 			<h1>8. Metaballs</h1>
+			<p>Using CPU marching cubes to create metaballs, and similar to <a href="../6">Wobbly Earth</a>, using a Custom Standard material, this time to also modify the fragment shader, and add a striped procedural texture to the metaballs, and modify the normal to add some bump across the alternating lines.</p>

-				<p>Using <b>ShaderTexture</b> to create a diffuse texture (using <a href="https://www.shadertoy.com/view/4st3R7" >TruchetFlip</a>'s implementation of <a href="https://en.wikipedia.org/wiki/Wang_tile">Wang Tiles</a>) and a roughness texture (using the diffuse texture to modulate some noise), then again using the diffuse texture as a height map to turn it into a normal map (using a shader based on <a href="http://cpetry.github.io/NormalMap-Online/" >NormalMap Online</a>).</p>
-				<p>The maps are then used as diffuse, roughness, metalness, bump and normal maps of a THREE.MeshStandardMaterial.</p>
+				<p>The fragment shader computes a color based on the y position of the fragment, and calculates the discontinuities between lines, perturbing the normal accordingly.</p>
+				<p>The rest is all marching cubes and MeshStandardMaterial.</p>
