Caterpillar
If we can make 2-D art out of nothing but dots on the paper, it seems we should be able to make 3-D objects out of nothing but spheres. And we now can in Madeup. I added a dot command, such that a sphere is placed at every point the programmer visits with a move command. My test run was to build a caterpillar:
A caterpillar composed of a sine wave of dots.
On my TODO list: iterate along the wave so that the samples are evenly spaced. This requires a visit back to the lessons of calculus.
The code that produced this fellow is:
nsides = 50
delta = 20.0
radius = 20
theta = 0
amplitude = 70
-- Body
while theta <= 360
moveto theta (amplitude * (sin theta)) 0
theta = theta + delta
end
-- Eyes
radius = 10
moveto 0 10 -15
moveto 0 -10 -15
