BioDigital Summer Intern Review 3 - Cross Section

Aug 27, 2016

Cross section is a feature that can be very useful and heavily used in WebGL app for medical and architecture usage.

Basically it’s when given a set of clipping planes, we should clip the geometries that fall outside of the clipping planes, and draw the clipping caps. In addition, we would prefer a dynamic real-time solution which doesn’t need any predefined knowledge of the geometries.

BioDigital Summer Intern Review 2 - Camera tricks - Mouse Orbiting issue

Aug 26, 2016

Continuing our last blog, we are looking at some other issue of camera in WebGL apps with a display stage style scene.

Another common camera issue in these apps is that after we pan the camera, orbiting becames kind of weird. This is because we orbit camera around its look at position, and now look at position is not centered at the object anymore. Lacking of other referencing scene objects (like terrain, walls), the orbiting seems to us like floating in the air doesn’t follow control nicely.

BioDigital Summer Intern Review 1 - Camera tricks - Cylindrical coordinates

Aug 26, 2016

In this first review, I will introduce some tricks that can help make the camera behaves more user-friendly for a display-stage style 3D app.

VSCode Typings and Intellisense: Dummy Learning VS-Code 1

VSCode Useful shortcuts and tricks: Dummy Learning VS-Code 0

Jun 20, 2016

As a dumb programmer, I am always hoping that I can become one of those geeky and experienced programmers who type rapidly and barely leave their hands from the keyboard when typing in a text editor. Learning more about a text editor sometimes save you a great ammount of time. Although there’s always a way to detailed documents, I would still appreciate a simple straightforward chi-chi for tricks of using text editors. It doesn’t have to be too advanced which including every trivial tricks or introduce all sorts of customizable plugins, but can still be very useful especially for a newbie to start rolling with the text editors.

That’s why I have this blog series about tricks of using text editors, VS Code as the selection, for it is totally free and doesn’t need many plugins to start with. JavaScript will be the main language that we are writing.

This first blog will start with some very basic but useful tricks.

Nyc Webgl Developer Meetup

You can develop your species in the track of a herbivore, a carnivore, or plants that live on self generated energy!

MechEmpire-Clash at PennApps XII

Sep 4, 2015

MechEmpire-Clash is a multiplayer 3d shooting game, players can join the game and control their robots either with their mobile device (with support of EA pathfinder API), or with classical mouse and keyboard.
The ideas, models, and game background are adapted from MechEmpire. Basically I want to make this game an extension of MechEmpire Series, which can include AI agents programmed by contestants in the future. I hope this game together with MechEmpire can be continuously developed and help people learn programming happily.

MechEmpire 机甲帝国

Jun 8, 2015

MechEmpire is an AI agent programming game, consisting of a Game Core, 2D(Flash)/3D(Unity) Game Renderers, a Website with an Arena System, and Models and Designs of the mechs. Comparing to other programming games, it focuses more on playability and game experience. A large variety of weapons and engines are available for different types of tatics, which brings a lot of fun to the programming game.

I created MechEmpire from scratch in 2013. So far I have met some great teammates and we have succeed holding two Competition Seasons, attracting students from Southeast University, UCLA, The University of Electronic Science and Technology of China, and etc. MechEmpire has also been working as a registered SRTP competition in SEU. It is the greatest time of my undergraduates working with these guys.

Heroes Gathering

Aug 20, 2012

Hero Gathering (英雄集结号) is a project for the programming and algorithm class when I was freshman. Because of this, to bring in as many technical elements as possible regardless if it’s suitable (ODBC, Win32, flash, …), it turns to have a really wired structure and very hard to distribute.
The game idea itself is not bad though. Players gather heroes like pokemons, and the turnbased battle has a special system similar to rock-paper-scissor which makes it possible for zeros beat heroes. Even in 2015, I still spent a whole day just playing this game -_-!.

108 Heroes

Jan 30, 2012

108 Heroes (水浒英雄传) is an Adobe Flash ARPG game I made when I was a freshman. The code is in outdated AS 2, and is very ugly. But the game itself is fun. As a fan of Water Margin (水浒传), I brought all the 108 heroes into the game. Each of them has an appearance(only finish drawing about 50% of them, haha) and a different weapon. Players will recruit other heroes, buy gangs and horses, and fight with other factions to capture more mountain camps.
