Recently, i use the `Convexhull.h` to submit problem 2195 on CSES. It passed almost of tests, except one test:
```
4
3 2
1 5
3 6
3 5
```
the judge returned error:
```
code: malloc.c:2617:…

`convexhull` [strips the points buffer](https://github.com/jimy-byerley/pymadcad/blob/99521a48271e095eb1e07195feac75e08533328e/madcad/hull.py#L42), not sure this is necessary anymore

Here is an example, related to CLS Example 6.1.11:
```m2
needsPackage "NormalToricVarieties"
N = ZZ^3;
P = convexHull matrix {0_N, N_0, N_1, N_0 + N_1 + 2*N_2};
X = normalToricVariety P
D = 2*X_…

the Convex Hull from [3D ImageJ Suite](https://imagej.net/3D_ImageJ_Suite) does the job but it's so slow!!!
We usually downscale 2 to 8 times (which means we also lose precision).
Is there a way t…

https://juliaimages.org/latest/api_comparison states that `convexhull` is the API equivalent to MATLAB's `bwconvhull`, but it actually returns the outer points of the convexhull and not a "filled in" …

Hi, I had this problem while using KMeansLayer:
_raise Exception('convexhull requires at least 3 points')_
how can I use it?
ps: my data file is a txt file, and it has three columns (id, lon, lat…

There are various performance optimizations that can be made in the ConvexHull algorithm.

Hi @perezjln
Thanks for the great work!
Currently I am using the standard installation script provided in README but some how cannot run the sample code:
```python

Calling `Polyhedron::ConvexHull` will sometimes cause a segmentation fault. I've attached a sample point cloud for which this will occur, as well as a rendering of the points.
