Collada

This library provides support for loading and processing data from Collada Digital Asset Exchange files. These files are typically used for sharing geometry and scenes.

Build Status

Installation

Add this line to your application's Gemfile:

gem 'collada'

And then execute:

$ bundle

Or install it yourself as:

$ gem install collada

Usage

This library is designed to be used in scripts which extract data from collada files and output in some other format. As such, you'd typically create your own conversion script which takes the collada file as an argument. Then, use this library to extract relevant geometry and write it out.

To assist with some basic tasks, the collada-convert executable provides a number of basic conversion functions. At present, collada-convert is primarily designed to produce tagged format text.

Example Conversion

Several example .dae files are included and used as part of the unit tests. The collada-convert executable can dump the geometries contained within easily:

$ ./bin/collada-convert tagged-format -v p3n3 ./test/sample.dae
