Welcome to the Bifrost Clouds lab
This lab is newly made and is supposed to be a supplement for an advanced lecture. As such, most of the information will be in the lecture slides and video attached. In the future, this lab will be populated to act like a normal lab

Node Structure
Main Graph
We’re scattering points along a plane and then converting those meshes to a volume. After that, we move the volume based on an iterative advect field before outputting it to the terminal
Scatter Geo Graph
We’re scattering a bunch of points on a plane, randomizing their scale and rotation. Then on each point, we create instances of the Cloud Geo and turning those instances into a mesh.
After that, we displace the cloud points so they look more natural before outputting the final mesh
Displace Cloud Points Graph
We’re first squashing the sphere so it’s more flat. Then we’re getting each geometry point and increasing the height of it while keeping the bottom flat. After that, we apply some noise to give it more shape and outputting it
Iterate Graph
We’re feeding an advect field into itself the max_iterations number of times. Based on each time we’re doing it, we’re lowering its intensity and time_step
Useful Compounds
- mesh_to_volume
converts as mesh to a volume - volume_to_mesh
converts a volume to a mesh - volume_scope, vector_field_scope, etc
provides diagnostic info. Plug geometry into bounds to limit its range - terminal
provides a better way of separating out your outputs than the output compound. Final is for rendering, proxy is for viewport, and diagnositc if for diagnostic info
