Note: most of these demos use D3 to keep the code concise, but this can be used with any library, or with no library at all. If single is set to true this returns one interpolator that combines things into one giant path string or one big array of rings.įlubber. If single is false, this returns an array of n interpolator functions, where n is the length of toShapeList. The options are the same as for interpolate(), with the additional option of single, which defaults to false. This isn’t terribly performant and has some quirks but it tends to get the job done.įromShape should be a ring or SVG path string, and toShapeList should be an array of them. If you’re trying to interpolate between a single shape and multiple shapes (for example, a group of three circles turning into a single big circle), this method will break your shapes into pieces so you can animate between the two sets. toRect() in action omCircle(x, y, r, toShape) toRect ( triangle, 10, 50, 100, 200 ) interpolator ( 0 ) // returns an SVG triangle path string interpolator ( 0.5 ) // returns something halfway between the triangle and the rectangle interpolator ( 1 ) // returns a rectangle path string from in the upper left to in the lower right
