This interactive tree fractal grows recursively from a trunk, splitting into branches whose length and angle change with mouse position. The Canvas API renders the structure, while a seeded pseudo-random number generator introduces stochastic variation, causing some branches to continue straight while others bifurcate. The drawing updates on mousemove events, with horizontal position controlling branch length ratio and vertical position adjusting angle difference. The code scales the canvas for high pixel density displays using devicePixelRatio.

Tree Fractal

An interactive tree fractal drawn on a Canvas element responds to mouse movement, which controls branch length ratio and angle difference. The rendering uses raw Canvas API calls like `beginPath`, `lineTo`, and `stroke` to recursively draw branching lines to a depth of 11. High-resolution displays are supported via `window.devicePixelRatio` scaling. The example is based on HTML5 Examples and adapts its rendering for high pixel density screens.

Tree Fractal Example

An interactive tree fractal rendered on a Canvas element responds to mouse movement by altering branch length ratio and angle difference. The code uses the Canvas 2D API with `beginPath`, `lineTo`, and `stroke` to draw recursive branches up to a depth of 11. It accommodates high pixel density displays via `window.devicePixelRatio` and `c.scale`. Mouse position maps directly to the branching parameters, updating the tree in real time.

fractal tree

An interactive fractal tree responds to mouse movement, with branching angle and length ratio changing based on cursor position. The visualization renders a recursive binary tree structure using the Canvas 2D API, drawing line segments for 13 levels of branching. It accommodates high pixel density displays by scaling the canvas using the device pixel ratio. Mouse events trigger redraws that update branch thickness and divergence angles, creating a dynamic, explorable organic form without any external data source.

Fork of Tree Fractal

An interactive tree fractal rendered on Canvas, where the branching pattern changes in response to mouse movement. The visualization draws a recursive, branching structure from a central trunk, with horizontal mouse position controlling branch length ratio and vertical position controlling the angle between branches. It uses the Canvas 2D API with recursive `drawTree` calls, and accommodates high pixel density displays by scaling the canvas using `devicePixelRatio` and CSS dimensions. The code adapts an example from HTML5Examples.

Fractal-Tree-Page

This interactive visualization displays a fractal tree that responds to mouse movement. The branching pattern changes dynamically as the user moves the cursor across the canvas. The code uses the Canvas API with high-resolution display support via `window.devicePixelRatio` and scaling. It draws recursive branches using trigonometric functions, with mouse position controlling the branch length ratio and angle difference. The tree is rendered in real-time using the `drawTree` recursive function and `stroke()` commands on the 2D context.

Tree Fractal

This interactive visualization renders a branching tree fractal on an HTML5 Canvas. Mouse movement dynamically changes the branch length ratio and angle difference, altering the tree's shape in real time. The code uses the Canvas API’s `getContext('2d')`, `moveTo`, `lineTo`, and `stroke` methods to draw recursive branches. The tree structure emerges from a recursive `drawTree` function that splits into left and right branches until reaching a depth of zero, with each branch’s length and angle determined by cursor position.

Fork of Tree Fractal

This interactive tree fractal responds to mouse movement, changing its branch length ratio and angle difference as the cursor moves across the canvas. A recursive function draws the branching structure, with red circles at terminal nodes. The code uses the Canvas 2D API with high-resolution scaling via `devicePixelRatio`, clearing and redrawing the tree on each mouse move event.

Fork of Tree Fractal

This interactive tree fractal responds to mouse movement. The branching angle and branch length ratio change based on the cursor's horizontal and vertical position, dynamically altering the tree's shape in real time. The visualization uses the Canvas API with `drawTree` recursion, `beginPath`, `moveTo`, `lineTo`, and `stroke` to render branches, incorporating high-resolution display scaling via `window.devicePixelRatio`. The code originates from HTML5 Examples and is adapted for high pixel density screens.
