"Evaluate Curve" node outputs weird FreeCAD tangents values #3652
Comments
I suspect they are just not normalized... |
You seem right, because the direction looks the same, although after a normalize the values didn't change (weird?) The other thing I found is with the Curvature and Torsion values. Again FreeCAD differs from other implementations. Here's the file: |
Also normals and binormals have slight differences at T=0.0 and T=1.0 Test file updated: |
A small off-topic: |
Just checked the test file I did, and none of the above issues are solved. @portnov can you check that? |
A small update here. Still no clue why curvature and torsion are so different. |
Closing this issue and opened one for Curve Curvature #3804 |
FreeCAD curve tangents output differs from SV and Geomdl
This is the test file I'm using:
