Don’t get left behind

Do you want to know what the latest trends are in game development? Do you have a fear of being left behind in the game dev industry because you don’t know what such n’ such a technique is? Is there something you can do to make sure you’re not left behind in the dust? ┬áThere is!

In this post, I’m mainly concerned with physics and graphics, but the same sort of techniques apply to other fields as well. The following items are what I do regularly to keep up to date in my field:

Physics Engine

Physics engine in action

Description: This is an implementation of my physics engine that I developed during my PHY350 class at DigiPen. There are many more features I would like to add to this physics engine, so once I get out of school, expect to see a more advanced engine. Expect integration with my other engine which includes articulated figures, hierarchical based animation system, path following, path finding, Inverse Kinematics, and spring based cloth physics.
