Apply Transform ( Translate + Rotate + Scale ) to mesh

[atazangene]

I am using Nvidia omniverse and I want to integrate the Meshlib into it, I want to apply transform ( translate + rotate + scale ) into a mesh

actually the transform data stored into Gf.Matrix4d in the omniverse code :

Matrix4D Doc

Now, I want to apply that to mesh inside the meshlib. we have a sample on how to apply translation on meshlib, but there is no example of on how to apply scale and rotate on meshlib SDK python.

Meshlib SDK doc - boolean operation

can you help me on this please?

Hello!

Is it what you mean? #4530

We also have

from meshlib import mrmeshpy as mm
mat4 = mm.Matrix4f()
xf = mm.AffineXf3f(mat4)
# Or in older Python bindings:
# xf = mat4._convert_to_AffineXf3_float()
...
mesh.transform( xf )
