i actually couldn't care less about graphics, i just want to hear about his rockets and spaceships he chose on a whim on some ordinary day, to learn about and build.

I was interested when he started talking about how most of his work just requires a good understanding of the upper high-school level math courses, not advanced college level math. Having just finished a college Business Calculus course myself this stuff is all still on my brain. He then went on to say that graphics calculations involved calculating the derivative. Basically he was saying that he uses linear math and takes that simple line and calculates the slope of that line. The derivative or slope of the line is the key.

Makes sense, get to the solution as quickly as possible.

John Carmack is certainly my idol when it comes to video game programming. His knowledge and wisdom of video gaming tech is godlike. I hope some day I can be as knowledgeable as him.

Here are some of the topics I can remember off the top of my head:

* PC GPU drivers have a big overhead. One function that might be straight to the point on consoles might do very many unnecessary calculations on the PC.

* Keep an eye out for Intel Graphics. They certainly aren't the joke they were in the past. They certainly are capable of improving a lot more too.

* Experimenting a lot with Ray Tracing.

* "Unlimited Detail" has been experimented around with for many many years now but doesn't really work out.

* Beware of tech demos. They don't take into account many of the features that production quality games have. Without these features frame rates are significantly higher than they really would be.

* The next "big jump" in immersion will probably come from I/O. He envisions a type of goggles that will feature a type of display that will give you full visual immersion.
