In Blender Python test for a clear path between 2 points

clearPath.py

def isClearPath(vert1, vert2, depsgraph):
    # Test if there are any obstructions from vert 1 to vert 2 until it reaches obj2
    # test for given clearance around the ray traced path with 6 parallel line a given distance of clearnace away from original path t test fo
    # isClear = isClearPath(vert1, vert2, depsgraph)
    
    # Calculate the direction vector from vert1 to vert2
    direction_vector = vert2 - vert1
    
    # Normalize the direction vector
    direction = direction_vector.normalized()
    
    # Calculate the distance between vert1 and vert2, subtracting the offset
    distance = direction_vector.length
    
    # Apply the offset to avoid self-intersection with vert1
    start_point = vert1 + direction
    
    result, location, normal, index, object, matrix = custom_ray_cast(bpy.context.scene, depsgraph, start_point, direction, 0.1, 5, distance=distance)
    #result, location, normal, index, object, matrix = bpy.context.scene.ray_cast(depsgraph, start_point, direction, distance=distance)
        
    # If any of the rays hit an object other than obj2, return False
    if location != vert2:
        return False
    # If all rays hit obj2 or didn't hit any objects, return True
    return True
