This generates a point cloud of uniformly distributed points inside a bounding box.

This version of the Rebel Pack, 0.2.2, works with Bifrost 2.0.2.0 and later versions. New in 0.2.2 New, less red icon small_slice – a new compund that creates a small slice of an array in way that's faster for small slices set_mesh_uvs is fixed update_point_neighbors is faster update_strand_basis is faster What is the Rebel Pack? The product team of Bifrost often make compounds for our own use, and these sometimes make it into the compounds Bifrost ships with. Quite a few of the compounds that ship with Bifrost today started here. These compounds are distributed together in a "pack", where some compounds use and rely on other compounds in a pack. The compounds included include math utilities, property access nodes, and nodes for manipulating strands, meshes, as well as some simulation caching utilities.  In the graph these are all marked with a orange "R" icon as their names and namespaces are integrated into the existing ones. Ones with an orange test tube are especially experimental - we expect them to change.  These are not officially supported like the compounds that ship with Bifrost, but we have been maintaining these and intend to continue to do so. We will also specify which versions of Bifrost these nodes are intended to work with. This is also a way for us, the product team of Bifrost, to act as if we're TDs at a studio maintaining our own set of compounds, which makes our testing a bit more like the real world.  For information on how to install compounds and graphs, please see the documentation: http://help.autodesk.com/view/BIFROST/ENU/?guid=Bifrost_Common_install_compounds_and_graphs_html

This compound will take a source and target objects (with the same vertex count and same vertex order) and will create a new source mesh where the colors are the result of the difference in (local) vertex positions between the two given meshes. This is useful for detecting deltas between a neutral mesh and its blendshapes. The sample scene can be opened in Maya 2018. Credit: Matt Chan

This compound automates the process of creating an efficient MPM granular simulation setup.   It computes the intersection of an animated object with a piece of terrain and builds three useful pieces of geometries which can be used for the MPM simulation: (1) A 'source' geometry for sourcing the MPM particles only where the animated object intersects with the terrain geo, (2) A 'container' geometry used as a collision object in the MPM sim, which holds the granular particles in place (lest they fall down due to gravity), and (3) A 'carved_terrain' geometry which simply returns the terrain mesh, post-carving.  It can be useful to scatter points around the granular sim, for rendering purposes.   Note that the terrain needs to be of planar topology, e.g. one-sided - not like box. The terrain and the animated object need to be supplied in the form of file-caches (Alembic .abc or .bob).  A frame-range must also be specified so that the carver knows which frames to consider for the intersection between the animated object and the terrain. A useful tip is to use a low-res terrain mesh (e.g. 10k polygons or less) the first time you try it, as large terrain meshes can bit a bit slow.
