I have CSV file with Vector3 values exported from a C# program. I would like to use vector operations (like calculating the distance etc.) in pandas. As far as I have seen, there is no Vector3 type in pandas. np.array offers this kind of operations but it is not available in pandas. What is the easiest way to…

Why is a hg.Vec3() vector passed to a Python function modified by it?
I’m working on a 3D project in Python using the HARFANG 3D wheel (I got from Pypi). I have a function where I pass a series of data, including a vector3: I don’t return position and it is not a global variable. However, when returning from this function, position is modified within the scope of th…

Generating N random unit vectors with their sum equal to 0 (Python)
I’d like to generate N random 3-dimensional vectors (uniformly) on the unit sphere but with the condition, that their sum is equal to 0. My attempt was to generate N/2 random unit vectors, while the other are just the same vectors with a minus sign. The problem is, as I’m trying to achieve as litt…
Integer overflow while calculating all possible sums of n*m matrix rows
I am using this code to compute all possible sum of a n x m matrix. The code is working absolutely fine and it is fast too when using arrays of 32-bit integers like [[777,675,888],[768,777,698]]. It is using the Numpy package. However, as soon as I use 128-bit integers or bigger, I start getting negative valu…
