# trimesh.interval¶

## interval.py¶

Deal with 1D intervals which are defined by:

[start position, end position]

Functions:

 `check`(a, b, digits) Check input ranges, convert them to vector form, and get a fixed precision integer version of them. `intersection`(a, b[, digits]) Given a pair of ranges, merge them in to one range if they overlap at all
`trimesh.interval.``check`(a, b, digits)

Check input ranges, convert them to vector form, and get a fixed precision integer version of them.

Parameters
• a ((2, ) or (2, n) float) – Start and end of a 1D interval

• b ((2, ) or (2, n) float) – Start and end of a 1D interval

• digits (int) – How many digits to consider

Returns

• a ((2, n) float) – Ranges as vector

• b ((2, n) float) – Ranges as vector

• a_int ((2, n) int64) – Ranges rounded to digits, as vector

• b_int ((2, n) int64) – Ranges rounded to digits, as vector

• is_1D (bool) – If True, input was single pair of ranges

`trimesh.interval.``intersection`(a, b, digits=8)

Given a pair of ranges, merge them in to one range if they overlap at all

Parameters
• a ((2, ) float) – Start and end of a 1D interval

• b ((2, ) float) – Start and end of a 1D interval

• digits (int) – How many digits to consider

Returns

• intersects (bool or (n,) bool) – Indicates if the ranges overlap at all

• new_range ((2, ) or (2, 2) float) – The unioned range from the two inputs, or both of the original ranges if not overlapping
