Re: [OpenSCAD] Wanted: rotate function on vectors
Sun, Jan 25, 2015 7:51 AM
[[1,0,0],[0,cos(a[0]),-sin(a[0])],[0,sin(a[0]),cos(a[0])]] *
[[cos(a[1]),0,sin(a[1])],[0,1,0],[-sin(a[1]),0,cos(a[1])]] *
[[cos(a[2]),-sin(a[2]),0],[sin(a[2]),cos(a[2]),0],[0,0,1]] : cos(a)*identity
+ sin(a)*unit_vector(v) + cross((1 - cos(a))*unit_vector(v),
unit_vector(v));
To do this on a list of vectors, you'd use a for loop

Path sweep
Sat, Mar 2, 2024 8:50 PM
function(x) 1262.6651 - 1.81977 * y(x),
d = function(q) sqrt(q * 4 / sqrt(3)))
sweep(path = function(t) [t2x(t), 0, y(t2x(t))],
scale = function(t) d(Q(t2x(t))),
angle = function(t) 120,
$fn = 100)
circle(sqrt(3) / 3, $fn = 3); // unit-side triangle
The way Fusion 360 does it might be better.

Re: [time-nuts] Frequency subtraction with D-flip flops
Tue, Jun 25, 2013 7:15 AM
I must say
all my experience is with fc very close to fd in frequency, so maybe I am
missing something about the fd>>fc case.
Cheers,
