calculateWorldAABB method

@override void calculateWorldAABB(Vec3 pos, Quaternion quat, Vec3 min, Vec3 max,)

@todo use abstract for these kind of methods

Implementation

@override
void calculateWorldAABB(Vec3 pos, Quaternion quat, Vec3 min, Vec3 max) {
  final verts = vertices;
  double? minx;
  double? miny;
  double? minz;
  double? maxx;
  double? maxy;
  double? maxz;
  Vec3 tempWorldVertex = Vec3();
  for (int i = 0; i < verts.length; i++) {
    tempWorldVertex.copy(verts[i]);
    quat.vmult(tempWorldVertex, tempWorldVertex);
    pos.vadd(tempWorldVertex, tempWorldVertex);
    final v = tempWorldVertex;
    if (minx == null || v.x < minx) {
      minx = v.x;
    }

    if (maxx == null || v.x > maxx) {
      maxx = v.x;
    }

    if (miny == null || v.y < miny) {
      miny = v.y;
    }

    if (maxy == null || v.y > maxy) {
      maxy = v.y;
    }

    if (minz == null || v.z < minz) {
      minz = v.z;
    }

    if (maxz == null || v.z > maxz) {
      maxz = v.z;
    }
  }
  min.set(minx!, miny!, minz!);
  max.set(maxx!, maxy!, maxz!);
}
