Texture Compression: Range Coder

One of the key components of the Mip-Differential VBR compression scheme I was looking at next is based on the use of a Range Coder (which is essentially an integer version of an Arithmetic Coder).  This coder is used to do …

Keeping up with my sous-vide obsession these days, I whipped up a few more yummy experiments over the past week. I decided to post early as I will be out of town for the weekend therefore won’t have more time …

Texture Compression: Which Perceptual Error Metric to Use?

I decided to spend a little more time on my variable bit rate DCT coder. Mainly looking at a few perceptual error metrics to see if anything could yield better general results than PSNR. One of the main sources for …

Texture Compression PART 2, Improving DCT/JPEG Performance

psnrdct_12

In this second section, I continued exploring different ways of possibly improving the DCT/JPEG compression in a JPEG->DXT transcoding texture streaming system. In the first part, I took a look at if we could possibly improve JPEG compression by taking …

RIP Steve Lacey… You Shall be Missed!

I just learned the tragic news that one of my best bosses at Microsoft died yesterday of a car accident. Quite a sad event as he was a great guy and leaves behind his wife and two kids. My thoughts …

Enhancing DXT Compression for Better File Storage.

This is a little bit of a sidetrack from my previous project postings but is something that I experimented with a few months ago and is quite relevant to my other texture compression posts and is probably more a prelude …

Trying to Balance Money Making and Fun Projects.

Under my current situation, finances have been tight. Debt accumulated from a marriage that wasn’t going well, spending too much on trivial things, having to pay support for my spouse and just a good amount of bad luck have left …

Texture Compression PART 1, Improving DCT/JPEG Performance

In the first phase of my project, I decided to see if there were possible ways to improve JPEG-like texture compression scheme (such as used in ID’s Tech 5 Virtual Texture system) by taking advantage of the fact that the …

My first Photosynth try, results iffy at best.

Tried to make a photosynth of my new digs. Results were so-so. Probably needed more pictures to get better results but my camera is too slow for my patience to snap every possible angle http://photosynth.net/view.aspx?cid=c2657186-6ddf-4f52-bcde-d4bfb40ba8be
