The Moth must exist in different forms for different purposes.
Here I am attempting to create a stylized, if relatively realistic version
primarily for 3D printing. As part of the process I'm continuing work
on TREEjs, an update to Turbine which will be more flexible.
This code creates the two wings and the body of the moth that you see here.
tree = new TREE();
//upper wing
tree.generate({
joints: [4,30],
divs: [0,1],
start: [0,0],
angles: [0,Math.PI/2],
length: [2,5],
rads: [1,1],
});
xform(makeInfo([
//rotate root
[0,0,"all"], {rz:-.12,sc:1},
[0,0,0], {ry:.2,rz:.3,sc:1},
//bottom joint
[0,0,0,0,0], {rz:2,sc:1},
[0,0,0,0,[1,15]], {rz:-.05,sc:1},
//second from bottom
[0,0,1,0,0], {rz:1.8,sc:1},
[0,0,1,0,[1,20]], {rz:-.02,sc:1},
//top
