[gameprogrammer] perspective correction

Hi!
I'm working on some simple 3d engine for symbian phones.
I made a very simple method to draw a textured triangle, however it's 
ugly due to the need of perspective correction.

What is the best way to implement it?

I think in the old days I read that quake implemented perspective 
correction only for the n-th pixel. That means that when rendering a 
scan line from the triangle it recalculated the texture coordinates at 
every n-th pixel, and for teh rest it interpollated?

Thanks in advance for the info!
