Hi David,

Thank you. I miss understand the definition. I thought it was the origin and the end point. Thanks a lot.

Best,

Hi David,

Thanks a lot for this great tool. I am using the intersectLinePolygon3d function. Some of the results seem not make sense. For example:

pts3d = [-1 -1 5;1 -1 5;1 1 5];
line=[0.6 0 0 0.6 0 10];
[inter inside] = intersectLinePolygon3d(line, pts3d);

And I got:
nter =

0.9000 0 5.0000

inside =

1

Should we expect to get inter = 0.6 0 5?

Thanks so much,
Haochen
