cl gltf

2.0.0

A library to parse and serialize the glTF file format.

About cl-gltf

This library implements the glTF file format both for parsing and serialising, as well as several extensions to the specification. glTF is a pretty good format for 3D scene interchange and delivery.

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:

(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 accessors, 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.

  Reduces buffers to a single STATIC-BUFFERS. If the glTF already has no or a single buffer, no changes are made. Otherwise buffers are merged to one and all buffer views are adjusted to point to the new buffer. Returns the modified glTF. See SERIALIZE
- EXTERNAL FUNCTION
  NORMALIZE-BUFFERS

  MMAP
  
  Source
  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. See WITH-GLTF See GLTF (type)

  UPDATE-ASSET-GENERATOR
  
  Source
  Serialize a glTF object to a file. This function can serialize glTF files both in textual glTF format with external buffers, glTF format with embedded buffers, and GLB binary format to files and file streams. NOTE: when serialising a file with multiple buffers to a GLB file, this function will call MERGE-BUFFERS for you, which modifies the glTF structure. You may want to call one of NORMALIZE-BUFFERS, MERGE-BUFFERS, URLIFY-BUFFERS prior to calling SERIALIZE to consolidate the buffers to suit the format you want. For instance, if you want to create a single text JSON file, you should use URLIFY-BUFFERS. If you want to create a single JSON+DATA file, you should call MERGE-BUFFERS. If you want to avoid having any data stored in the JSON, you should call NORMALIZE-BUFFERS. If UPDATE-ASSET-GENERATOR is true, the GENERATOR field in the ASSET of the glTF is updated to reflect this library as the generator. See MERGE-BUFFERS See NORMALIZE-BUFFERS See URLIFY-BUFFERS
- EXTERNAL FUNCTION
