
- Length Ratio: How much each generation shrinks (0.3-0.9)
- Branch Count: Number of sub-branches per node (2-5)
- Iterations: Depth of recursion (3-12 levels)
- Thickness Decay: How line width decreases with depth
Natural Examples
- Lightning: Electrical discharge follows dendrite patterns
- River Systems: Watersheds form dendritic drainage patterns
- Blood Vessels: Circulatory systems use dendrite branching
- Neural Networks: Neurons have dendritic branches for signal reception
- Crystal Growth: Many crystals grow in dendrite patterns
- Coral Reefs: Coral structures often exhibit dendrite geometry
Applications
- Computer Graphics: Procedural generation of trees and plants
- Network Design: Efficient distribution systems
- Art and Design: Creating organic, natural-looking patterns
- Architecture: Structural designs inspired by natural branching
- Urban Planning: Street and infrastructure layout optimization
Color Schemes
- Depth-based: Colors change with branch generation
- Gradient: Smooth color transitions along branches
- Rainbow: Full spectrum color mapping
- Natural: Earth tones mimicking real trees
- Fire: Hot colors representing energy flow
Fractal Properties
- Fractal Dimension: Between 1 and 2, depending on parameters
- Hausdorff Dimension: Measures the space-filling properties
- Box-counting Dimension: Quantifies complexity at different scales
- Self-similarity Ratio: Relationship between parent and child branches
Interesting Facts
- The optimal branching angle for trees is approximately 137.5° (golden angle)
- Dendrite patterns minimize energy while maximizing surface area
- The same mathematical rules govern growth from microscopic to geological scales
- Dendrite structures can be found in both living and non-living systems
