solved LineMesh not showing if endpoint off camera

[Kreeba]

I have some line meshes that are just 2 vectors, one at the start and the other for the end. These lines then update every pre-render as they are between two objects that move.

I have noticed that when the end vector position is out of view of the camera then the line doesn't show.

Is this normal behaviour? How can I correct it so that the lines always render no matter if the end point is out of view or not?

 

Thanks

Hi K!  That sounds... non-normal.  hmm.  Can you make a playground that shows us the problem?

Here's a  playground that has lines connecting moving mesh.  Maybe it will help fix something.

It seems to keep drawing lines okay, even when control-dragging the camera until one of the mesh is out-of-view.

Maybe you can borrow a little code from there.  Good luck, report back.  thx.

The line won't be rendered if the bounding box of the line goes off camera.

For example:

line 58 : refreshBoundingInfo()

mmmh.. something I could embed in the call to the morph update

or set

linesMesh.alwaysSelectAsActiveMesh = true;

or set a larger bounding box from the start.

Thanks that has got it. Marked as solved
