mathematical arc for openSCAD

thingiverse

This module operates within a trigonometric framework, utilizing the counterclockwise rotation of the x-axis as its reference point. A crucial consideration is that the start value should always be less than the end value to ensure accurate calculations. In version 2, I implemented a check for these values to prevent potential issues during computation. The processing of angles has been optimized and the number of polygons drawn to represent the circle has been reduced. This module can be seamlessly integrated into your project or library as needed. The incoming angles are verified to determine if conversion is necessary to align with the trigonometric circle's functionality. The opening angle is then divided into a minimum of 45-degree increments, ensuring precise calculations. Each triangle's height is calculated to exceed the outer circle's radius, guaranteeing accurate representation. A loop efficiently draws the triangles from the start value to the end value within the defined scope, with each triangle overlapping by a minimum of 2 degrees – the threshold for effective treatment.
