another boring intro:

  ... so here's something more about 3d rotation. this package
  includes all the sources and stuff from the previous version
  (1.0) so you don't need it in any case. in this tutorial i want
  to continue with making 3d rotation and adding some more
  complicated things in it (simple shading, some texture mapping
  ) plus speeding it up a bit. this tutorial is still in pascal
  (that is not because pascal is fast/good, but because i can't
  program in anything else ). since the synergists explanation is
  too simple and it doesn't cover the perspective, shading and
  texture  mapping, i decided to write something about it. you'll
  find the explanations in the .pas files.  i hope you'll enjoy
  this tutorial.

  *!* warning *!*: this version (1.8) is beta and is not the
  final product. The final version (2.0) will be released

contains:

  3dbasics.txt - a simple explanation by synergist.
  3dtutor2.txt - this text.
  fh.nfo       - something about me, unimportant.
  gods02.nfo   - something about the demogroup gods.
  file_id.diz  - guess...

  tut1.pas     - 1st step: 3d-rotation of one point.
  tut2.pas     - 2nd step: rotation of a cube.

                 

  tut3.pas     - 3rd step: rotation of any object, interactive.

                 

  tut4.pas     - 4th step: a bit faster, with precalculated
                 sin&cos.
  tut4.pcx     - helps to understand the perspective

                 

  tut5.pas     - 5th step: simple perspective added + explanation.
  tut6.pas     - 6th step: flat-shading on a cube + explanation.

                 

  tut7.pas     - 7th step: texture mapping + explanation.
                 (* soon *)
  tutunit.pas  - graphical unit with all the procedures and
                 functions.

  sample objects for tut3.pas, tut4.pas and tut5.pas:

  tutor_1.dat  - old good cube. (8  points, 12 lines)
  tutor_2.dat  - a pyramid.     (5  points, 8  lines)
  tutor_3.dat  - something odd. (18 points, 48 lines)

thanx:

  synergist - for his explanation.
  kmc       - for the shading and some help in pascal.

greetz:

  mato      - you _are_ working on the doom64k, aren't you?
  thefaker  - now i've got my own unit ...
  kiwidog   - your tutorial is better, but for how many years
              have you been coding? (i code for 1 year in general
              and 4 months in demos).

history of 3dtutorial:

  v1.0  1/1/1996
   - initial release
   - four steps + explanation
   - covered simple rotation (just lines, no fills)
   - put together in a week after i started to learn 3d
   - surprisingly it got ***+ in demonews

  v1.2с 2/14/1996
   - added one more step with simple perspective
   - some bugfixes
   - this version was never released due to some problems with my
     computer

  v1.8с 4/27/1996
   - one more steps (so now it got 6 steps) with shading
   - texture mapping will be added *soon*
   - added a crappy pcx that helps you understand it better
   - another bugfixes
   - released just few days after i learned these things myself
     (after a two months break off the scene having somthing more
     important to do - school)

   - hope it'll get at least the same rating as the last time... :-)
