Hi there,
I have some curve geometries in my scene, with a LineBasicMaterial applied on them, but it seems that there is a clipping distance below which these objects disappear.
Is there an option in this LineBasicMaterial which I can modify to get rid of this problem? Does it depend on the geometry that uses the material (size/scale/position??)
Thanks for your help!

David

Hi David,
Can it be because of the camera clipping distance limits (which can be easily modified with Blender)? If not, can you share a simplistic example that reproduces this behavior?

Hi Alexander,
Thanks for your reply. I’ll try to put something in place but I’m afraid this is linked to my Application itself, and other things that happen in it, as I never saw this phenomenon in other “simplistic” apps where I made my tests and developments before to incorporate these in the main app…
I will first monitor these line material before and after the issue appears in the App, to see if something changed in the material that could explain it…

And about the camera clipping distance, I don’t understand how it could NOT see the line materials whereas it can see everything else… The camera clipping distance should affect everything am I right?

Solved! :)
It is due to the fact that I did not recalculate the bounding sphere of the curve objects when updating them…
So this is the line to add to the JS script:
curveToUpdate.geometry.computeBoundingSphere();
et voilà! :)
