<h1>Fractals</h1>
<p>This page is a collection of fractals renderers I made in JS for a school assignment back in 2020. Please note that I don't use JS anymore.</p>
<h2>Fractal tree</h2>
<p>This is a fractal tree.</p>
<p>The tree splits into two parts, with an angle defined by the cursor's x positon. The number of iterations is defined by the first input field (which defaults to 12). Each branch is slightly smaller than its parent, as defined by the second input field. Click the canvas to freeze the image at any moment.</p>
<p>The splitting angle is defined by the mouses x position. The number of iterations is set in the first input field (default is 12). Each branch is slightly smaller than its parent, the factor is the second input field. Click the canvas to pause/resume the image.</p>

<h2>Mandelbrot</h2>
<p>The mandelbrot set is defined as the set of complex numbers for which a specific function (<i>F<sub>c</sub>(z) = z<sup>2</sup> + c</i>) stays within distance 2 from the origin when iterated from z=0.</p>
<h2>Mandelbrot set</h2>
<a href="https://en.wikipedia.org/wiki/Mandelbrot_set">Wikipedia page</a>
<p>You can click to zoom and set the iteration count in the input field.</p>

</div>
</div>
<h2>Multibrot set</h2>
<p>A multibrot set is a variant of the mandelbrot set where the functions exponent can be anything. If the exponent (third input field) is 2, you get the regular mandelbrot set.</p>
<a href="https://en.wikipedia.org/wiki/Multibrot_set">Wikipedia page</a>
<p>You can click to zoom and set the iteration count in the input field. The second input controls the exponent. This is quite slow to render.</p>

<h1>Fractals</h1>
<p>This page is a collection of fractals renderers I made in JS for a school assignment back in 2020. Please note that I don't use JS anymore.</p>
<h2>Fractal tree</h2>
<p>This is a fractal tree.</p>
<p>The tree splits into two parts, with an angle defined by the cursor's x positon. The number of iterations is defined by the first input field (which defaults to 12). Each branch is slightly smaller than its parent, as defined by the second input field. Click the canvas to freeze the image at any moment.</p>
<p>The splitting angle is defined by the mouses x position. The number of iterations is set in the first input field (default is 12). Each branch is slightly smaller than its parent, the factor is the second input field. Click the canvas to pause/resume the image.</p>

<h2>Mandelbrot</h2>
<p>The mandelbrot set is defined as the set of complex numbers for which a specific function (<i>F<sub>c</sub>(z) = z<sup>2</sup> + c</i>) stays within distance 2 from the origin when iterated from z=0.</p>
<h2>Mandelbrot set</h2>
<a href="https://en.wikipedia.org/wiki/Mandelbrot_set">Wikipedia page</a>
<p>You can click to zoom and set the iteration count in the input field.</p>

<h2>Multibrot set</h2>
<p>A multibrot set is a variant of the mandelbrot set where the functions exponent can be anything. If the exponent (third input field) is 2, you get the regular mandelbrot set.</p>
<a href="https://en.wikipedia.org/wiki/Multibrot_set">Wikipedia page</a>
<p>You can click to zoom and set the iteration count in the input field. The second input controls the exponent. This is quite slow to render.</p>
