sptnk/math/rot 3d k
Geometric rotations for 2d and 3d coordinates.. Useful for lissajous applications.
Based on this: https://en.wikipedia.org/wiki/Rotation_matrix
Some k-rate mappings. You can see the meaning of parameters in the pictures. m stands for angular coefficient (in y = mx + q)
Not sure if they should go in the math folder... Again, they're for lissajous purposes. These objects will generate a set of coordinates (with pitch) to form a grid with R rows and N columns.
Available in k-rate and s-rate
