parse-pc2

Parse .PC2 vertex animation files. Demo.

Installation

Blocking API

var pc2Parser = require('parse-pc2')
var parsed = pc2Parser.toObject(fs.readFileSync('/path/to/animation.pc2'))

Stream API

var pc2Parser = require('parse-pc2')
var parser = new pc2Parser.StreamingParser()
parser.on('readable', function () {
  var parsed = parser.read()
  if (parsed) {
    // Use parsed data
  }
})

parser.write(buf)

Object Structure

The following object structure is returned by both parsing APIs:

{
  numPoints,  // Number of points per sample
  startFrame, // First sampled frame
  sampleRate, // How frequently to sample (or skip) the frames
  numSamples, // How many samples are stored in this file
  
  frames: [
    // An array per frame
    // Each containing "numPoints" vertex coordinates
    [ [x, y, z], [x, y, z] ]
  ]
}
