Lying Throughout Your Career

There was someone who did (have to) leave my company recently. He is one of those people who have to jump around companies after short stays. Yeah, you know why. And today, I happened to read his blog post explaining why he was leaving. A lot of my co-workers enjoyed it because it reminded us of the Lord of the Rings, arguably the best fantasy fiction to date.

Animation Sharing between Different Characters with Same Topology in Unity

So let's say you have multiple characters with different bone lengths, but you just don't have manpower to author different animations for all of them. Can we share animations, instead? Sure, why not, if you can live without transition and scale animations on joints: in other words, you are only gonna use rotations. Think it this way. When you rotate your right elbow inward by 90 degrees, your pose will look same as your shorter friend applying the exactly same rotation on his right elbow. Got it?

"Fix" for ESC Not Working While Photoshop CS3 is Open

So I have had this problem where ESC stops working globally while Adobe Photoshop CS3 is open for a few years. CS5 doesn't suffer from this problem, but getting upgrade to CS5 was not easy because CS3 was the version we were using for Space Marine.

Compile-Time Hash String Generation

Motivation Recently, I worked on a code-base where everything was referenced by strings. It was quite expensive as you can imagine, so to avoid the cost of string comparison, hash values(ints) were used. This system had a giant hash string registry, which generates a hash value and stores both the hash and actual strings whenever the code sees a new string, well all during run-time.

Optimized Oren-Nayar Approximation Shader Code

We presented this approximation code as part of our KGC 2011 presentation. Let me just show the code for those people who don't want to read the whole presentation. I've also mentioned this to Wolfgang Engel during KGC 2011 because our previous Oren-Nayar code was from his wiki book.

One that Daniel and I presented at KGC 2011. First half is a quick overview of our rendering passes, and second half is about Screen Space Decal and World Occlusion technique we used for Space Marine.

Feedback on My KGC 2011 Presentation

After I presented The Rendering Tech of Warhammer 40,000: Space Marine at KGC 2011 with my co-worker, Dr. Daniel Barrero, I was curious what the audience thinks about our presentation. So, here I compiled all the feedback I was able to find on the net. All feedback is pretty positive so far.

I use int 3 for assert()

C has assert() function. Sure.. I don't use it. I don't like the call stack it gives me. It is rather confusing: I want the line with the problem at the top of my call stack. Sure, there's a way to unroll stack for sure. Too much hassle. Instead, I use this for my own assert.

Inside of char* string buffer initialization

I used to initialize a string buffer this way:

Screen-space Lens-Flare in HomeFront?

I consider myself a practical graphics programmer. I believe mathematically correctness is less important than what looks right(or okay) to gamers.
