Yingying Z shows how to create clouds by advecting a volume in Bifrost, plus some other tricks.
The last in the series to better understand Volumes in Bifrost, Autodesk’s Yingying Z, walks us through a method to create clouds through volume advection.
The process starts with a mesh that converts to a volume and generates a voxel field. Advecting the voxel field gets the cloud look and also provides density data. The whole thing converts back to a volume to form the cloud.
