This Bifrost compound that can compare geometry and show how and where they differ.
Autodesk’s Roland Reyer explains how to use the CompareGeometry compound in Maya 2019 that uses Bifrost 2. The compound lets you see at a glance, where two geometries differ. The compare geometry compound node takes two geometries as inputs and outputs them as a color.
The output color can show where the two objects differ at a glance. What’s interesting is that the compare compound works in realtime with objects up to 300k polygons. You can download the compare geo compound from Autodesk’s Bifrost repository.
