the matrix was a documentary
Seeing as performance has been on my mind recently, I tweaked the core render loop a bit and saw some reasonable gains. The one thing I realized is that most of the objects in the scene are static, and don’t need their combined transformed matrices recalculated every frame. I
I don’t have much time, so I will be brief. Basically for the past few days I have been trying to optimize the engine. With the stress test you see above (around 13K cubes) I was only getting around 200 fps. Just slightly above my target of 120
Today I have gotten the camera system to a decent place, and made a simple free look demo. Most of the code had already been implemented, inside the vector and matrix classes, I just had to piece it together into a camera object. I also added a
Though the above video might not seem like an overly impressive jump from the last, there’s actually a ton of work behind it. The new additions include a node-based scene graph hierarchy, more robust math libraries, and keyboard control using DirectInput. Plus, I’ve tried to abstract as much as I
The demo is starting to shape up now, with texture mapping and some simple lighting (ambient and directional). To be fair, I’m not sure if I would really call this an “engine” quite yet. It’s still very much a bare-bones, hard-coded demo done in DirectX 11. But
Today I have finally gotten a simple sort of animation working. It looks easy, but I made my life a lot harder by implementing by own math library. So far I have a Vector3D and a Matrix4x4 class almost finished. Well the Vector class is pretty much
So I buckled down and spent the better half of the day actually getting something to show on the screen. Yes, it’s still just a triangle, but it feels pretty satisfying after struggling to get it to work all morning. While there are tons of triangle tutorials online, and
Beginning DirectX 11 Game Programming by Allen Sherrod is, what I’d consider, a great introduction into DirectX programming. Just to be clear, it’s really only an overview of the DirectX APIs (Direct3D, DirectInput, etc.) and not really a graphics or game programming book (despite the title). So there
I know it has been quite some time since the last update, and I thought I would be much further by now. Truth be told, I have been a little distracted the last few months with things totally tangential to graphics programming. In any case, I’ve had some
Alan Thorn’s Game Engine Design and Implementation was quite an interesting read. Overall I thought it was good, but the book struggles at times to find it’s audience. On one hand, it covers a lot of great topics and there are some good code snippets to be found. On
