Library is a port of my C library: https://github.com/monolifed/vmath (Unlicense)

IQM animation demo is modified to use this library (replacing cpml)

Nice. It seems to have alot of stuff, that's good!

It's nice that this library uses numeric components instead of letters, and flat matrices instead of two-dimensional. Also nice that it returns values via modifying an argument. I've made work on a library that works this way, but the unit tests were too boring to write.

Typo:

Code: Select all

function quat.from_rot(r, v, a)
	a = a / 2
	local s = sin(a) / sqrt(v[1]^2 + v[2]^2 + v[3]^2)
	r[1] = s * v[1]; r[2] = s * v[2]; r[3] = s * v[2]

Pay attention to r[3].

Thanks, there must be more typos and mistakes
It should have been function quat.from_rot(r, a, x, y, z) like (mat4.rv etc) to begin with
