title: Buffer manual

brief: This manual explains how Buffer resources work in Defold.

Buffer

The Buffer resource is used to describe one or more streams of values, for instance positions or colours. Each stream has a name, data type, count and the data itself. Example:

[
  {
    "name": "position",
    "type": "float32",
    "count": 3,
    "data": [
      -1.0,
      -1.0,
      -1.0,
      -1.0,
      -1.0,
      1.0,
      ...
    ]
  }
]

The above example describes a stream of positions in three dimensions, represented as 32-bit floating point numbers. The format of a Buffer file is JSON, with file extension .buffer.

Buffer resources are typically created using external tools or scripts, for instance when exporting from modeling tools such as Blender.

A Buffer resource can be used as input to a Mesh component. Buffer resources can also be created at runtime using the buffer.create() and related API functions.
