Is it possible to uniformly draw points over a $D-1$ dimensional2$ sphere, given that one has an algorithm to draw over the $D$ dimensional$D-1$ sphere in D-dimensional space?

in comments OP stated that a circle was meant not a disk as in original language

Is it possible to uniformly draw points over a $D-1$ dimensional disksphere, given that one has an algorithm to draw over the $D$ dimensional sphere?

Suppose I have the following scenario:

enter image description here

And I am aware of an algorithm to draw uniformly from (in this case) the 2-sphere. Does this same algorithm readily extend to the situation where I randomly take a "cut/slice" (shown in red above) and what points uniformly over this diskcircle?

Further, suppose now that I have a uniform random sampling algorithm over an arbitrary Riemannian manifold. Would the same principles necessarily apply?
