maya bend deformer algorithm

[Michał Frątczak]

Hi

I need to recreate maya's bend deformer as a custom tool.

Does anybody have working code ?

thanks !

You try linearBend deformer before ?

I'm not sure what you mean ?

This should get you there:
https://github.com/BigRoy/maya-matrix-deformers/blob/master/matrix_deform/nodes/matrixBend.py

Note that this is also calculating an actual rotational value along with it which isn't needed if you're doing pure point/vertex deformation.

Why do you need a custom implementation? :)

What I need to do is hundreds of words orbiting around common center
axis (cylindryically).
I want to create animation with particles and instancing and bend words
with displacement shader.

Is this for learning purposes, or production? You can technically achieve that with the regular bend deformer in Maya, and if that’s not enough, you could also create a joint chain per vertex (or even approximately) and simply rotate them all along one axis, and if that’s not enough you could also bend-deform or joint deform a regular poly cylinder (or even a plane), and wrap deform your text to that.

This is for production.
Particles give a nice procedural approach, where I can easily control spacing, speed and most important: number of words.
If this fails I'll fallback to deformers, but that's not iteration friendly path :)
