The Cornu spiral is a plot in the complex plane of the points B(t)=S(t)+iC(t), (1) where S(t) and C(t) are the Fresnel integrals (von Seggern 2007, p. 210; Gray 1997, p. 65). The Cornu spiral is also known as the clothoid or Euler's spiral. It was probably first studied by Johann Bernoulli around 1696 (Bernoulli 1967, pp. 1084-1086). A Cornu spiral describes diffraction from the edge of a half-plane. The quantities C(t)/S(t) and S(t)/C(t) are plotted above. The slope of the curve's...

Over the last couple of weeks I started to learn Houdini, partly from tutorials by Entagma and others, partially by implementing things I worked on in Grasshopper for Rhino (which is single threaded and rather slow for larger assets) over into the Houdini world. This one started out from the Enta...

A helix, sometimes also called a coil, is a curve for which the tangent makes a constant angle with a fixed line. The shortest path between two points on a cylinder (one not directly above the other) is a fractional turn of a helix, as can be seen by cutting the cylinder along one of its sides, flattening it out, and noting that a straight line connecting the points becomes helical upon re-wrapping (Steinhaus 1999, p. 229). It is for this reason that squirrels chasing one another up and...

Jarrod Hasenjäger discussed his approach to creating realistic and stylized art in MODO, shared his workflow with both styles and talked about combining MODO and Arnold.

Various transition curves are used in civil engineering to gradually introduce curvature and superelevation between both tangents and circular curves as well as between two circular curves with different curvature.

How do you create a sphere made of all quads; Polygon Mesh has poles and polygon is triangles ? I want a sphere without any poles; but all quads.

I was wondering if there is a way of combining two primitives e.g. two 2D circles that get into a certain range of each other like in the gif below. I was taking a shot at it myself but so far it's too dependent on point numbers and orders. combining_circles.hipnc
