[Algorithms] Quick question (random dispersion)

[Oles <ol...@gs...>]

Hi.

Given unit direction vector, we need to deviate it by some amount
of degrees.

My current method is dummy: generate point on capped side of
"identity" cone and xform it by matrix builded from original vector.

Can u suggest correct (and probably faster) approach?

Thanx.
