the matrix was a documentary
While I implemented frustum culling a little while ago, I never actually coded a proper bounding volume. For the bounding test I was using a sphere, but I just set the radius to some hard-coded value. This was fine when I just had a bunch of similar sized
After struggling for a bit with the shadow mapping implementation, I finally have something presentable. I followed a tutorial from Microsoft and thought I understood what was happening. However, it required a lot of changes in the rendering code and it took a little while to get things
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.
After a few days of hacking away at the code, I’ve got a new video up. In this update I have added normal mapping and specular lighting. I did have a few set-backs while working on the shaders, and it was made even more difficult since I was
Spent the last couple days adding in skybox support into the engine. Currently it’s a little hard-coded, but it does seem to be working well. I also bumped the field of view (FOV) up to 90 (from 45) so you can see more of the sky. I wanted
While getting models loaded was pretty exciting, I ended up dealing with major load times on the demo. Granted, my XML parsing code is probably slow as all hell, but I don’t think COLLADA is really designed for real-time engine use. With simple plane and cube shapes the
What you see above is a custom model I made in 3ds Max, exported as a COLLADA *.dae file, and imported into my DirectX engine. I figured I’d start with something simple, like a soda can, and I plan to make a lot more models going forward. Although
Programmer art is great and all, but I’d really like to see some complex models inside the engine. Unfortunately, DirectX 11 does not include a built-in way to load in 3D models. As I’ve mentioned before, I am interested in using COLLADA has the import format. Since COLLADA
After some more testing, it looks like OGRE is not the savior it seemed like yesterday. While the static geometry boosted frame-rates greatly, it’s only useful for, well, static objects. Meaning the models can’t move or animate. I did find another option, instancing, which initially looked promising. It
Looks like I spoke too soon. While OGRE was getting pretty slow with the naive implementation, I was able to find some code on what they call StaticGeometry, which is a system to batch together lots of similar meshes that don’t move (great for my cube example project).
