Probably a bit premature but the code is just unmaintainable. This will allow/force me to focus on format 4.

Actually, I wonder if it should be Pointcloud and PointcloudMaterial instead (lowercase c)?

ShaderUtils relied on ShaderChunks so this created troubles when trying to use three-canvas and three-extras. Besides, better to keep a single library of shaders.

THREE.Path
THREE.Shape
THREE.CurvePath
THREE.Curve
THREE.SubdivisionModifier
THREE.ExtrudeGeometry

@sole you might be interested in the script i used to help generate this.

p = new THREE.Path()
for (i in p) {
p.hasOwnProperty(i) && console.log('\n<h3>.' + i + '</h3>');
}

console.log('-------------')

for (i in p) {
var pp = p[i].toString().replace(/function/,'');
THREE.Path.prototype.hasOwnProperty(i) &&
console.log('\n<h3>.' + i + pp.substring(0, pp.indexOf('{')-1).replace(/\s+/g, ' ')  + '</h3>\n<div>todo</div>' );
}
