Bifrost Visual Programming Master Class

hello marcus,i saw both videos i think the amount of information u shared is most valuable ever since the release of bifrost.however i have few questions? it possible to cluster sum of the faces together instead of breaking every individual face. thing i often see is bifrost heavily relied on arrays compared to houdini which is more relied on it gng to change in future?

About your second point, arrays and "attributes" (in Bifrost, we call these properties) are often the same thing so I am not sure exactly what your question is about. Could you clarify?

> it possible to cluster sum of the faces together instead of breaking every individual face.


The whole action depends on *faces* as identifiable parts of the surface. For each *face* you can find the points and move/rotate/scale them.


If you want larger pieces (a bunch of faces) then you need to identify them so that you can use ONE center for move/rotate/scale.

This is technically possible.

@marcus.nordenstam could you quickly do this for us?


A simple way would be to break up the geometry in Maya (Extract all faces with "Keep Faces together"=OFF, then sew some together with Merge Vertexes) and then simulate this object as cloth 🙂

(EDIT: doesn't work in Bifrost. The MPM sover merges the pieces together. Works in nCloth though ;-P)

I am going to hop on this thread and ask a question regarding this tutorial also.  We have the most recent BiFrost installed but I am not finding the "flatten_array" node so am stuck at this step.  Trying to create my own set of nodes to replicate the behaviour but having no luck yet.  It would be great to have an easy way of querying values at nodes along the graph to be able to debug easily.

Figured it out.  Its part of the Rebel pack.
