ALGORITHMIC SKETCHBOOK
week 1 Lofting curves: Four curves set as inputs into simple loft algorithm. Progression from planar surface to undulating form achieved through simple transformations on input curves and curve control points. The model updates instaneously as the input curves are manipulated which is handy for quickly producing a progression of iterations.
Triangulation algorithms: 1. Delaunay mesh 2.Voronoi 3. OcTree - approximates complex geometry by fitting boxes to it. Each of these techniques can be used to ready a form for production by generating more easily fabricated geometries (i.e. meshes). Additionally they demonstrate how a degree of formal complexity may be generated within Grasshopper using only 2-3 step algorithms.

Range A domain is a space defined by a minimum and a maximum (e.g. 0<x<1). The range component divides this domain into a number of segments (e.g. 10 segments). The points generated are represented by coordinates, most likely cartesian in nature (existing in xyz space). These points can be then used to generate more complex geometric types such as a sine or cosine curve, or a combination of both (pictured).
Point Polar Point Polar component requires radian (i.e. non-cartesian) inputs, in this case using pi. Two spirals are generated, indentical albeit one has a z-input. The surface is generated by a simple loft of the lines between these two spirals.
