normalizeMesh function

List<Mesh> normalizeMesh(List<Mesh> meshes)

Scale the model size to 1

Implementation

List<Mesh> normalizeMesh(List<Mesh> meshes) {
  double maxLength = 0;
  for (Mesh mesh in meshes) {
    final List<Vector3> vertices = mesh.vertices;
    for (int i = 0; i < vertices.length; i++) {
      final storage = vertices[i].storage;
      final double x = storage[0];
      final double y = storage[1];
      final double z = storage[2];
      if (x > maxLength) maxLength = x;
      if (y > maxLength) maxLength = y;
      if (z > maxLength) maxLength = z;
    }
  }

  maxLength = 0.5 / maxLength;
  for (Mesh mesh in meshes) {
    final List<Vector3> vertices = mesh.vertices;
    for (int i = 0; i < vertices.length; i++) {
      vertices[i].scale(maxLength);
    }
  }
  return meshes;
