hello @KevinKarney, welcome to DrawBot!
1. I need the option to build compound objects (with unions, differences, intersections). Is it possible to make (e.g) a torus by differencing 2 circles. Or do I have to create two bezier paths and then do the difference.
both methods are possible:
you can do it with a single BezierPath by drawing two circles in opposing directions:
x, y = 500, 500
r1 = 400
r2 = 300
B = BezierPath()
B.oval(x-r1, y-r1, r1*2, r1*2)
B.reverse()
B.oval(x-r2, y-r2, r2*2, r2*2)
fill(0, 1, 0)
stroke(1, 0, 0)
strokeWidth(10)
drawPath(B)
or you can draw two separate circles, and get the difference between them:
B1 = BezierPath()
B1.oval(x-r1, y-r1, r1*2, r1*2)
B2 = BezierPath()
B2.oval(x-r2, y-r2, r2*2, r2*2)
B3 = B1.difference(B2)
drawPath(B3)
2. with primitives such as oval or rect, can I incorporate the fill, stroke, strokewidth, etc into the call.
In Nodebox 1, I can say (e.g)
a = rect(0,0,20,20,stroke=Red,strokewidth=3,fill=Grey, draw=False)
This creates an object call a, but does not draw it....
grouping colors and geometry can be done with functions:
def a():
stroke(1, 0, 0)
strokeWidth(3)
fill(0.5)
rect(0, 0, 20, 20)
a()
hope this helps… have fun with the movies, and let us know if you have any other questions.
