Is there a way to fill a geometry with another one, without penetration?

Hi;

Is there a way to fill geometry with another one, without penetration?

 

Thanks for helping.

Hi Masoud,

you can fill meshes with other meshes by copying them to VDB to spheres. Make sure to center and scale the copy mesh beforehand so it fits into a unit sphere.

// center object
vector center = getbbox_center(0);
v@P -= center;

// maximum distance from center
float dist = length(v@P);
setdetailattrib(1, 'max_dist', dist, 'max');

// scale maximum distance to 1 
float scale = detail(0, 'max_dist', 0);
v@P *= 1.0 / scale;

Hi "Konstantin";

Your solution is great, but it uses a spherical boundary to separate objects, right?

Actually, I'm looking for a way to fill an object more precisely, without a big gap between them, something like the image below:

(The object in this sample scene is generated using Cinema4D.)

 

Thanks.
