Blobs are alive. They breathe (if you code vertex breathing). They merge. They separate. They drip.

is therefore the practice of generating, manipulating, and simulating volumetric, blob-like organic meshes in real-time, inside a virtual reality environment. Unlike traditional polygons (which are hollow shells), BlobCG utilizes voxels or signed distance fields (SDFs) to create objects that are solid all the way through and can fuse with one another spontaneously.

Think of the T-1000 from Terminator 2 , but you are holding its arm, stretching it like mozzarella, and then merging it with a sphere to create a chair. That is VR BlobCG. To truly understand the "Blob" part of VR BlobCG, you need to understand Metaballs .
