[Community] how can I define ray line in shapely?

[KIA]

hi
i have some code in python and i use shapely module in that
I need to define ray line with specific origin and angle to intersect
with some other shape
but shapely module does not have any object like ray line
I have tried to use ray object from sympy module but I cant intersect
sympy object with shape object...
could you please give me an idea about how can I define ray line with
specific origin and angle with shapely?...
thank you so much in advance

To be clear, you want to find the intersection of any geometric object with
a ray that has an origin and an angle?

Yes, that is true

There is no ray object in Shapely. You could approximate one in the context
of a given geometric object target like this:

1. Determine the bounds of the target (target.bounds)
2. Using your ray origin and angle, find a point along the angle that is on
the other side of the target bounds from the origin
3. Combine that with the origin to make a line

Of course, if the origin is within the target you will have to extend the
line in both directions.
