Pagers in Luminocity

December 3, 2004 – 2:37 pm

I’ve been spending some time again this week on Luminocity; mostly redoing the texture handling code. With the rewrite, it can break windows larger than the max allowed texture size into multiple tiles, and I’ve also added mipmap support. After getting the mipmaps working, I quickly hacked up live thumbnailing pagers: From a code perspective, […]

Many years ago, when Microsoft first added TrueType support to Windows, I remember being very impressed by a demo where a text string was rotated and drawn in different colors.

With the work I’ve been doing recently with luminocity, I realized that I had absolutely no idea of what was going on for video card memory usage. Rather than putting some one-off print statements into the card driver, I decided to try and make something a little more reusable and convenient. That Sunday-afternoon project ended […]
