VecMath.intersects() returns false, but line segments do cross

VecMath.intersects(309, 262, 311, 269, 314, 266, 295, 266);

 

returns false. Why?

 

thx

Re: VecMath.intersects() returns false, but line segments do cross

I just wrote a quick function that did the math and it returned true so you might want to put it in Issue Tracker so it gets resolved.

Thx.

 

I found a workaround meanwhile, I assume

 

VecMath.intersects(ax0, ay0, ax1, ay1, bx0, by0, bx1, by1) ||
VecMath.intersects(bx0, by0, bx1, by1, ax0, ay0, ax1, ay1);

will do the job.
