Fixed Integer Math?

[CARPEDIEM]

Well actually im aware of Jacco's work, he's a buddy of mine, I even included his 3d engine on my GAPI Benchmark and ported it to Jornadas and Casio's. I get 6fps on my e-125 @ 180 and a jornada gets 3 fps.<br>But what i was thinking in doing when i encountered the floating point problem, is to make a C++ Class called FixedPoint that would actually be just like doubles. If you could get your hands on a class such as this, probably your problem would be just to replace the keyword Double for FixedPoint.<br><br>But making a FixedPoint Data type is not an easy task of course.<br>

Using a class would work very well.  However, Quake is in C, so some non-trivial modifications would be required to change it to cpp.<br><br>Dan East

If the quake engine is using doubles you may see some speed up just switching to floats.... less bits in each operation.<br>
