Today I released an open source project I’ve been working on for the last week, Optix.NET. It’s a lightweight wrapper around Nvidia’s Optix GPU ray-tracing library. I figured since there ar...

Bethesda released a new trailer for Prey 2. I'm not gonna lie, it looks awesome.

Bethesda posted a screenshot and concept piece from Prey 2 today: http://bethblog.com/index.php/2011/04/07/sneak-peek-at-prey-2/

This comes a little later than I wanted, I hadn’t factored in Crysis 2 taking up as much of my time as it did last week :-) I’ve been using Nvidia’s Optix raytracing API for quite so...

I've been working on a new sample for the past few days, Instant Radiosity using Optix and DirectX. I should have a writeup and sample in the coming week. Here’s a few shots with the obligato...

Human Head has been keeping me busy since I've been working there and I can finally say why: PREY 2. The game was announced on Monday :) Here's the Prey 2 teaser trailer: Xbox 360 Games - E3 2...

Last week I attended SIGGRAPH 2010, and among the many good presentations, Valve game a talk on the simple water shader they implemented for Left For Dead 2 and Portal 2. So on the plane rid...

Finally, here is the last sample on volume rendering. It’s only taking me a year to get around to finishing it. Is anyone even visiting this page anymore? I’d better post this for my sanity a...

Wow, it’s been over a year since the last post on volume rendering! I must sound like a broken record. Anyhow, I’ve had time to fix a couple of bugs with the last installment in the past coup...

I got an email a couple of weeks ago from someone ( Maximinus ) who actually put the water shader from the water game component to good use. Here's a description of the game on the xbox indie ma...

Really cool video I found last night. Uses Particular and Adobe After Effects.

Recently I’ve been playing around with O3D. If you don’t know, O3D is Google’s new browser graphics API. It enables you to develop 3d interactive applications that run inside a browser wind...

I recently got back from my vacation to the Mediterranean and finally have had time to post this video. For one of my final projects last semester I implemented a deferred renderer with SSAO and...

Wow, I can't believe it's almost May already. I also can't believe my last post was back in February! I've had the next installment in the volume rendering series basically done since January. I ...

The discussion on hand this time is optimizing the performance of the volume renderer. I’ll cover a few of these optimizations and provide a rough implementation of one of them. CACHE EFFICIEN...

Last time I introduced the concept of volume ray-casting. And to follow that up, today I'll talk about transfer functions and shading. Mummy (top) and Male (bottom) volumes colored with a ...

Pictures above from: http://www.cs.utah.edu/~jmk/simian/ There is quite a bit of documentation and papers on volume rendering. But there aren't many good tutorials on the subject (that...

I had some requests awhile back for a more independent water effect that I had provided in my camera animation tutorials. And just the other day I remembered that I had totally forgot about th...

This semester I've been taking a class in scientific visualization. It's pretty interesting and it covers a lot of techniques such as color visualization, human vision and color perception, conto...

I don't have a new sample/tutorial today. I have been very busy with interviews, research, and school as of late. As this is my last year of school, I've been interviewing with various companies...

There are a few posts that I have seen other blogs/sites that I think are interesting, and would like to share with anyone who reads my blog. Andy Patrick has a series of useful "efficient devel...

Edit: Added the video that I recently made I have to say, I really like variance shadow mapping. It's such a simple(ingenious) technique to implement, but it provides such nice looking resu...

Last time I introduced using dual-paraboloid environment mapping for reflections. Well now we're going to apply the same process to shadows. So if you haven't looked at my previous post, read...

I recently had to investigate dual-paraboloid reflections at work for an unnamed console. What are these you ask? Great question! :) Lets start with some background. The standard way of cal...

I figured I would release my source for the terrain rendering demo. There aren't that many terrain and atmospheric scattering examples on the net, so I figured I might as well post mine for ...
