  1. View3ds 0.068 - tiny viewer to .3ds and .asc files with several graphics
  2.                 effects implementation.
  3.  
  4.  
  5. What's new?
  6. 1. Editing option - new 'editor' button.
  7. 2. For now I disable perspective correction, to make implemtation of editing option easier.
  8.  
  9. Buttons description:
  10. 1.  rotary: choosing rotary axle: x, y, x+y.
  11. 2.  shd. model: choosing shading model: flat, grd (smooth), env (spherical
  12.     environment mapping, bump (bump mapping), tex (texture mapping),
  13.     pos (position shading depend), dots (app draws only points - nodes of object),
  14.     txgrd (texture mapping + smooth shading),  2tex (texture mapping + spherical
  15.     environment mapping), bmap (bump + texture mapping),  cenv (cubic environment
  16.     mapping), grdl (Gouraud lines - edges only).
  17. 3.  speed: idle, full.
  18. 4,5. zoom in, out: no comment.
  19. 6.  catmull: on -> use z buffer ( z coordinate interpolation), off -> depth sorting, painters
  20.     alghoritm).Txgrd, 2tex and bumptex models only with catmull  = on.
  21. 7.  culling: backface culling on/ off.
  22. 8.  rand. light: Randomize 3 unlinear lights( so called Phong's illumination).
  23. 9.  Blur: blur N times; N=0,1,2,3,4,5
  24. 10.11,12,13. loseless operations (rotary 90, 180 degrees).
  25. 12. emboss: Do emboss effect( flat bumps ), use 'bumps deep' button to do edges more deep.
  26. 13. fire: do motion blur ( looks like fire ).
  27. 14. move: changes meaning x,y,z +/- buttons  ->  obj: moving object, camr: moving camera, wave: x,y +/- increase,
  28.     decrease wave effect frequency and amplitude.
  29. 15. generate: Generates some objects: node, Thorn Crown, heart...
  30. 16. bumps: random, according to texture.
  31. 17. bumps deep -> create bumps deeper or lighter.
  32. 18. re-map tex -> re-map texture and bump map coordinates, to change spherical mapping
  33.     around axle use 'xchg' and 'mirror' buttons, then press 're-map tex' button.
  34. 19. bright + -> increase picture brightness.
  35. 20. bright - -> decrease picture brightness.
  36. 21. wav effect -> do effect based sine function.
  37. 22. editor -> setting editing option. If is "on" then red bars are draw according to each vertex, Pressing
  38.     and moving left mouse button (cursor must be on handler)- change vertex position. If left mouse button
  39.     is released apply current position. You may also decrease whole handlers count by enable culling (using
  40.     appropriate button) - some back handlers become hidden.
