Ray Tracing

Really, another Minecraft article?

Updated: 2010-09-29 14:26:49

Here at RTR HQ we like to consider ourselves trailing edge, covering all the stories that have already been slashdotted and boingboinged, not to mention Penny Arcaded. My last post included the simulated 6502 project. The madness/brilliance of this ALU simulator boggles my mind. Yes, Minecraft is awesome, and for the low low price of $13.30 it’s had [...]

Peripherally-Related Links

Updated: 2010-09-22 02:41:56

Here are a bunch of links to things that are graphical, but definitely not about hard-core interactive rendering. Basically, it’s stuff I found of interest that has a visual and technical component and that I’m compelled by the laws of the internet to pass on. It’s a pile of candy, so I recommend reading just [...]

Quick Gaussian Filtering

Updated: 2010-09-21 02:17:42

There are two speed tricks with Gaussian filtering using the pixel shader. The first is that the Gaussian filter (along with the box filter) is separable: you can filter horizontally, then vertically (or vice versa, of course). So for a 9×9 filter kernel you then have 18 texture samples in 2 passes instead of 81 [...]

Clearing the Queue (a little)

Updated: 2010-09-09 03:29:27

Well, let’s see how far I get tonight in clearing the backlog of 219 potential resources I’ve stored up. Here goes: NShader – If you use MSVC and you write shaders, this one’s for you. It highlights shader text as you’d expect, highlighting function names correctly and generally making code more readable. Worthwhile, I’ve installed [...]

Some quick bits

Updated: 2010-09-08 03:24:24

We’ve updated our portal page a bit: added Black Rock Studio’s nice publications page, added some film and commercial research labs’ publication pages, and fixed some links. Also, with a bit of regret, I removed the links to the Google Group pages for comp.graphics.algorithms and comp.games.development.programming.algorithms (though the FAQ for c.g.algorithms is still handy). These [...]
