point in volume

[clankill3r]

How can i get this point in volume to work?
I want to know which points of the small sphere are in the big sphere.
(the ice tree is on the big sphere)

Get rid of the Switch Context and plug small_sphere.PointPosition directly into Point in Volume. Then save the attribute as small_sphere.tmp instead of self.tmp.

thanks, up to the next problem

i did this tutorial by paul smiths (awsome tutorial btw),
https://vimeo.com/19034079

basicly you can punch a object in another object and it leaves a dent.
It looks at the closest location for that.
However when the object moves in to deep at once then it can be that the closest position is not inside the original shape but outside of it.

To prevend that i want first to see what points are inside the shape and then choose either one of those points instead of any point of the object.

here i check for which points of the sphere are in the big sphere (called globe), as you can see that works fine.


From the points of the globe that hit the small sphere, i want to bring those points to a position shown in the first image.
I have this, which must work i think but it doesn't...


This is what i get when i disconnect "find closest in array" and the "if true".

It should get one of the vectors i stored in sphere.insideGlobe right?

Find closest location in the inverse direction of the point normals. Probably use a raycast node instead so you can set the direction which would be [Get Point Normal] > [Multiply by Scalar: -1] > [Direction]

thanks, works like a champ.
Still i wonder why the above thing didn't work.

If condition return true for points inside of a sphere. "If True" port has 0,0,0 vector value by default, those points were moved to global center.

that's for the image where i broke the connection line.
What about the one where it reads the vectors from the other object? (2nd image)

PointPosition is an per point attribute, it's not an array. You shouldn't change the context for arrays also. See this: Getting and setting data–understand data context, structure, and type
