Hi, please forgive me but...I couldn't find this info anywhere. I know it's
not a DJGPP-specific question, but please see if you can help.
I'm taking my first steps to creating a ray-caster (using DJGPP, of course :)
and I'm stuck with trig lookup tables. See, DOOM/Wolf3D use these things
called 'finesine' and 'finetangent' so that the lookup tables don't need to
be re-calculated everytime the screen is resized, and I would _really_ like
to know how they work. Re-calculating the tables takes a little time, so
there's got to be a better way to do it, and I can't find one ! Can anyone
help me please ??? Thanks in advance, and sorry once again for posting this
here,
Pete =:-)
