11/13/2024, 8:08 PMHey, I'm a little confused when it comes to Kotlin math libs. I'm looking for a good library to use for 3D graphics (matrix multiplications etc). There is kmath by romain guy, multik by Kotlin itself, korlibs-math, and some others. So which one fits best?

KMath is much larger framework, that integrates a lot of mathematical tools such as matrix decomposition, integration, optimization etc. Korlibs is very limited, it is design mostly to support Korge and 2D graphics.

I'm hoping for proper Kotlin value classes soon so we won't have to painfully pay an object allocation for each small vector/matrix.
