![]() ![]() Can we give it four points, which the last two points are calculated from the previous two points and the line width, to form a line? According to the thought, we implement a prototype below. It accepts a list of coordinates to create a multiple sided shape. If you use the clockwise technique, you'll always have your faces outside (outside of OpenSCAD, other programs do use counter-clockwise as the outside though). Likewise, any other clockwise order of 4,0,5 works: 5,4,0 & 0,5,4 are good too. Next, calculate the length between two points, the angle between the line and x-axis, rotate the line and move it to the right position and so on. The winding order 0,4,5 is counter-clockwise and therefore bad. To review, open the file in an editor that reveals hidden Unicode characters. fibonaccigoldenspiral.scad This file contains bidirectional Unicode text that may be interpreted or compiled differently than what appears below. If it has two relatively short sides, the square looks like a line. Fibonaccis spiral in OpenScad using a simple polar equation Raw. Maybe the first thought which comes to your mind is that OpenSCAD has a built-in square module. The minimum task of the above requirement is connecting two points to form a line. ![]() Some better curated than others, some formatted for clarity some for efficiency. If you have to define a polyline module which accepts a list of points and connects all of them automatically, what do you have to solve first?ĭivide and conquer is an essential skill of programming. This is my notepad where i collect the useful snippets of OpenSCAD code that i use over and over. ![]() Why do you have to know the polygon module? After all, it's for creating a multi-sided shape, not for creating a line, right? Well, let's back to the topic. ![]()
