WebBufferGeometry is three.js's way of representing all geometry. A BufferGeometry essentially a collection named of BufferAttribute s. Each BufferAttribute represents an array of one type of data: positions, normals, colors, uv, etc... Together, the named BufferAttribute s represent parallel arrays of all the data for each vertex. WebBufferGeometry This class is an efficient alternative to Geometry, because it stores all data, including vertex positions, face indices, normals, colors, UVs, and custom attributes within buffers; this reduces the cost of passing all this data to the GPU.
