warp.sample_unit_disk

warp.sample_unit_disk(state: uint32) → vec2f

Kernel

Python

Uniformly sample a point inside the unit disk (radius <= 1) in the xy-plane.

Returns a vec2. 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()).
