addInts method

int addInts(List<int> values, String type, int componentType, { bool normalized = false, bool indices = false, })

Adds integer data of componentType (5121 ubyte, 5122 short, 5123 ushort, 5125 uint), optionally normalized.

Implementation

int addInts(
  List<int> values,
  String type,
  int componentType, {
  bool normalized = false,
  bool indices = false,
}) {
  final width = const {'SCALAR': 1, 'VEC2': 2, 'VEC3': 3, 'VEC4': 4}[type]!;
  final ByteData data;
  switch (componentType) {
    case 5121:
      data = ByteData(values.length);
      for (var i = 0; i < values.length; i++) {
        data.setUint8(i, values[i]);
      }
    case 5122:
      data = ByteData(values.length * 2);
      for (var i = 0; i < values.length; i++) {
        data.setInt16(i * 2, values[i], Endian.little);
      }
    case 5123:
      data = ByteData(values.length * 2);
      for (var i = 0; i < values.length; i++) {
        data.setUint16(i * 2, values[i], Endian.little);
      }
    default:
      data = ByteData(values.length * 4);
      for (var i = 0; i < values.length; i++) {
        data.setUint32(i * 4, values[i], Endian.little);
      }
  }
