Visibility.OfLinesFromOrigin not considering correct obstructions

[paoloemilioserra]

Passing the center of the desk as origins, the lines for the windows, the polygon for the boundary, the desks as obstructions.

[paoloemilioserra]

Ignoring the obstructions I get this (in red the only one I'm expecting to see with obstructions).

Instead I get nothing

Thanks @paoloemilioserra ! Would you be able to share the script/dataset or just this part of it?

Hi @paoloemilioserra

Can't seem to reproduce this, could you share the dataset or can I close this?

[paoloemilioserra]

@SHKnudsen I can't share the file but the issue appears to be in a "polyline branching" error thrown in the node that returns null

[radumg]

Thanks @paoloemilioserra , @SHKnudsen is trying to reproduce the error, any dataset or further screenshots of the graph just before that node would be very helpful.

The polyline branching error is a LiBG error.

hey @paoloemilioserra , any chance we can get some data to help us replicate this ? Would like to fix these open bugs in Q4. Happy to do a Zoom call if it's easier ?

I cannot reproduce this error. This graph demonstrates it working as expected. What may have happened to @paoloemilioserra and something I found was, that I was patching the view cones incorrectly at first.

Actually, I might've spoken too soon. The above example at 0.275 for the input does reproduce this.
