Confused about forces and specification POP

When using points as a specification POP for the forceradial POP, I encountered unexpected behavior.

Using the Op-Snippet for forceradial the example makes sense when using the radial force and the spec pop. When visualizing the length of the forces, as in the example, we can make out the forces at the points locations.

But when I change the force type, (spiral, planar, axial) the forces no longer seem to be connected to a point with a xy radius, but rather a single axis.

Can someone explain this?

Hello @electro666,

The other force types are using both the position and direction, in the above since the direction is 0,1,0 and you’re looking at a XY plane it’s harder to see the effect of position.

If you switch the direction to 0,0,1 for example you’ll see better the effect of position.

The direction can also be overriden per point if you add a direction attribute to the point POP used for specification.

Let me know if that makes sense!

Thanks that clears it up, I thought direction designated the up direction since it defaulted to +Y.
