vertical flow velocity with an angular velocity for rotational flow around the up vector #3
Description
In flow.js , if the velocity variable is modified with:
'vec3 velocity = vec3(' + Math.cos(angleRadians) * baseSpeed + ',' + Math.sin(angleRadians) * baseSpeed + ', 0.0);',
The flow becomes vertical. But I am frustrated trying to adjust the code to have a helical azimuthal flow. Maybe I can get some help with that?
