  1. Radio Shack archives auction

    Wow, thanks for posting this info. Apparently the shipping could be an issue on some items and the 36 day to close is a little long.
    Things like the acoustic coupler will be interesting to follow.

    I am planning on going to the local store in about an hour for a "special event" this morning.

  3. Simplifying Backface Culling

    The process of culling backfaces is simply checking the visibility of one-sided polygons based on whether they are facing towards the camera / player or away. If they are facing away then it is a back-facing side, rather than front-facing, and must be skipped during rendering. To determine this, I must calculate a normal vector. Every 3D triangle has two of these normals: one points outward from it and one points inward. The one you get depends on whether the calculation is made from vertices going ...

  5. Coordinate Rotation using Fixed Point

    The goal here is to quickly rotate points by a certain number of degrees using precalculated SINE/COSINE values and without floating point, e.g. only integers. In order to do that I am using fixed point [1] and a lookup table. So first I want to discuss fixed point a bit to get our feet wet.

    Fixed point is a technique where one designates a number of high bits in an integer to the whole portion and leaves the remaining lower bits to represent a fractional part. This is usually expressed ...
