volume of an object affect on your effect

[amin.khormaei]

hey guys ,

how can I calculate the volume of an object in VEX ,

I want to write something like this one below:

the line of your script * volume of a specific object

I used getbbox_size but the result is a scalar.

I want everything in the object to have the effect.

what should I do?

best regards

you can use Measure SOP to get volume of a polygonal geo per piece for example or for the whole detail

as long as it's manifold, watertight and geometry normals point outside the volume value should be correct

then you can use it in your wrangle

thank you ' i'll try that

[amin.khormaei]

how can I import an attribute to wrangle from it's second input?

[amin.khormaei]

this is the file , I tried several things :

detailintrinsic , primintrinsic , totalvolume

but I couldn't solve that

Vex.hip

you can use detail() function for example

detail(1, "totalvolume");

[amin.khormaei]

I tested that , it didn't work, could you modify my file and upload that?

thank you so much, but you didn't get me.

I want this effect (the wave) to occur inside the sphere, and outside the sphere nothing happens.

the sphere act like an effector in cinema4D.

oh, that was not clear at all, in that case you can use Distance From Geometry node for example, that will give you also some falloff
