graphene:point3d-equal (a b)

a -- a graphene:point3d-t instance
b -- a graphene:point3d-t instance

True, if the points have the same coordinates, otherwise false.

Checks whether two given points are equal. This function accounts for floating point fluctuations. If you want to control the fuzziness of the match, you can use the graphene:point3d-near function instead.
