warp.sample_unit_ring

warp.sample_unit_ring(state: uint32) → vec2f

Kernel

Python

Uniformly sample a point on the unit circle (radius 1) in the xy-plane.

Returns a vec2 of unit length. In a kernel, advances state in place; called from the Python scope, it does not modify state, so repeated calls with the same state return the same point (see rand_init()).
