| | | | | Aliasing is everywhere in graphics. Almost everything we do uses discrete sampling, which means almost everything can produce a variety of aliasing artifacts. The folks in the film industry have historically taken a "no aliasing allowed" stance in their work, but in real-time graphics we're still producing games with more sparkling and shimmering than a glitzy prom dress. If we're going to do anything about that problem, I think it's important that we all try to have at least a basic understanding of signal processing. | |

| | | | | Large voxel terrains may contain millions of polygons. Rendering such terrains at a uniform scale is both inefficient and can lead to aliasing of distant objects. As a result, many game engines choose to implement some form of level of detail based rendering, so that distant terrain is rendered with less geometry. http://www.youtube.com/watch?v=4S1sYUHV20s In this... | |

| | | | | This week was a lot of under the hood improvements. The voxel engine got a TON of performance optimizations, which allow my Nvidia GTX 260 to render my test scene at 100-200 FPS. Screenshots: New features: Rough-draft tutorial level with instructions and whatnot. Fullscreen toggling on-the-fly by hitting F11 Rudimentary fog effect Performance optimizations: Voxels are now rendered as surfaces, rather than complete cubes. This lets me cull a lot of unnecessary geometry. Voxels are now split into chunks. This lets me easily implement frustum culling and view distance, which helps tremendously with shadow map rendering as well. I fixed some bugs in the voxel modification code, making voxel modifications of up to 100-150 cells practically instantaneous. Shadow m... | |

| | | While the idea of deferred shading/deferred rendering isn't quite as hot as it wasyear or two ago (OMG, Killzone 2 uses deferred rendering!), it's still a cool idea that gets discussed rather often.People generally tend to be attracted to way a "pure" deferred renderer neatly and cleanly separates your geometry from your lighting, as well as the idea of being able to throw lights everywhere in their scene.However as anyone who's done a little bit of research into the topic surely knows, it comes with a few drawbacks. | ||
