Custom 2D Physics in Unity Using Verlet Integration

So 2017 will be my year of “doing the work,” a line I learned from Steven Pressfield in his excellent book named, unsurprisingly, “Do the Work.”  I’ve spent literally years reading about 3D math and physics and, outside of a few small demos I’ve experimented with and never released, I haven’t actually produced anything. I’ve also been inspired and motivated by a variety of

Review: Beginning Math and Physics for Game Programmers by Wendy Stahler

Beginning Math and Physics for Game Programmers by Wendy Stahler is the kind of book I like. The title is straight-forward, and the content actually delivers what it claims. I’ve read a number of game development math books but I find that many of them expect a college level mathematics background, or at least some intermediate knowledge already. Not here. This is a

Creating a 3D Game Engine (Part 24)

  It’s been some time since the last 3D engine update, but I’m still sticking with it. Currently I am working on getting a physics engine implemented. The video you see above is the first glimpse of this custom physics engine. Obviously it’s ultra basic right now, but it’s a start. The algorithm is based on a verlet integrator, and the code is

Review: Physics for Game Programmers by Grant Palmer

Today I will be reviewing Physics for Game Programmers by Grant Palmer, another stepping stone on my quest to build a custom physics engine. Overall I enjoyed reading the book, and I feel like I learned a lot of general things but not enough to base a physics implementation on. Please read on for more details. What I found most interesting about this

Review: Game Physics Engine Development: How to Build a Robust Commercial-Grade Physics Engine for your Game by Ian Millington

In this review, I will discuss my experience with Game Physics Engine Development: How to Build a Robust Commercial-Grade Physics Engine for your Game by Ian Millington. This is actually the first book I’ve ever read solely on game physics and I think I made the right choice here. Although I have developed several physics engines previously, they were only in 2D and the

Insane Physics Simulation From Nvidia

  This has got to be one of the more insane physics demos I’ve seen so far. Most physics engine handles the basic rigid bodies and such, but start to fall apart with more complex interactions (i.e. fluid and cloth simulations). With the demo shown above, from Nvidia, it seems these difficult problems have been solved. Cloth, fluid, smoke, and rigid or soft bodies, all
