For some stupid reasons, my website had crashed down for 3 months. Because I was quite busy to prepare interviews and exams, I had no time to dispose the problem. This weekend, I spent all of my free time to recovery it and the good news is: bei kun’s private home is back! I’ll try to writing the articles which should be written in these 3 months. And I’m now working on a graphics part of Xenko game engine, so if it’s possible I’d like to share some technique details with you. Wish you can enjoy them and happy to see you still here!
