//Spiral Notes
|
||
//-------------------------------------------------------------------
|
||
//Height = center to center height of the end spheres which form the spirals. Ends will need to be flattened by the user as desired. Actual height of the rendering is Height+2*baseRadius
|
||
//Radius = the maximum distance from the axis of the spiral (the z axis) to the center of the sphere(s) forming the spiral
|
||
//baseRadius = cross sectional radius of the spiral
|
||
//frequency = the number of complete revolutions about the axis made by the spiral, whole numbers will result in spirals whose tops end directly above their bases
|
||
//resolution = integer number of spheres, not to be confused with $fn. The greater the number of spheres, the smoother the spiral will be (also longer render times!). Recommended that this number be 8*frequency or greater.
|
||
//numSpirals = integer number of spirals used in the spiralMulti modules spaced evenly around the axis (3 spirals are spaced 120 degrees apart, 4 spirals: 90 degrees apart, etc.)
|
||
|
||
//Instructions
|
||
//------------------------------------------------------------------
|
||
//1. Place spiral.scad in the "libraries" folder of your openscad installation. Find the libraries folder by File -> Show Library Folder...
|
||
//2. Then create a new or open one of your existing scad files and include spiral.scad with the following code:
|
||
//use<spiral.scad>;
|
||
//3. Then call the modules in your files with code similar to the following:
|
||
//spiral(20,20,3,1,25);
|
||
//spiralCone(20,20,3,1,25);
|
||
//spiralEllipse(20,20,3,1,25);
|
||
//spiralMulti(20,20,3,1,25,3);
|
||
//spiralMultiCone(20,20,3,1,25,3);
|
||
//spiralMultiEllipse(40,60,3,1,32,3);
