So, I’ve been working on a fork. There’s also another one. Both will eventually merge The code is far from finished at the time of writing. But the direction where we’re heading to is already quite clear. You can even glimpse a bit of what’s coming: Yeah, we’re going bindless […]
Understanding how your algorithm works and its use cases is very important. It allows you strip code you will never use (or better yet, never code for it). Or may be this could be seen as a case of overengineering. Such is the example of Ogre’s LodStrategy. There are multiple […]
Ogre Animation is finally shaping up. There’s a lot to do, namely: Add TagPoints Add NEON support Document & samples I have to say I’m glad to see that the new animation component is 2x-3x faster and is able to use 60% of the CPU cores (out of a quad […]
Debugging on Linux sucks. Let’s try to make it suck a little less. I was debugging a bug in Ogre, and after giving up with Linux, in MSVC the issues came up almost instantly after looking at this screenshot (note the bug has been fixed in this shot): With a […]
You may have seen on Mike Acton’s twitter account that he posted a review code on OgreNode.cpp. Seems like some community members are waiting for my response, I made a few comments on bounceapp but due to my inexperience with that site I didn’t realize changes had to be saved. […]
When Ogre 1.x users are far from origin, things begin to shake. Animations flicker. Eyes pop out of their sdockets. Playstation(R) 1 artifacts all over the place. This is because of precision problems with floating point when using large numbers. To help mitigate those artifacts, SceneManager had a setting called “setCameraRelativeRendering”. […]
I’ve upload a DRAFT of Ogre 2.0 Porting Manual. It can be downloaded in PDF format from the following two mirrors: MIRROR 1 MIRROR 2 For those interesting in write access, you can download it in ODT format. The forum thread has been updated as well as the wiki. The idea […]
Phew! GSoC is over. It’s been rough. A lot of fun. I’d hope it could last 3 more months, and we would get Ogre in an awesome state. Well, back to our weekends-only contributions; though I’ll probably be making a few more commits as I’m still accelerated and with some […]
Threading results were disappointing. Well, I was expecting 4x improvement on my quad core machine. The result was between 35-40% improvement which is still something. After a closer look, I ended up concluding that at 250×250 instances we’re memory bandwidth bound (i.e. disabling all math in UpdateAllTransforms and just doing […]
In Ogre 1.x; each Entity has it’s own list of lights, sorted by proximity. This way, when rendering, each Entity sends to the shader the closest N lights and, given enough batches, 8 lights per batch would be enough to lit the whole scene. That’s in theory at least. Until […]
