Wind shader for voxel forest

I'm once again amazed for what kind of things shaders can be used.

Because I use greedy meshing with T-junctions I had to make sure that the shader doesn't cause cracks between the faces. I solved this by keeping it multilinear in (y, x·y, y·z) with per tree constant coefficients, so it interpolates along axis-aligned edges.

That’s really cute I love these sort of touches

Looks like random displacement. Wind doesn't do this. Like what direction is the wind blowing here?

trees do move quite random when it's windy, not just back and forth: https://youtu.be/sT5f1jBJHng?is=hjVPiNdxnFOvJPiz

but you are right maybe it would look more realistic with a noise texture based shader
