The cl-gltf Reference Manual

1 Introduction

## How To
For the purposes of this tutorial we'll assume the package ``org.shirakumo.fraf.gltf`` has the local nickname ``gltf``. After loading the library, you can parse a glTF or GLB file as follows:

:: common lisp
(gltf:with-gltf (gltf #p"my-model.gltf")
  (describe gltf))
::

``describe`` will emit the full structure of the parsed glTF file. From there you can use the accessors from this package to traverse the structures and convert the information as you need.

Of particular importance are the ``accessor``s, which provide a convenient way to parse out the information from the raw underlying byte buffers that they index into. An ``accessor`` is a ``sequence``, so you can simply use ``length`` and ``elt`` to traverse the data.

However, note that cl-gltf makes no assumptions about a math library or anything of the sort, so by default it will parse the data out to vectors of the respective element type (usually floats). That buffer will also be shared between ``elt`` calls to avoid excessive consing. Thus, if you are just copying the data out of the buffers to another place, this should be ideal.

However, if you would like to customise the way the data is read out, such as to convert it into other structures automatically, you can do so. Either set the ``element-reader`` function on the accessor, or provide a specialised method on the ``construct-element-reader`` function. See the respective docstrings for more info.

## To Do
The following are still left to do:

- Loading from pointers or byte arrays
- Direct support of the ratified extensions
- Writing files

2 Systems

5.1.1 Macros

Macro: with-gltf ((gltf file) &body body) ¶

Parses a glTF file and handles cleanup safely.

GLTF must be a variable to which the GLTF instance is bound within the execution of BODY. It is **not** safe to let the GLTF instance escape from the body.

See PARSE
See GLTF (type)

Package: org.shirakumo.fraf.gltf.
Source: parser.lisp.

5.1.2 Ordinary functions

Function: parse (file) ¶

Parses a glTF file and returns the constructed GLTF instance.

This function can parse glTF files in both textual glTF format with external buffers, glTF format with embedded buffers, and GLB binary format from files, strings, and streams.

Note: you **must** call CLOSE on the glTF file or its individual buffers when you are done with the file. Failing to do so will cause file descriptors or other resources to stay allocated indefinitely. It is therefore strongly recommended that you use WITH-GLTF to handle the resource cleanup safely.

Consequently, any access to BUFFERs, BUFFER-VIEWs, or ACCESSORs after CLOSE has been called on the GLTF instance or the respective underlying buffer leads to undefined behaviour. DON’T DO IT.
