blending two meshes with different noise

[arjun]

Hi

• I have 2 meshes with different topology and different frequency of noise on it
  
• I also have some deformation on both the mesh
  

Is it possible to project and blend the details of 1 mesh on to the other

[Hello world]

level sets?

post your file

it's possible with geometry but you need to be able to project one onto another at some frame or at rest position, simply they cannot be too different in shape like torus and sphere, since the process would be essentially deforming one into another without retopologizing

otherwise SDFs are better option as vig suggested, but you will loose details and it's slower and memory consuming

i tried using the ray sop in geometry level but the result was not that great can some explain little bit

more on how to use levelsets

I didn't mean ray sop

basically you can use ray sop as initial pass to get the closest position on surface of second aligned mesh

then in use Intersect VOP to ray towards that position and store primnum and u,v from hits as point attribute

then in another vop sop just read actual position from second geo using primnum and u,v (Primitive Attribute VOP)

and you can freely blend between 2 animated meshes with different topology

I will make some example when I'm free

for levelsets

it might work the best if your objects are on top of another

create SDF from both with isooffset SOP with the same resolution and override bounds to the same bbox as well to avoid unnecessary interpolation

then you can just use BlendShapes SOP or SequenceBlend SOP with Blend Voxel Data checked to blend between them
