The aim of this project is to provide functionality to load COLLADA files into Java for rendering, specifically using OpenGL.
The algorithms within are written for this transformation, since not all of them translate directly to OpenGL. For example, in COLLADA, the geometries have per-type element indices, whereas OpenGL expects a per-vertex element index. JCollada provides this translation.
JCollada aims to be lightweight, rather than a fully featured COLLADA parser.
JCollada consists of an API module and (currently only one) schema-specific implementation modules. Your code should be written against the API module; you only need to have the implementations on the classpath at runtime. You will also need to make sure you have an XmlPullParser implementation, as well as an SLF4j logger implementation. By default, these are included in the JCollada dependencies as runtime dependencies. However, you should be able to swap out those dependencies for your own preferences.
You are, of course, able to download the source, build it yourself, and use it however you see fit. The packaged gradle wrapper should be enough to get you started if this is your interest.
However, you would probably like to use a snapshot or released version that you know works. In that case, you have two urls which are available:
- Snapshots at http://dev.dryanhild.net:8080/nexus/content/repositories/snapshots/
- Releases at http://dev.dryanhild.net:8080/nexus/content/repositories/releases/

A little bit of a minor release, but reworked a little bit of the API for interleaved data.
- Added version information to the .jar itself.
- Added test coverage, license headers, more logging.
- Added an integration test suite. Eventually this should hold some examples.
Reorganized a lot of internal code & restructured some of the API. Internally, now using the HK2 library to perform some of the dependency injection. Version detection and support is still done through the java service provider framework.
- Can load simple and elements in a geometry.
- Resulting document structure is now easier and cleaner to use.
- Currently supported formats are 1.4.0 and 1.4.1.
- Gradle is now used in lieu of maven for building the projects.
Initial implementation for loading COLLADA files.
Features:
- Ability to load a single .dae file when given a Reader to that file.
- Parsing geometry meshes that contain polylist elements which have vcounts of 3.
- Loading the basic visual scene / node hierarchy so that these elements can be accessed.
- Ability to reference geometries, nodes, and visual scenes through URI addressing.
